Question

I’ve assigned a contextMenuStrip to the same contextual menu property of two ListBox controls.
I would like to determine which of them has activated the contextual menu.
Because I have to change some entries depending on which control was clicked at runtime.

        private void copyNotesToClipboardStripMenu_Click(object sender, EventArgs e)
        {
            ListBox cntrl = conMenuNotes.SourceControl as ListBox;
            //cntrl does not contain info about which ListBox was clicked :((

            //check which ListBox was clicked
            if (/*oneListBox*/)
            {
                 //do something                    
            }
            if(/*anotherLiskBox*/)
            {    
                //do something
            }              
        }

As i read another posts it should be the name of the clicked control in the Label property.

I see that cntrl.Label is null

What i’m doing wrong ?
Advice me how to resolve this ambiguity.
Thank you!

I found a result that works fine for me

        private void copyNotesToClipboardStripMenu_Click(object sender, EventArgs e)
        {
            ToolStripMenuItem menuItem = sender as ToolStripMenuItem;
            if (menuItem != null)
            {
                ContextMenuStrip calendarMenu = menuItem.Owner as ContextMenuStrip;
                if (calendarMenu != null)
                {
                    Control controlSelected = calendarMenu.SourceControl;
                }
            }
        }

The property Name of controlSelected object contains the name of control which has activated the contextual menu.
