Hi Pankaj,
Thanks for the interest in Syncfusion Grid.
GridControl1.clear() is used to clear the contents of the selected cells. You can use ClearCells to Clear the cells of the Grid. Please refer the following code snippet that shows how we can clear the cells of the Grid.
private void button1_Click(object sender, EventArgs e)
{
this.gridControl1.Model.ClearCells(GridRangeInfo.Table(), true);
}
Please refer the sample in the below link that illustrates the above.
