c# - 鼠标右键选择单元格

Question

如何通过鼠标右键选择RadGridView中的单元格？

以下代码无效:

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;
    }
}

很奇怪，但是选择行可以正常工作:

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

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