Hi.
I create a panel bar item, and attach ItemTemplate to it in the code-behind.
Everything looks ok, controls added to panel bar display just fine, but when i try to access them in code-behind (after a button on page being clicked) RadPanelITem that contains dynamically added controls doesn't show them anymore, its Controls collection is empty (but it's not empty after i add the controls) and findControl returns null.
What am i doing wrong?

My guess is that since template should be instantiated upon a postback, which happens when i click a button on the page, the contens of RadPanelItem is cleared. The question is, how can I access data entered in dynamically added controls when i click the abovementioned button?

Further research shows the following:
It doesn't really matter whether controls are added dynamically directly to radPanelItem, or created in InstantiateIn method of ItemTemplate which is assigned to radPanelItem mentioned above, the controls "won't be there" during postback.
Please, help.

Hi Yura,
In general the template controls could be accessed as shown in the following help article here. Please note that in case a ContentTemplate is used the template controls could be access directly by ID.
