Hi, i hope, any could help me

In my primary page I have a User Control embedded, inside of an UpdatePanel, this user control shows a WebDataGrid, some filters and a "Search" button.

This WebDataGrid, which is inside another UpdatePanel, has a pager, Now..

When i click the "Search" Button, the grid fills perfect but when PageIndexChanged event fires, the grid set to blank and that's it.

Right after that, if i click the "Search" Button again, the Grid fills with the Data, and pointing to the new Page Index.

My problem is... why it goes blank on the PageIndexChanged event?

Plz help, i'm on a hurry!

If you need some code, i can provide it

Thanks in advance
