#VISUAL STUDIO MENUSTRIP MDI WINDOW LIST ITEM CODE#

The following code implements a reasonably generic approach that works even if you change the number of items in the menu or the variable name of the separator. The easiest solution is to handle the DropDownOpening and DropDownClosed events of the ToolStripMenuItem for the Window menu, and hide or show the separator as required. However, you don't want this separator to appear if there are no children, because it looks odd at the bottom of the menu. If you want to put additional options in the same menu that has the window list (for example, options to rearrange the windows, as you'll see in the next section), you'll probably want to add a separator between your items and the window list. There is no way to add other menu items after the list. To add an event handler, you go to Events window and double click on Click and other as you can see in Figure 6. For example, on File > New menu item click event handler, we may want to create a new file. ■Note The MDI window list is always added at the bottom of the menu. The main purpose of a menu item is to add a click event handler and write code that we need to execute on the menu item click event handler. The user also can use the menu to move from window to window, without any required code. Gets or sets the ToolStripMenuItem that is used to display a list of Multiple-document interface (MDI) child forms. Once you've established this link, the Windows Forms engine automatically adds one item to the bottom of the submenu for each child window (using the title bar for the menu text) and places a check mark next to the window that is currently active (see Figure 19-6). You can perform this step using the Properties window, which will give you a drop-down list of all the ToolStripMenuItem objects that are a part of the menu. Once you've created this menu item, set the MenuStrip.MdiWindowListItem to the top-level ToolStripMenuItem you created. Typically, this ToolStripMenuItem will display the text '&Window'. To create an MDI child window list, simply add a MenuStrip, and then insert one Tool-StripMenultem for the list. By convention, MDI applications often provide a menu that lists all the open document windows, and provides options for automatically tiling or cascading them.
