Hi all
We have a PanelBar with some nested treeviews which are created programmatically, i.e. at runtime in the code behind. The items in the PanelBar are dynamically created as well. Unfortunately when a postback occurs, the TreeViews just disappear.
The code of Page_Load is basically:
if (!IsPostBack)
{
BuildNavigation();
}
The result of calling BuildNavigation() also in a postback would be that the PanelBarItems appear twice, so this is not the solution.
How can I make shure that the TreeViews are generated also in the postback?
Thank you!

Hello Marc,
You need to create the treeviews in every page load. Since the items of the panelbar will duplicate you can first call:
RadPanelBar1.ClearSelectedItems();
RadPanelBar1.Items.Clear();
And then add the panelbar items.
