Checking if a cell is selected

When someone clicks on a cell, i need to check whether the cell is selected (in the CellClick event). How can i do this.
Thanks,
Julie

Actually it seems like CellClick is too late since clicking on an unselected cell automatically selects it. I need to write code to unselect it if selected. By the time CellClick fires there's no way to tell if the user clicked on a selected cell, or if the cell was unselected and automatically selected.

I tried using the SelectionChanging event to set a flag, but it doesn't seem to be firing reliably, or able to tell reliably whether the cell is selected before the user clicks on it with ctrl+left mouse.

What is the best way to know the selected state of the cell when the user clicks on it (Ctrl+Mouse).

Thanks,
Julie

Hi Julie,

In both GridControl and GridDataBoundGrid classes, there is a member Selections which you can use to access exactly what cells are selected in the grid. This Selections class has a GetSelectedRows method that returns an array of ranges that are selected row ranges. You can then use the Contains method on the the array to see if a particular row range is in the array. Below are code snippets that test whether row 2 is selected.

if (this.gridDataBoundGrid1.Selections.GetSelectedRows(true, false).Contains(GridRangeInfo.Row(2)))
{
Console.WriteLine("Row 2 is selected");
}


Please let me know if this helps.

Regards,
Jisha

Thanks for your response. What is the best event to use to check this? CellClick seems too late.

I think i got it working in the SelectionChanging event using the following to set a flag which i check in the CellClick event.
if (this.Model.Selections.Ranges.AnyRangeContains(e.Range))
{ this.m_bRemoveRange = true;
}
Do you see anything wrong with this approach?

Thanks,
Julie

Yes. You can also use SelectionChanging event. Let us know if you find any difficulties.
