Hi Developers,
following is the complete single code to filter large list of checkboxes and radiobuttons. I created a hashtable and bind that to radiobuttonlist and checkboxlist. we can use any data source(collection, dataset, datatable etc) instead. same code will work with other data listing controls(repeater, datalist and gridview).
