Raises the RenderToolStripBorder event.
protected:
virtual void OnRenderToolStripBorder(System::Windows::Forms::ToolStripRenderEventArgs ^ e);
protected virtual void OnRenderToolStripBorder (System.Windows.Forms.ToolStripRenderEventArgs e);
abstract member OnRenderToolStripBorder : System.Windows.Forms.ToolStripRenderEventArgs -> unit
override this.OnRenderToolStripBorder : System.Windows.Forms.ToolStripRenderEventArgs -> unit
Protected Overridable Sub OnRenderToolStripBorder (e As ToolStripRenderEventArgs)
A ToolStripRenderEventArgs that contains the event data.
The following code example demonstrates how to override the OnRenderToolStripBorder method to draw a custom border around a ToolStrip control. This code example is part of a larger example provided for the ToolStripRenderer class.
// This method draws a border around the GridStrip control.
protected override void OnRenderToolStripBorder(
ToolStripRenderEventArgs e)
{
base.OnRenderToolStripBorder(e);
ControlPaint.DrawFocusRectangle(
e.Graphics,
e.AffectedBounds,
SystemColors.ControlDarkDark,
SystemColors.ControlDarkDark);
}
' This method draws a border around the GridStrip control.
Protected Overrides Sub OnRenderToolStripBorder(e As ToolStripRenderEventArgs)
MyBase.OnRenderToolStripBorder(e)
ControlPaint.DrawFocusRectangle(e.Graphics, e.AffectedBounds, SystemColors.ControlDarkDark, SystemColors.ControlDarkDark)
End Sub
Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
The OnRenderToolStripBorder method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
When overriding OnRenderToolStripBorder(ToolStripRenderEventArgs) in a derived class, be sure to call the base class's OnRenderToolStripBorder(ToolStripRenderEventArgs) method so that registered delegates receive the event.
