I am added RadTreeNodes directly to the control. They are added like this...
I added PostBack and in the past NavigateUrl = "#", but with no result. The message telling me that an attempt to navigate away is happening in Chrome. As a side note, if I do ever click on the "Ok" button nothing happens.
new RadTreeNode(item.Name, item.Path){ ImageUrl = GetNodeImage(item.TypeName), ToolTip = item.Name, PostBack = false}
