How to: Add ToolStrip Items Dynamically
You can dynamically populate the menu item collection of a xref:System.Windows.Forms.ToolStrip control when the menu opens.
Example
The following code example demonstrates how to dynamically add items to a xref:System.Windows.Forms.ContextMenuStrip control. The example also shows how to reuse the same xref:System.Windows.Forms.ContextMenuStrip for three different controls on the form.
In the example, an xref:System.Windows.Forms.ToolStripDropDown.Opening event handler populates the menu item collection. The xref:System.Windows.Forms.ToolStripDropDown.Opening event handler examines the xref:System.Windows.Forms.ContextMenuStrip.SourceControl%2A?displayProperty=nameWithType and xref:System.Windows.Forms.ToolStripItem.OwnerItem%2A?displayProperty=nameWithType properties and adds a xref:System.Windows.Forms.ToolStripItem describing the source control.
