{
// Create a new ContextMenuStrip control.
ContextMenuStrip checkImageContextMenuStrip = new ContextMenuStrip();
// Create a ToolStripMenuItem with a
// check margin and an image margin.
ToolStripMenuItem yesCheckYesImage =
new ToolStripMenuItem("Check, Image");
yesCheckYesImage.Checked = true;
yesCheckYesImage.Image = CreateSampleBitmap();
// Create a ToolStripMenuItem with no
// check margin and with an image margin.
ToolStripMenuItem noCheckYesImage =
new ToolStripMenuItem("No Check, Image");
noCheckYesImage.Checked = false;
noCheckYesImage.Image = CreateSampleBitmap();
// Create a ToolStripMenuItem with a
// check margin and without an image margin.
ToolStripMenuItem yesCheckNoImage =
new ToolStripMenuItem("Check, No Image");
yesCheckNoImage.Checked = true;
// Create a ToolStripMenuItem with no
// check margin and no image margin.
ToolStripMenuItem noCheckNoImage =
new ToolStripMenuItem("No Check, No Image");
noCheckNoImage.Checked = false;
// Add the ToolStripMenuItems to the ContextMenuStrip control.

checkImageContextMenuStrip.Items.Add(yesCheckNoImage);
checkImageContextMenuStrip.Items.Add(noCheckNoImage);
return checkImageContextMenuStrip;
