Gets the index value of the item that is being drawn.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
The following example demonstrates how to create owner-drawn ListBox items. The code uses the DrawMode property to specify that the items drawn are a fixed size and the DrawItem event to perform the drawing of each item into the ListBox. The example code uses the properties and methods of the DrawItemEventArgs class passed as a parameter to the event handler to draw the items. This example assumes that a ListBox control named listBox1 was added to a form and that the DrawItem event is handled by the event handler that is defined in the example code. The example also assumes that items were added to the ListBox with the text of "Apple", "Orange", and "Plum", in that order.
