ToolStripRenderer.OnRenderToolStripBorder(ToolStripRenderEventArgs) Method

Definition

Raises the RenderToolStripBorder event.

protected virtual void OnRenderToolStripBorder (System.Windows.Forms.ToolStripRenderEventArgs e);

Parameters

e
ToolStripRenderEventArgs

A ToolStripRenderEventArgs that contains the event data.

Examples

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);
}

Remarks

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