Handle Exception in Update panel(asp.net Ajax and Error/Exception Handling)

Problem: While using Ajax with asp.net, if we get crash on any event which was fired by a control in a update panel we do not get any yellow screen or error page. And end user does not get any message or result.

Solution:

Step-1: Add OnAsyncPostBackError event to the script manager and set AllowCustomErrorsRedirect property to true.

<asp:scriptmanager allowcustomerrorsredirect="true" id="smBody" onasyncpostbackerror="smBody_AsyncPostBackError" runat="server"></asp:scriptmanager>

Step-2: Add the following script after the script manager(Otherwise you will get javascript error on the page).

<script type="text/javascript">

      Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);

</script>

Step-3: Add the following script to the page:

<script type="text/javascript">

    function EndRequestHandler(sender, args) {

      if (args.get_error() != undefined) {

        var Error = "Error Code: " + args.get_response().get_statusCode() + "\nError Message: " +

                    args.get_error().message;

        alert(Error);

        args.set_errorHandled(true);

        //Uncomment the following line to refresh the window after alert the error message.

        //window.location = window.location;

      }

    }

  </script>

Step-4: Write the script-manager's AsyncPostBackError event:

protected void smBody_AsyncPostBackError(object sender, AsyncPostBackErrorEventArgs e)

{

smBody.AsyncPostBackErrorMessage = e.Exception.Message;

}

Now all the postback errors will be displayed in alert message and after that the page will be reloaded :-).

Thanks. :-)

.net Extension Menthod

Extension methods enable you to "add" methods to existing types without creating a new derived type or modifying the original type. Extension methods are a special kind of static method, but they are called as if they were instance methods on the extended type. There is no apparent difference between calling an extension method and actually defined methods of that type.

for example lets create an extension method for string type to check whether that particular string can be convert to int or not:

using System;
using System.ComponentModel;
using System.Reflection;
public static class Extension
{
    public static bool IsInt(this string str)
    {
        int iCount = 0;
        return int.TryParse(str, out iCount);
    }
}

And now we can use this static method to check whether a string can be converted to int or not:

string str1="a";

string str2="1";

    if(str1.IsInt())
    {
        Response.Write("string can be converted to int");
    }
    else
    {
        Response.Write("string can not convert to int");
    }

Few more Examples:

namespace ExtensionMethods
{
    public static class Extensions
    {
        public static int WordCount(this String str)
        {
            return str.Split(new char[] { ' ', '.', '?' }, StringSplitOptions.RemoveEmptyEntries).Length;
        }

        public static int ActualLength(this string[] strArray)
        {
            int iCount = 0;
            for (int i = 0; i < strArray.Length; i++)
            {
                if (strArray[i] != string.Empty && strArray[i] != null)
                    iCount++;
            }
            return iCount;
        }

        public static bool IsInt(this string str)
        {
            int iCount = 0;
            return int.TryParse(str, out iCount);
        }

        public static bool IsLong(this string str)
        {
            long iCount = 0;
            return long.TryParse(str, out iCount);
        }
        public static string GetEnumDescription(this Enum value)
        {
            FieldInfo fi = value.GetType().GetField(value.ToString());
            DescriptionAttribute[] attributes = (DescriptionAttribute[])fi.GetCustomAttributes(typeof(DescriptionAttribute), false);
            return (attributes.Length > 0) ? attributes[0].Description : value.ToString();
        }
    }
}

"asp.net, C#" Control '******_*******_*******' of type 'GridView' must be placed inside a form tag with runat=server.

        //Problem:
        "Control 'ctl00_cphBody_dgReport' of type 'GridView' must be placed inside a form tag with runat=server."

        protected void btnExcel_Click(object sender, System.EventArgs e)
        {
            System.IO.StringWriter stringWrite = new System.IO.StringWriter();
            System.Web.UI.HtmlTextWriter htmlWrite = null;
            Response.AddHeader("content-disposition", "attachment;filename=ActivatedUserDetails.xls");
            Response.Charset = "";
            Response.Cache.SetCacheability(HttpCacheability.NoCache);
            Response.ContentType = "application/xls";
            htmlWrite = new HtmlTextWriter(stringWrite);
            dgReport.RenderControl(htmlWrite);
            Response.Write(stringWrite.ToString());
            Response.End();
        }

        //Solution: Step-1:
        //on page.aspx page set EnableEventValidation to false

        EnableEventValidation="false"

        //on page.aspx page set EnableEventValidation to false

        //Solution: Step-2:

        //on page.aspx.cs page add the following code snippet.

        public override void VerifyRenderingInServerForm(Control control)

        {

        }

        //and its all done :-)

ajax post to post data to server and get response using jQuery and JSON.

