I have a little visual problem. In IE8 a Hyperlink Column that is no AlternateItem and is not Hovered 
shows the Link Decoration (Underline) for the Hole Link text when only parts of the Text ist visible,
when hovered with Mouse the decoration gets fit to the columnwidth (see pictures)

Hi John,

This looks like a browser bug, but nevertheless,  I cannot reproduce it locally. Below is my test page. Can you modify it, so that the problem is exhibited?

(I also tried adding a GridImageColumn next to the hyperlink column, with no success)

<%@ Page Language="C#" %>
<%@ Import Namespace="System.Data" %>
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
 
<script runat="server">
 
    protected void RadGrid_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
    {
        DataTable dt = new DataTable();
        DataRow dr;
        int colsNum = 4;
        int rowsNum = 2;
        string colName = "Column";
 
        for (int j = 1; j <= colsNum; j++)
        {
            dt.Columns.Add(String.Format("{0}{1}", colName, j));
        }
 
        for (int i = 1; i <= rowsNum; i++)
        {
            dr = dt.NewRow();
 
            for (int k = 1; k <= colsNum; k++)
            {
                dr[String.Format("{0}{1}", colName, k)] = String.Format("{0}{1} Row{2}", colName, k, i);
            }
            dt.Rows.Add(dr);
        }
 
        (sender as RadGrid).DataSource = dt;
    }
 
    protected void Page_Load(object sender, EventArgs e)
    {
        if (IsPostBack)
        {
            Unit u = Unit.Parse("137.5px");
        }
    }
     
</script>

With you provided code i also does not have this effect. So i tried to fill your code with parts of mine and voila... the effect is visible.

So here is my modified code:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="Default" %>
<%@ Import Namespace="System.Data" %>
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
  
<script runat="server">
  
    protected void RadGrid_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
    {
        DataTable dt = new DataTable();
        DataRow dr;
        int colsNum = 17;
        int rowsNum = 7;
        string colName = "Column";
  
        for (int j = 1; j <= colsNum; j++)
        {
            dt.Columns.Add(String.Format("{0}{1}", colName, j));
        }
  
        for (int i = 1; i <= rowsNum; i++)
        {
            dr = dt.NewRow();
  
            for (int k = 1; k <= colsNum; k++)
            {
                if (k == 9)
                {
                    dr[String.Format("{0}{1}", colName, k)] = String.Format("{0}{1} Row{2} aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa", colName, k, i);
                }
                else
                {
                    dr[String.Format("{0}{1}", colName, k)] = String.Format("{0}{1} Row{2}", colName, k, i);
                }
            }
            dt.Rows.Add(dr);
        }
  
        (sender as RadGrid).DataSource = dt;
    }
  
    protected void Page_Load(object sender, EventArgs e)
    {
        if (IsPostBack)
        {
            Unit u = Unit.Parse("137.5px");
        }

DataTextFormatStringHi John,

Thanks. I stripped your demo to a point in which the problem was exhibited if the image column had no ImageUrl specified, but everything looked OK when an image was set.

In addition, the problem is not observed, if I add the following CSS rule to the page:

.RadGrid  a
{
     zoom:1;
}

(Note that the ellipsis is lost in this case).

This is definitely a browser bug. You can any workaround, which suits your requirements - e.g. use shorter hyperlink text, which does not overflow the column - by setting DataTextFormatString
