[Solved] prevent display of empty gridview

[Carl]

Hi,

I have a hierarchical grid with 4 levels, but in practice right now we are using 2.  However, even when the bound item to the grid contains a reference to an empty or null collection, an extra empty row shows up with an expander button on the left.  How can I control the grid so that the expander button is not present when there are no children to the row?

Thanks,

Carl

Never mind.  I found that I can control this through the RowLoaded  and

RowIsExpandedChanging events
