Examples

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the ListBox.DrawItem event. This report helps you learn when the event occurs and can assist you in debugging.

To run the example code, paste it into a project that contains an instance of type ListBox that is named ListBox1. Then make sure that the event handler is associated with the ListBox.DrawItem event.

private void ListBox1_DrawItem(Object sender, DrawItemEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "BackColor", e.BackColor );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Bounds", e.Bounds );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Font", e.Font );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ForeColor", e.ForeColor );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Graphics", e.Graphics );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Index", e.Index );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "State", e.State );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "DrawItem Event" );
}

Private Sub ListBox1_DrawItem(sender as Object, e as DrawItemEventArgs) _ 
     Handles ListBox1.DrawItem

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "BackColor", e.BackColor)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Bounds", e.Bounds)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Font", e.Font)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "ForeColor", e.ForeColor)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Graphics", e.Graphics)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Index", e.Index)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "State", e.State)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"DrawItem Event")

End Sub

Remarks

If the item's state is DrawItemState.Selected, the BackColor is set to SystemColors.HighlightText. If the item's state is not Selected, the BackColor property is set to SystemColors.Window.
