ToolStripRenderer.OnRenderToolStripBorder Method

Raises the RenderToolStripBorder event.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

protected virtual void OnRenderToolStripBorder(
	ToolStripRenderEventArgs e
)

Parameters

e
Type: System.Windows.Forms.ToolStripRenderEventArgs

A ToolStripRenderEventArgs that contains the event data.

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.

Notes to Inheritors

When overriding OnRenderToolStripBorder in a derived class, be sure to call the base class's OnRenderToolStripBorder method so that registered delegates receive the event.

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);
}
