Hi Paurnima,
Thank you for your interest in Syncfusion products.
If you want to remove the multiple selected child record from parent table in a grid, you can use the “DeleteAll()”method. Please refer the below code,
Code:
private void btnDeselectAll_Click(object sender, EventArgs e)
{
foreach (Table tbl in this.gridGroupingControl1.Table.RelatedTables)
tbl.SelectedRecords.DeleteAll();
}
Please let us know if you have any concern.
Regards,
Muthukumar K
