Coverd Cell

I have few header cells (both in row and column) as covered cell. I need help to achieve the following. If a user click on one of the covered cell in column or row header I need to select all the column (based on covered cell) or all the rows (based on covered cell). Let me try putting an example: this.programGrid.Model.CoveredRanges.Add(GridRangeInfo.Cells(0,1,0,2)); this.programGrid.Model.CoveredRanges.Add(GridRangeInfo.Cells(0,5,0,7)); So if they click either on column 1 or 2 it should select both (1,2) columns. If they click one on the 5,6 & 7 column then it should select all three(5,6,7) columns. I think it should be doable but need little direction. Thanks

You can handle the SelectionsChanging event and adjust e.Range if the selection intersects a coveredcell. Here is a try at this.
private void gridControl1_SelectionChanging(object sender, GridSelectionChangingEventArgs e)
{
	if(!e.Range.IsEmpty && e.Range.IntersectsWith(GridRangeInfo.Row(0)))
	{
		GridRangeInfo range = e.Range.IntersectRange(GridRangeInfo.Row(0));
		range = this.gridControl1.CoveredRanges.FindRange(0, range.Left);
		if(!range.IsEmpty)
			e.Range = GridRangeInfo.Cols(range.Left, range.Right);
	}
}

Thanks. It is working except that it does not select “First” cell. If covered range is (0,5,0,7) then does not matter where I click (on column 5,6 & 7) it does not select cell[0,5]. I would appreciate your reply! Thanks

This is by design. When you select a range of cells, the current cell is not selected. If you do not want this behavior, you can handle CurrentCellActivating and cancel it if you are trying to activate a header cell.
private void gridControl1_CurrentCellActivating(object sender, GridCurrentCellActivatingEventArgs e)
{
	if(e.RowIndex == 0)
		e.Cancel = true;
}