1. Create a page PageName.aspx, create a div on that:
    <div id="target_div_id">  

    </div>

2. Include the jQuery file.
3. call the following javascript function on any event:

function JsonPost(input1, input2, input3, input4) {

        URL = "PageName.aspx/WebMethodName";

    var options = {

        type: "POST",

        contentType: "application/json; charset=utf-8",

        dataType: "json",

        url: URL,

        data: '{input1:"' + input1 + '", input2:"' + input2 + '", input3:"' + input3 + '", input4:"' + input4 + '"}',

        success: function (msg) {

            if (msg.d == 'error')

                alert(msg.d);

            else {

                $('#target_div_id').append(msg.d);

            }

            HideLoader();

        },

        error: function (msg) {

            alert(msg.d);

        }

    };

    $.ajax(options);

}
4. Following web method will automatically called:


    /// <summary>

    /// Create a web method, input parameter must be same as the parameters in our web method.

    /// from here we will have to return the complete html(including html controls, their ids and classes)

    /// </summary>

    /// <param name="input1"></param>

    /// <param name="input2"></param>

    /// <param name="input3"></param>

    /// <param name="input4"></param>

    /// <returns></returns>

    [WebMethod]

    public static string WebMethodName(string input1, string input2, string input3, string input4)

    {

        try

        {

            int j = 10;//some number depending upon our requirement

            StringBuilder sbResult = new StringBuilder();

            for (int i = 0; i < j; i++)

            {

                sbResult.AppendLine("<!--any required html containing controls and ids-->");

            }

            return sbResult.ToString();

        }

        catch (Exception ex)

        {

            return ex.Message;

        }

    }

Section Separators and Conditional Formatting

Section Separators and Conditional Formatting
Different formatting can be applied to a string based on whether the value is positive, negative, or zero. To produce this behavior, a custom format string can contain up to three sections separated by semicolons. These sections are described in the following table.
No. of Sections	Description
One section	The format string applies to all values.
Two sections	The first section applies to positive values and zeros, and the second section applies to negative values. If the number to be formatted is negative, but becomes zero after rounding according to the format in the second section, then the resulting zero is formatted according to the first section.
Three sections	The first section applies to positive values, the second section applies to negative values, and the third section applies to zeros. The second section can be left empty (by having nothing between the semicolons), in which case the first section applies to all nonzero values. If the number to be formatted is nonzero, but becomes zero after rounding according to the format in the first or second section, then the resulting zero is formatted according to the third section.
Section separators ignore any preexisting formatting associated with a number when the final value is formatted. For example, negative values are always displayed without a minus sign when section separators are used. If you want the final formatted value to have a minus sign, you should explicitly include the minus sign as part of the custom format specifier.

.NET Custom Number Format Strings

.NET Custom Number Format Strings
Specifier	Name	Description
0	Zero placeholder	If the value being formatted has a digit in the position where the '0' appears in the format string, then that digit is copied to the result string. The position of the leftmost '0' before the decimal point and the rightmost '0' after the decimal point determines the range of digits that are always present in the result string. The "00" specifier causes the value to be rounded to the nearest digit preceding the decimal, where rounding away from zero is always used. For example, formatting 34.5 with "00" would result in the value 35.
#	Digit placeholder	If the value being formatted has a digit in the position where the '#' appears in the format string, then that digit is copied to the result string. Otherwise, nothing is stored in that position in the result string. This specifier never displays the '0' character if it is not a significant digit, even if '0' is the only digit in the string. It will display the '0' character if it is a significant digit in the number being displayed. The "##" format string causes the value to be rounded to the nearest digit preceding the decimal, where rounding away from zero is always used. For example, formatting 34.5 with "##" would result in the value 35.
.	Decimal point	The first '.' character in the format string determines the location of the decimal separator in the formatted value; any additional '.' characters are ignored. The actual character used as the decimal separator is determined by the NumberDecimalSeparator property of the NumberFormatInfo that controls formatting.
,	Thousand separator and number scaling	Thousand Separator Specifier:If one or more ',' characters is specified between two digit placeholders (0 or #) that format the integral digits of a number, a group separator character is inserted between each number group in the integral part of the output. The NumberGroupSeparator and NumberGroupSizes properties of the current NumberFormatInfo object determine the character used as the number group separator and the size of each number group. Number Scaling Specifier:If one or more ',' characters is specified immediately to the left of the explicit or implicit decimal point, the number to be formatted is divided by 1000 each time a number scaling specifier occurs. For example, if the string "0,," is used to format the number 100 million, the output is "100". You can use thousand separator and number scaling specifiers in the same format string.
%	Percentage placeholder	The presence of a '%' character in a format string causes a number to be multiplied by 100 before it is formatted. The appropriate symbol is inserted in the number itself at the location where the '%' appears in the format string. The percent character used is dependent on the current NumberFormatInfo class.
E0 E+0 E-0 e0 e+0 e-0	Scientific notation	If any of the strings "E", "E+", "E-", "e", "e+", or "e-" are present in the format string and are followed immediately by at least one '0' character, then the number is formatted using scientific notation with an 'E' or 'e' inserted between the number and the exponent. The number of '0' characters following the scientific notation indicator determines the minimum number of digits to output for the exponent. The "E+" and "e+" formats indicate that a sign character (plus or minus) should always precede the exponent. The "E", "E-", "e", or "e-" formats indicate that a sign character should only precede negative exponents.
\	Escape character	In C# and C++, the backslash character causes the next character in the format string to be interpreted as an escape sequence. It is used with traditional formatting sequences like '\n' (new line). In some languages, the escape character itself must be preceded by an escape character when used as a literal. Otherwise, the compiler interprets the character as an escape sequence. Use the string "\\" to display '\'. Note that this escape character is not supported in Visual Basic; however, ControlChars provides the same functionality.
'ABC' "ABC"	Literal string	Characters enclosed in single or double quotes are copied to the result string, and do not affect formatting.
;	Section separator	The ';' character is used to separate sections for positive, negative, and zero numbers in the format string.
Other	All other characters	Any other character is copied to the result string, and does not affect formatting.

