On one form I have check box, label, dropdown, 3 buttons, 3 text boxes.

On one place I set values for them.

On submit label looses its text, buttons looses captions, dropdown looses all its items but check box and text boxes have their values still on them.

I checked all IsPostback options. They are all treated same way on same places but behaves differently.

Anybody have some option?

I think the problem is in your code on line 42, you are setting x equal to 1 when it has been initialized yet. That's what my crystal ball that magically shows me all of your code is telling me ...it doesn't always work that well, though. If that's not it, maybe try providing some actual code/details ?

Just dumping all of your code onto the page is almost as bad as providing no information! How about at least highlighting where the problems are occurring, or omitting parts that aren't relevant to the problem? That process is actually something that you should be doing on your own, anyway, even if you aren't asking someone else for help, since it is a valuable and important thing to do when going through a trouble-shooting or debugging process.

Anyway:

>>On submit label looses its text, buttons looses captions, ...
I see that one button has EnabledViewState=True, the others don't. Did you try enabling viewstate for the buttons and labels that are losing their values ??


>> dropdown looses all its items but check box and text boxes have their values still on them.

I don't even see any DropDownLists on your page anywhere ...

Yeah... my mistake. I switched drop down with text box to see will it have View State preserved and it did. It mean that drop down does not hold view state for some reason and text box do.

In method FillData() I set values to all controls on page. If I do save without required value I get error handled message and those conrols are not populated. If I do save with all correct entered values I get error that drop down do not have SelectedValue. This lines I pasted behave the same way just there is no drop down. Labels loose their text values and buttons their captions. I still have not found solution.

Thanks for trying to help.
