Gridview edit button is firing only once

Hi everyone. Maybe someone have the solution for my probleme. I have a gridview with different columns. One of them is for thye edit button which display a popup details view. Everything works fine the first time I click on the edit button. But if I click again on the same or another edit button, nothing happens. The debugger says nothing. All the variable seems to pass without issues. I don't know what to do to solve my issue. Is someone has a idea ? Thank in advance

Accepted answer
your code does not call the postback event. Check if you are using Updatepanel. If you are using update palen, then use for the grid view event.

Check with break point, does post back event is done.

Let me know then, i will give suggestions

Thanks for your help Sundar. I found what was going on. In the save button of the panel, instead of hiding the modalpopuextention I was hidding the popup's panel. What a d.... I am. lol
