Grouped GridDataControl Error

[Yunus Aydogmus]

Hi,

Our problem is about WPF grouped GridDataControl. On update grouped GridDataControl by different thread cause exception like that "InvalidOperationException : The calling thread cannot access this object because a different thread owns it."
When i test same grid with grouping feature off, that works correctly.

Is there any solution except, synchronizing our worker thread with main UI thread?

Kindly,
Yunus AYDOGMUS

Hi Yunus,

For grouping to be done in a perfect manner you have to set the MappingName to the VisibleColumns and Check whether the AutoPopulateColumns is set to false if you have Used the VisibleColumn in our grid. This would cause the issue while grouping.
Could you please provide us with a simple sample regarding this issue to be reproduced, it would be helpful for us to provide the clear solution.
