Hi,
I have a master page that has a RadSplitter on it with 2 panes ... left and right. On the left pane I have a RadTreeView. On the right pane I have the content.

Most of the time I use a RadAjaxPanel or the RadAjaxManager. However, on the page I am having a problem with, I am using a FileUpload control which means no ajax.

As a result any postback and the tree disappears. If I remove the FileUpload and just have a button on the content page with no RadAjaxPanel the tree still disappears.

Any ideas?
Thanks ... Ed

Hello Ed Staffin,

Do you add the treeview from codebehind? If yes check whether you are adding it only on initial load of the page. If this is the case you should make sure the treeview is always created (on every load).
