public:
event System::Windows::Forms::ToolStripContentPanelRenderEventHandler ^ RenderToolStripContentPanelBackground;
public event System.Windows.Forms.ToolStripContentPanelRenderEventHandler RenderToolStripContentPanelBackground;
member this.RenderToolStripContentPanelBackground : System.Windows.Forms.ToolStripContentPanelRenderEventHandler
Public Custom Event RenderToolStripContentPanelBackground As ToolStripContentPanelRenderEventHandler
The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the RenderToolStripContentPanelBackground 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 RenderToolStripContentPanelBackground event.
private void ToolStripRenderer1_RenderToolStripContentPanelBackground(Object sender, ToolStripContentPanelRenderEventArgs e) {
System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "Graphics", e.Graphics );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Handled", e.Handled );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ToolStripContentPanel", e.ToolStripContentPanel );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "RenderToolStripContentPanelBackground Event" );
}
Private Sub ToolStripRenderer1_RenderToolStripContentPanelBackground(sender as Object, e as ToolStripContentPanelRenderEventArgs) _
Handles ToolStripRenderer1.RenderToolStripContentPanelBackground
Dim messageBoxVB as New System.Text.StringBuilder()
messageBoxVB.AppendFormat("{0} = {1}", "Graphics", e.Graphics)
messageBoxVB.AppendLine()
messageBoxVB.AppendFormat("{0} = {1}", "Handled", e.Handled)
messageBoxVB.AppendLine()
messageBoxVB.AppendFormat("{0} = {1}", "ToolStripContentPanel", e.ToolStripContentPanel)
messageBoxVB.AppendLine()
MessageBox.Show(messageBoxVB.ToString(),"RenderToolStripContentPanelBackground Event")
End Sub
