WinForms RadGridView - Deselecting all rows when user clicks on empty area

[Paolo Ascari]

Hi,

What's the best approach to deselect all rows of a WinForms RadGridView when the user clicks on the empty (i.e. blank) area of the containing grid?

(Using RadGridView Q1 2012)

Thanks in advance,
Paolo

Hello,

This should work for you.

this.radGridView1.MouseClick += new MouseEventHandler(radGridView1_MouseClick);

void radGridView1_MouseClick(object sender, MouseEventArgs e)
{
    if (this.radGridView1.ElementTree.GetElementAtPoint(e.Location).GetType() == typeof(GridTableElement))
    {
        this.radGridView1.ClearSelection();
        this.radGridView1.CurrentRow = null;
    }
}

Hope that helps
Richard

Hi Richard, works a treat!

I've changed it to use MouseDown instead of MouseClick.
One difference is that, for example, a click-and-drag on a scrollbar releasing the button on the empty area would also trigger a deselection, which is unintended in this case. This is because the mouse Location for the MouseClick event is determined at the 'mouse up'.

Thanks a lot for your help,
Paolo
