I think at RadPanel (that is, Left Panel 1) which add a TreeView and its nodes, when loading the initial page load time can show TreeView and its nodes, but when I click the Left Panel 2, and then click the Left Panel 1 time They can no longer see the TreeView and its nodes, This is Why?
How can I add to put RadPanel in TreeView? And to make it always show?
Thanks!
