Hello,

i've got a simple problem.

if you want to deselect an selected row you have to press ctrl while you click. this is to less intuitiv in our case. i want it make it possible to deselect with a simple click on a row allready selected. the tree is always single-selected.

how can i do that?

thanks
egl

You would need to derive a new class from Virtual Tree and override the SelectRow method as follows:

Code:
protected override void SelectRow(Row row)
{
    if (row.Selected)
    {
        if (AllowSelectionChange(row, row, SelectionChange.Clear))
        {
             SelectedRows.Clear();
        }
    }
    else
    {
        base.SelectRow(row);
    }
}
