Hi Furkan,

Are you dinamically creating and adding controls to the control tree? It
looks like some of your controls are not there when postback data is
processed.

Can't tell much by your posted code. At which point is it running? The
important thing is that you add the control to the control tree:

as early as possible in the page execution lifecycle (Init, Load)

If you're adding it in response to a click event or such then you're out of
luck as at that point the postback data has been already processed and your
control wasn't in the tree to receive it.
