ImageList.RecreateHandle Event

 

Occurs when the Handle is recreated.

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

[BrowsableAttribute(false)]
public event EventHandler RecreateHandle

You can use this event to do special processing when the Handle is recreated by actions such as changing the ColorDepth or ImageSize. Special processing may be required because setting the ColorDepth or the ImageSize property after setting the Images property causes the handle to be recreated and the images to be discarded.

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the RecreateHandle event. This report helps you to learn when the event occurs and can assist you in debugging. To report on multiple events or on events that occur frequently, consider replacing MessageBox.Show with Console.WriteLine or appending the message to a multiline TextBox.

To run the example code, paste it into a project that contains an instance of type ImageList named ImageList1. Then ensure that the event handler is associated with the RecreateHandle event.

private void ImageList1_RecreateHandle(Object sender, EventArgs e) {

   MessageBox.Show("You are in the ImageList.RecreateHandle event.");

}