D or d	Decimal	This format is supported only for integral types. The number is converted to a string of decimal digits (0-9), prefixed by a minus sign if the number is negative. Precision specifier (eg. “{0:d3}” allowed.
E or e	Scientific (expol)	The number is converted to a string of the form "-d.ddd…E+ddd" or "-d.ddd…e+ddd", where each 'd' indicates a digit (0-9). The string starts with a minus sign if the number is negative. One digit always precedes the decimal point. Precision specifier (eg. “{0:E5}” allowed. The case of the format specifier indicates whether to prefix the exponent with an 'E' or an 'e'. The exponent always consists of a plus or minus sign and a minimum of three digits. The exponent is padded with zeros to meet this minimum, if required.
F or f	Fixed-point	The number is converted to a string of the form "-ddd.ddd…" where each 'd' indicates a digit (0-9). The string starts with a minus sign if the number is negative. Precision specifier (eg. “{0:f4}” allowed.
G or g	General	The number is converted to the most compact of either fixed-point or scientific notation, depending on the type of the number and whether a precision specifier is present.
N or n	Number	The number is converted to a string of the form "-d,ddd,ddd.ddd…", where '-' indicates a negative number symbol if required, 'd' indicates a digit (0-9), ',' indicates a thousand separator between number groups, and '.' indicates a decimal point symbol. The actual negative number pattern, number group size, thousand separator, and decimal separator are specified by the current NumberFormatInfo object. Precision specifier (eg. “{0:N5}” allowed.
P or p	Percent	The number is converted to a string that represents a percent as defined by the NumberFormatInfo.PercentNegativePattern property if the number is negative, or the NumberFormatInfo.PercentPositivePattern property if the number is positive. The converted number is multiplied by 100 in order to be presented as a percentage. Precision specifier (eg. “{0:p6}” allowed.
R or r	Round-trip	This format is supported only for the Single and Double types. The round-trip specifier guarantees that a numeric value converted to a string will be parsed back into the same numeric value. When a numeric value is formatted using this specifier, it is first tested using the general format, with 15 spaces of precision for a Double and 7 spaces of precision for a Single. If the value is successfully parsed back to the same numeric value, it is formatted using the general format specifier. However, if the value is not successfully parsed back to the same numeric value, then the value is formatted using 17 digits of precision for a Double and 9 digits of precision for a Single. Precision specifier NOT allowed.
X or x	Hexa decimal	This format is supported only for integral types. The number is converted to a string of hexadecimal digits. The case of the format specifier indicates whether to use uppercase or lowercase characters for the hexadecimal digits greater than 9. Precision specifier (eg. "{0:x4}" allowed. If required, the number is padded with zeros to its left to produce the number of digits given by the precision specifier.
Any other single char.	(Unknown specifier)	An unknown specifier throws a runtime format exception.

f	Represents the most significant digit of the seconds fraction. Note that if the "f" format specifier is used alone, without other format specifiers, it is interpreted as the "f" standard DateTime format specifier (full date/time pattern). When you use this format specifier with the ParseExact or TryParseExact method, the number of "f" format specifiers that you use indicates the number of most significant digits of the seconds fraction to parse.
ff…	Number of repeated specifiers represents most significant digits of the seconds fraction.
F	Represents the most significant digit of the seconds fraction. Nothing is displayed if the digit is zero. When you use this format specifier with the ParseExact or TryParseExact method, the number of "F" format specifiers that you use indicates the maximum number of most significant digits of the seconds fraction to parse.
FF…	Number of repeated specifiers represents most significant digits of the seconds fraction. Trailing zeros, or two zero digits, are not displayed.
g or gg	Represents the period or era (A.D. for example). This specifier is ignored if the date to be formatted does not have an associated period or era string.

tt	Represents the A.M./P.M. designator as defined in the current System.Globalization.DateTimeFormatInfo.AMDesignator or System.Globalization.DateTimeFormatInfo.PMDesignator property.
y	Represents the year as at most a two-digit number. If the year has more than two digits, only the two low-order digits appear in the result. If the year has fewer than two digits, the number is formatted without a leading zero.
yy	Represents the year as a two-digit number. If the year has more than two digits, only the two low-order digits appear in the result. If the year has fewer than two digits, the number is padded with leading zeroes to achieve two digits.
yyy	Represents the year as a three-digit number. If the year has more than three digits, only the three low-order digits appear in the result. If the year has fewer than three digits, the number is padded with leading zeroes to achieve three digits. Note that for the Thai Buddhist calendar, which can have five-digit years, this format specifier displays all five digits.
