How to implement the strikethrough feature in the WinForms SyntaxEditor (EditControl)?

private void menuItem1_Click(object sender, System.EventArgs e)
{
   // Strike out the current line
   this.editControl1.StrikeThrough(this.editControl1.CurrentLine, Color.IndianRed);
}
private void menuItem2_Click(object sender, System.EventArgs e)
{
   // Strike out the selected text
   this.editControl1.StrikeThrough(this.editControl1.Selection.Top, this.editControl1.Selection.Bottom, Color.Navy);
}
private void menuItem3_Click(object sender, System.EventArgs e)
{
   int startOffsetValue = 100;
   int endOffsetValue = 240;
   // Starting offset converted to virtual point
   Point startVirtualPoint = this.editControl1.ConvertOffsetToVirtualPosition(startOffsetValue);
   // Ending offset converted to virtual point
   Point endVirtualPoint = this.editControl1.ConvertOffsetToVirtualPosition(endOffsetValue);
   // Converting the VirtualPoints to ParsePoints
   ParsePoint startParsePoint = new ParsePoint(startVirtualPoint.Y, startVirtualPoint.X, 0);
   ParsePoint endParsePoint = new ParsePoint(endVirtualPoint.Y, endVirtualPoint.X, 0);
   // Creating the associated CoordinatePoints that indicate the text range
   CoordinatePoint startCoordinatePoint = new CoordinatePoint((ILexemParser)this.editControl1.Parser,    startParsePoint, startVirtualPoint.Y, startVirtualPoint.X, true);
   CoordinatePoint endCoordinatePoint = new CoordinatePoint((ILexemParser)this.editControl1.Parser, endParsePoint, endVirtualPoint.Y, endVirtualPoint.X, true);
   // Strike out the text in the specified text range
   this.editControl1.StrikeThrough(startCoordinatePoint, endCoordinatePoint, Color.Brown);
}
