How to show ContextMenuStrip in a grid cell in the edit mode in WinForms GridControl?

Show context menu strip

In WinForms GridControl, by default, the ContextMenuStrip opens only on right-click over the associated control. When the cell is in edit mode, it no longer receives mouse-related events. The control (TextBox or ComboBox) present in the cell alone receives the mouse events. So, to have a ContextMenuStrip in the edit mode, you need to set the ContextMenuStrip for those controls present in the cell. This can be achieved by handling the events CurrentCellControlGotFocus, CurrentCellControlLostFocus, and MouseDown.

void gridControl1_CurrentCellControlLostFocus(object sender, ControlEventArgs e)
{
    e.Control.MouseDown -= new MouseEventHandler(Control_MouseDown);
}

void Control_MouseDown(object sender, MouseEventArgs e)
{
    if (e.Button == MouseButtons.Right)
      this.contextMenuStrip1.Show(Control.MousePosition.X, Control.MousePosition.Y);
}

void gridControl1_CurrentCellControlGotFocus(object sender, ControlEventArgs e)
{
    e.Control.MouseDown += new MouseEventHandler(Control_MouseDown);
}

Private Sub gridControl1_CurrentCellControlLostFocus(ByVal sender As Object, ByVal e As ControlEventArgs)
      RemoveHandler e.Control.MouseDown, AddressOf Control_MouseDown
End Sub

Private Sub Control_MouseDown(ByVal sender As Object, ByVal e As MouseEventArgs)
    If e.Button = MouseButtons.Right Then
 Me.contextMenuStrip1.Show(Control.MousePosition.X, Control.MousePosition.Y)
    End If
End Sub

Private Sub gridControl1_CurrentCellControlGotFocus(ByVal sender As Object, ByVal e As ControlEventArgs)
  AddHandler e.Control.MouseDown, AddressOf Control_MouseDown
End Sub
