I have used GridGroupingControl with the parent-child data tables in the DataSet.

Now I am looking for the ways to work with it in "virtual mode" via OnQueryCellInfo/OnQueryRowCount. Can you please advise how to do that or provide a sample?

Many thanks!

Hi Shakhrukh,
Thanks for your interest in Syncfusion Products.

The way GridControl implements virtual mode is different than GridGroupingControl. QueryCellInfo/QueryRowCount events are handled when implementing virtual mode using GridControl. Please refer the dashboard sample to understand and implement the working of virtual mode in GridGroupingControl.

Aslo, you may refer to forum link for more details :
