[Solved] LoadOnDemand clears Checkboxes

[Michael]

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.

Hi Michael Sheppard,

I followed the article Inherit the the Checked state of the parent Node when loading Nodes on demand
and the checked state was propagated to the child nodes.

What is different in your case?
