Hi,

It's not really clear what is your problem. From your question, it looks like you already understand the matter and how to solve the problem.

Please see Solution 1. First links shows the example of working with ViewState for keeping control states...

Thanks for your reply, i have test the example in first url, Custom properties are preserved on postback, but in this case my ascx have other controls like panels, textbox, buttons if i set panel.visible = false; this is not preserved on postback, as i said before this ascx is inside a custom compositecontrol.

What's the difference? You should expose the "inside" property to the composite control (actually, create a new property and implement its accessors using the inside property), and then use this new property in exact same way as any other one.
