En el ejemplo de código siguiente se muestra cómo inicializar controles individuales ToolStripItem . Este ejemplo de código es parte de un ejemplo mayor proporcionado para la clase ToolStripRenderer.

// This method initializes an individual ToolStripButton
// control. It copies a subimage from the GridStripRenderer's
// main image, according to the position and size of 
// the ToolStripButton.
protected override void InitializeItem(ToolStripItem item)
{
    base.InitializeItem(item);

    GridStrip gs = item.Owner as GridStrip;

    // The empty cell does not receive a subimage.
    if ((item is ToolStripButton) &&
        (item != gs.EmptyCell))
    {
        // Copy the subimage from the appropriate 
        // part of the main image.
        Bitmap subImage = bmp.Clone(
            item.Bounds,
            PixelFormat.Undefined);

        // Assign the subimage to the ToolStripButton
        // control's Image property.
        item.Image = subImage;
    }
