Definition

Occurs when the background for an overflow button is rendered.

public:
 event System::Windows::Forms::ToolStripItemRenderEventHandler ^ RenderOverflowButtonBackground;
public event System.Windows.Forms.ToolStripItemRenderEventHandler RenderOverflowButtonBackground;
member this.RenderOverflowButtonBackground : System.Windows.Forms.ToolStripItemRenderEventHandler 
Public Custom Event RenderOverflowButtonBackground As ToolStripItemRenderEventHandler 

Event Type

Examples

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the RenderOverflowButtonBackground 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 RenderOverflowButtonBackground event.

private void ToolStripRenderer1_RenderOverflowButtonBackground(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(), "RenderOverflowButtonBackground Event" );
}
Private Sub ToolStripRenderer1_RenderOverflowButtonBackground(sender as Object, e as ToolStripItemRenderEventArgs) _ 
     Handles ToolStripRenderer1.RenderOverflowButtonBackground

    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(),"RenderOverflowButtonBackground Event")

End Sub
