How to: Create an MDI Form with Menu Merging and ToolStrip Controls
The System.Windows.Forms namespace supports multiple document interface (MDI) applications, and the MenuStrip control supports menu merging. MDI forms can also ToolStrip controls.
There is extensive support for this feature in Visual Studio.
For more information, see Walkthrough: Creating an MDI Form with Menu Merging and ToolStrip Controls and Walkthrough: Creating an MDI Form with Menu Merging and ToolStrip Controls and Walkthrough: Creating an MDI Form with Menu Merging and ToolStrip Controls and Walkthrough: Creating an MDI Form with Menu Merging and ToolStrip Controls.
Example
The following code example demonstrates how to use ToolStripPanel controls with an MDI form. The form also supports menu merging with child menus.
