Answer 1

Try using click event of a LinkButton, instead of OnItemCommand . You can access LinkButton using below code in Click Event.

LinkButton lb = (LinkButton)Sender;

OR

LinkButton lb = Sender as LinkButton;

Answer 2

Dear Expert After 2 day finally i figure out why my page doesn't post back. after i tried to post back my button manually with java script and i failed. i tried to trace the script and i found this Error with firebug:

 TypeError: theForm.submit is not a function
     theForm.submit();

when i google it i found i have a button in my MasterPage with id="Submit" and as "submit is not a function" means that you named your submit button or some other element submit. Rename the button to btnSubmit and your call will magically work.

When you name the button submit, you override the submit() function on the form.

So This Problem Resolved. Thanks to all.
