ComboBox.MeasureItem Event

Occurs each time an owner-drawn ComboBox item needs to be drawn and when the sizes of the list items are determined.

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

member MeasureItem : IEvent<MeasureItemEventHandler,
    MeasureItemEventArgs>

You can create an event handler for this event to specify the size an item is made before it is drawn in the DrawItem event.

For more information about handling events, see Handling and Raising Events.

The following code example demonstrates how to create an owner-drawn combo box by setting the DrawMode property to OwnerDrawnVariable and handling the DrawItem and MeasureItem events. It also demonstrates setting the DropDownWidth and DropDownStyle properties. To run the example, paste the following code in a form. Call the InitializeComboBox method in the form's constructor or Load event.
