I have 2 UltraPictureBox. ultraPictureBox1 and ultraPictureBox2.  I added to the property ContextMenuUltra a PopupMenuTool from the UltraToolBarManager.
At both PictureBoxes it’s the same PopupMenuTool. (I have only 1 PopupMenuTool)

In the ToolClick event, how can I get out on wich PictureBox the PopupMenu was clicked?
private void ultraToolbarsManager1_ToolClick(object sender, ToolClickEventArgs e)
{

}
