How to deselect all selected rows in a DataGridView control?

Question

I\'d like to deselect all selected rows in a DataGridView control when the user clicks on a blank (non-row) part of the control.
How can I do this?

Answer 1

In VB.net use for the Sub:

    Private Sub dgv_MouseUp(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles dgv.MouseUp
    ' deselezionare se click su vuoto
    If e.Button = MouseButtons.Left Then
        ' Check the HitTest information for this click location
        If Equals(dgv.HitTest(e.X, e.Y), DataGridView.HitTestInfo.Nowhere) Then
            dgv.ClearSelection()
            dgv.CurrentCell = Nothing
        End If
    End If
End Sub
