checkbox is checked but after filter why unchecked in asp.net

Question

when checkbox is checked but after filter why unchecked in asp.net using telerik grid filter using telerik radgrid.

Answer 1

When you do filter you must be doing a postback and at the same time the  checkbox is also doing the postback (firing the Checked/Changed event) (guessing your Checkbox's IsPostback property is set to true) causing the checkbox unchecked.

To overcome this you need to again set the checkbox after doing the filtering.
