Instead of getting control with dynamic name.Simply make it ClientIdMode=Static in your textbox control.this will fix your problem..Beware of this will create some ajax issues.

Shradha Kale · Answer

I even tried this but it dosen't solve my problem..I want to check whether the textbox is are empty or not.

Saineshwar Bageri · Answer

Sample check The error is here: var fdate = document.getElementById('txtFromDate'); var edate = document.getElementById('txtToDate'); The problem is that txtFromDate and txtToDate are the server name of controls not the client name (look the source of page from the browser). Try this: var fdate = document.getElementById(' '); var edate = document.getElementById(' ');
