Do not close ToolStripMenu on clicking in winforms

Question

I work on a c# winform project that the main toolstripmenu have not to be hide after user clicks on its item, how can I do that?

Answer 1

I found better answer on MSDN forum. Dropdown doesn't close on click, but closes in other cases:

DropDown.Closing += new ToolStripDropDownClosingEventHandler(DropDown_Closing);
...
private void DropDown_Closing(object sender,  ToolStripDropDownClosingEventArgs e)
{
    if (e.CloseReason == ToolStripDropDownCloseReason.ItemClicked)
    {
        e.Cancel = true;
    }
}
