ToolStripRenderer.RenderItemBackground Event

Definition

Occurs when the background for a ToolStripItem is rendered.

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

private void ToolStripRenderer1_RenderItemBackground(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(), "RenderItemBackground Event" );
}
Private Sub ToolStripRenderer1_RenderItemBackground(sender as Object, e as ToolStripItemRenderEventArgs) _ 
     Handles ToolStripRenderer1.RenderItemBackground

    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(),"RenderItemBackground Event")

End Sub
