upgrade to VS 20081/19/2008 3:25:27 AM

1

I upgraded a project from 2005 to 2008.  One several of my forms I host a TreeView control.  Whereas before, using an IHierarchicalDataSource down to IHierarchyData, if I return false from HasChildren the TreeView shows the node as a leaf as opposed to having the ability to expand. 

In 2008, even though I return false from HasChildren, it shows the leaf node with the expansion icon.  Of course clicking to expand throws an error.  Is this a bug with the TreeView or am I doing something wrong in the new 2008 way of doing things?

I also have the following property in the aspx markup: ShowCheckBoxes="Leaf".  Consequently, since the control does not recognize the node as a leaf, it doesn't display the CheckBox.

 Please advise.

 Thank you.

Disregard, it has nothing to do with the upgrade.  I set the PopulateOnDemand property of the child nodes to True.  That's what caused the issue.
