Select cell by right mouse click

Question

How to select cell in RadGridView by right mouse click?

The following code doesn't work:

private void RadGridView_PreviewMouseDown(object sender, MouseButtonEventArgs e)
{
    // ... getting grid and cell
    if (e.RightButton == MouseButtonState.Pressed)
    {
        grid.UnselectAll();
        grid.CurrentCellInfo = new GridViewCellInfo(cell);
        cell.IsCurrent = true;
        cell.IsSelected = true;
    }
}

It's strange, but selecting row works fine:

if (e.RightButton == MouseButtonState.Pressed)
{
    grid.UnselectAll();
    row.IsSelected = true;
    row.IsCurrent = true;
}

Maybe you have code that deselects cells that gets called just after the selection ? — franssu, Aug 23 '12 at 13:20
I've checked it (( This only one place where I select/deselect cells. — Rover, Aug 23 '12 at 13:21
.. and if you remove grid.CurrentCellInfo = new GridViewCellInfo(cell); ? — franssu, Aug 23 '12 at 13:24
The same result. Switch IsSelected and IsCurrent - same. Remove IsCurrent - same. — Rover, Aug 23 '12 at 13:25
Have you ever managed to select a cell by the past ? Maybe the cell is selected but you get no feedback ? — franssu, Aug 23 '12 at 13:26

if (e.RightButton == MouseButtonState.Pressed)
{
    grid.Focus();
    grid.UnselectAll();
    grid.CurrentCellInfo = new GridViewCellInfo(cell);
    grid.SelectedCells.Add(grid.CurrentCellInfo);
}

Did you try grid.SelectionMode = Telerik.WinControls.UI.GridViewSelectionMode.CellSelect ?

Use the OriginalSource the get the Cell that was clicked (remember that can also be null) and set the IsSelected value.
