Walkthrough - CommandButton with sub button and context menu

Glossary Item Box

This walkthrough describes how to create a CommandButton with a subordinate button. A context menu is displayed when the sub button is clicked. The context menu is used to select from a number options. Pressing the main section of the CommandButton is equivalent to clicking on the sub button and selecting the default menu option, which in this case is the New document item. The CommandButton and menu are shown below.

  1. Add a ContextMenuStrip to the Form.
  2. Add the items displayed in the image above to the menu.
  3. Drag a CommandButton onto the Form.
  4. Set the Name of the CommandButton to buttonNew.
  5. Set the Colour properties of the CommandButton as shown below.

  6. Set  the Menu property of the CommandButton to the ContextMenuStrip.
  7. Double click the CommandButton to add a Click event handler.
  8. Implement the CommandButton and ToolStripMenuItem Click event handlers as shown below.
