Load on demand

[Gabe]

Hi,
  I was wondering if there is a way to implement a "load on demand" pattern using RadTreeListView?  I noticed that the feature is included with RadTreeView:

But I cannot find any documentation related to it for RadTreeListView.

Thanks,

Hi Yordanka,
  Thank you for the prompt response.  I had previously tried to use this RowIsExpandedChanged event, however, it does not appear to ever be called.  Being concerned that I did not configure the control correctly, I created an application using the code in the getting started tutorial, and indeed it appears to suffer from the same issue.  In order to reproduce this issue you can run the code from the getting started tutorial, just add a RowIsExpandedChanged handler and put a breakpoint in it, I am never seeing this breakpoint being hit.  I am referencing telerik controls version 2010.2.812.35.  All work was completed in Visual Studio 2008.

Thanks,
-Gabe

Hi Gabe,

We can confirm that we had an issue with RowIsExpandedChanged  in Q2 2010 SP1 version - the one pointed by you. But, it was fixed with the next official release - Q2 2010 SP2 (.0924). Is it possible to you to upgrade to this version or to our latest official version - Q3 2010 SP1 (.1314) so that you would be able to implement Load on demand approach ?
 
Kind regards,
