Examples

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the RenderLabelBackground event. This report helps you to 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 a type that inherits from ToolStripRenderer, such as a ToolStripSystemRenderer or ToolStripProfessionalRenderer. Then name the instance ToolStripRenderer1 and ensure that the event handler is associated with the RenderLabelBackground event.

private void ToolStripRenderer1_RenderLabelBackground(Object sender, ToolStripItemRenderEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "Graphics", e.Graphics );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Item", e.Item );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ToolStrip", e.ToolStrip );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "RenderLabelBackground Event" );
}

Private Sub ToolStripRenderer1_RenderLabelBackground(sender as Object, e as ToolStripItemRenderEventArgs) _ 
     Handles ToolStripRenderer1.RenderLabelBackground

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "Graphics", e.Graphics)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Item", e.Item)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "ToolStrip", e.ToolStrip)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"RenderLabelBackground Event")

End Sub
