This should more or less just work. Here is a little sample that adds a new row every 3/5 sec and it shows up OK in the GridGroupingControl. What are you doing differently? http://www.syncfusion.com/Support/user/uploads/GGC_NewRows_4fc69f0a.zip

Here is a sample with 3 tables nested. http://www.syncfusion.com/Support/user/uploads/GGC_NewRows_54cca4f0.zip

and, the records are being added on another thread, then acceptchanges is called.

You need to make sure that you only interact with the grid on the thread that created it. If you can upload a sample project showing the problem we can try to debug it here.

If you can upload a sample project showing the problem we can try to debug it here. hi, yes the grid is on its own thread. however the data gets added to the dataset on another thread. the design of the app keeps UI and data threads separate. the dataset is hiearchical 4 levels deep and is updated dozens of times a second. do you see any problems with this? the DS has thousands of records. this is also causing performance issues in the grouping control. can the GDBC work in this scenario? Is there a hiearchical virtual grid for this scenario?

I think this should work using version 3.3. Here is the sample modified to add the new rows on a background thread. http://www.syncfusion.com/Support/user/uploads/GGC_NewRows_e45b7a69.zip
