I have a RadGridView where I would like the following behavior:
- only 1 or 0 rows can be selected at any given time
- if I click on a row that is unselected, the row will become the only row selected
- if I click on a row that is already selected, the row will become deselected

This type of selection seems to be somewhere between the Single SelectionMode (in that only one row can be selected at once) and the Multiple SelectionMode (in that a row can be deselected by clicking on it).

Is there an easy/clean way to do this?

Hello Geoff Hardy,

Here is what you can do - set the SelectionMode to Multiple and subscribe to the SelectionChanged event and define its handler as follows:

private void clubsGrid_SelectionChanged(object sender, SelectionChangeEventArgs e)
{
    if (clubsGrid.SelectedItems.Count > 1)
    {
        Club latestAddedItem = e.AddedItems[0] as Club;
        clubsGrid.SelectedItems.Clear();
        clubsGrid.SelectedItems.Add(latestAddedItem);
    }
}

Hope this helps.

All the best,
