I am using the ajax rad treeview control.  I am loading treeview nodes on-demand using the serversidecallback property.  The treeview control is in a radupdatepanel.  I am using checkboxes.  When a user expands a node I evaluate whether the node is checked or not in a BuildRADDeptNode Method.  If  it is checked then the new sub-nodes are checked as well.

The problem is that no matter what the parent nodes state is when it is expanded it also gets passed to the event as a checked = false.  This is a real problem.
 

 

protected void RadTree1_NodeExpand(object o,RadTreeNodeEventArgs e)

{

 

 

    RadTreeNode nodeClicked = e.Node;

    BuildRADDeptNode(nodeClicked);

    pnlDeptTree.Visible = true;  

}

Please advise.
