I manually set IsExpandable for the various nodes in my tree in the RowLoaded event based on some criteria that I determine at runtime.  When I have EnableRowVirtualization set to True and I scroll to an item that is initially not visible, the IsExpandable property is being set correctly, but the expand/collapse image is NOT being shown next to my row.  When I turn OFF EnableRowVirtualization, everything seems to work properly.  Anyone else seeing this?

Hi Thomas Whittaker,

We are familiar with a similar issue related to IsExpandable property but unfortunately we are still not able to provide a solution. To be sure that your problem is the same please send us a sample project or give us some more details how the IsExpandable property is set. To attach a sample project you need to open a support ticket. Thank you.
