Issue 1:
I get an error on a heirarchical gridview:

An unhandled exception of type 'System.Reflection.TargetInvocationException' occurred in mscorlib.dll
Additional information: Exception has been thrown by the target of an invocation.

I have not been able to properly establish what causes this error, but I can see that it comes when I click on the child rows. The error is somewhat sporadic but it is always after expanding and clicking on childrows. The childrows in my grid are readonly.

Issue 2:
When I double click on childrows, the grid sometimes automatically scrows to the bottom (i.e. to the last row in the gridview mastertable) and I cannot explain this behaviour.

Issue 3:
I have observed yet another error.. see below (couldnt attach it as a *.txt):

Are you loading your grid on a different thread / background worker? 
If so, then ensure that you are not trying to update the UI from the background worker.

Hi, 

I'm finding more and more issues with hierarchy grids in this new release. Can you post your load and populate grid methods here?

Eddie, we have not observed this issue before. Therefore could you please open a new support ticket and send me your application describing the exact steps to reproduce the issue? This will help me to identify the reason for the wrong behavior and find a proper solution. 

Richard, we have encountered some issues related with our save/load functionality. Please specify the exact situation where the issue occurs.

Best wishes,
Jack

Hi Jack, 

The issues Im getting arent related to Save/Load layout. (we have removed our save/load layout functionality until SP2 is released) I have already opened a support ticket for some display issues in hierarchy grids. I have been advised that GridView.MasterTemplate.Refresh() should get around the display issues which I though also might help here.
