I try to draw the dashed line(------------) inside the cell right below to the text which is being showed in the cell. Something similar to Url link which comes very below to the text but dashed line rather fixed line using the interface UIElementDrawFilter. I got following drawback.

1. My last cell is only being painted.

2. Dashed line comes above the bottom line of the cell. I need it into very below to the text.

Code:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using Infragistics.Shared;
using Infragistics.Win;
using Infragistics.Win.UltraWinGrid.Design;
using Infragistics.Win.UltraWinGrid;
using System.Drawing.Drawing2D;

namespace WindowsApplication9
{
    public partial class Form1 : Form, Infragistics.Win.IUIElementDrawFilter
    {
        private string drawlineafter = string.Empty;
        private DashStyle dashstyle = DashStyle.Dash;

        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {

            DataTable dt = new DataTable();

            DataRow myNewRow, myNewRow1, myNewRow2;
            dt.Columns.Add(new DataColumn("customerId"));
            dt.Columns.Add(new DataColumn("username"));

            myNewRow = dt.NewRow();
            myNewRow["customerId"] = 1;
            myNewRow["username"] = "johndoe";
            dt.Rows.Add(myNewRow);
           
            myNewRow1 = dt.NewRow();
            myNewRow1["customerId"] = 2;
            myNewRow1["username"] = "Uthay";
            dt.Rows.Add(myNewRow1);

            myNewRow2 = dt.NewRow();
            myNewRow2["customerId"] = 3;
            myNewRow2["username"] = "Steve";
            dt.Rows.Add(myNewRow2);

            ultraGrid1.DataSource = dt;

            this.ultraGrid1.DrawFilter = this;




        }

        #region IUIElementDrawFilter Members
        public bool DrawElement(Infragistics.Win.DrawPhase drawPhase, ref Infragistics.Win.UIElementDrawParams drawParams)
        {

            TextUIElement textval = (TextUIElement)drawParams.Element;
 
            if (string.IsNullOrEmpty(textval.Text))
                return false;
            if ((textval == null) || (textval.Parent == null))
                return false;

            Rectangle rect = drawParams.Element.Rect;
            Point pt1 = Point.Empty;
            Point pt2 = Point.Empty;
            pt1.Y = rect.Top + (rect.Height);
            pt1.X = rect.Left + (rect.Width) - 1;
            pt2.X = rect.Right - (rect.Width) + 1;
            pt2.Y = pt1.Y;

            using (Pen pen = new Pen(drawParams.TextBrush))
            {
                Point pt = Point.Empty;
                pt.X = rect.X;
                pt.Y = rect.Y;
                pen.DashStyle = this.dashstyle;
                drawParams.Graphics.DrawLine(pen, pt1, pt2);
                drawParams.Graphics.DrawString(textval.Text.ToString(), drawParams.Font, drawParams.TextBrush, pt);
            }
 
            return true;
        }


        public Infragistics.Win.DrawPhase GetPhasesToFilter(ref Infragistics.Win.UIElementDrawParams drawParams)
        {
            return drawParams.Element is Infragistics.Win.TextUIElement ? Infragistics.Win.DrawPhase.BeforeDrawElement : Infragistics.Win.DrawPhase.None;
        }

        #endregion

        private void ultraGrid1_InitializeLayout(object sender, InitializeLayoutEventArgs e)
        {
           

        }

    }
}

How to achieve things? Some one help me on this please.
