ToolStripRenderer.RenderButtonBackground Event

Definition

Occurs when the background for a ToolStripButton is rendered.

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

private void ToolStripRenderer1_RenderButtonBackground(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(), "RenderButtonBackground Event" );
}
Private Sub ToolStripRenderer1_RenderButtonBackground(sender as Object, e as ToolStripItemRenderEventArgs) _ 
     Handles ToolStripRenderer1.RenderButtonBackground

    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(),"RenderButtonBackground Event")

End Sub
