How to: Set Up Automatic Menu Merging for MDI Applications
The following procedure gives the basic steps for setting up automatic merging in a multiple-document interface (MDI) application with MenuStrip.
To set up automatic menu merging
-
Create the MDI parent form by setting its IsMdiContainer property to true.
-
Add a MenuStrip to the MDI parent, setting its MainMenuStrip property to that MenuStrip.
-
Create an MDI child form, and set its MdiParent property to the name of the parent form.
-
Add a MenuStrip to the MDI child form.
-
On the child form, set the Visible property of the MenuStrip to false.
-
Add menu items to the child form's MenuStrip that you want to merge into the parent form's MenuStrip when the child form is activated.
-
Use the MergeAction property on the menu items in the child form's MenuStrip to control how they merge into the parent form.
