Hi Squish,
Thank you for your interest in Syncfusion products.
You need to handle QueryCellStyleInfo event and set the height of GridGroupingControl to achieve this task. Please refer the below code snippet for more detais.
void gridGroupingControl1_QueryCellStyleInfo(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableCellStyleInfoEventArgs e)
{
rowcount = this.gridGroupingControl1.TableControl.Model.RowCount;
this.gridGroupingControl1.Height = (rowheight * rowcount);
}
Here is the minimal sample which implements this task.
