DrawItemEventHandler Delegate

Represents the method that will handle the DrawItem event of a ComboBox, ListBox, MenuItem, or TabControl control.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

type DrawItemEventHandler = 
    delegate of 
        sender:Object * 
        e:DrawItemEventArgs -> unit

Parameters

sender
Type: System.Object
The source of the event.
e
Type: System.Windows.Forms.DrawItemEventArgs
A DrawItemEventArgs that contains the event data.

When you create a DrawItemEventArgs delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event handler delegates, see Events and Delegates.

The following code example demonstrates a menu with an owner-drawn menu item. This example uses the AddHandler statement and the AddressOf operator to designate a delegate to handle the MenuItem.DrawItem event. To run the example place paste it in a form that imports the System, System.Windows.Forms, and System.Drawing namespaces. Ensure all events are associated with their event-handling methods.
