ToolTip.Draw Event

Occurs when the ToolTip is drawn and the OwnerDraw property is set to true and the IsBalloon property is false.

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

member Draw : IEvent<DrawToolTipEventHandler,
    DrawToolTipEventArgs>

With the Draw event, you can customize the appearance of the ToolTip.

The Draw event is raised by the ToolTip class when the ToolTip is drawn and the ToolTip.OwnerDraw property value is true and the IsBalloon property is false. The DrawToolTipEventArgs class contains all the information needed to paint the ToolTip, including the ToolTip text, the Rectangle, and the Graphics object on which the drawing should be done. To customize the look of the ToolTip, use the Rectangle to determine the bounds of the ToolTip, and the Graphics object to perform your customized drawing. You can increase the bounds of the ToolTip before it is shown by handling the Popup event.

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

The following code example demonstrates how to custom draw the ToolTip. The example creates a ToolTip and associates it to three Button controls located on the Form. The example sets the OwnerDraw property to true and handles the Draw event. In the Draw event handler, the ToolTip is custom drawn differently, depending on what button the ToolTip is being displayed for as indicated by the DrawToolTipEventArgs.AssociatedControl property.
