1. On a blank page I put a RadScriptManager, a RadAjaxManager, and a RadListBox, leaving everything set to the default skin. 
2. I add ten items to the list box via the Build RadListBox smart tag, all with the default text
3. Set AutoPostBack to true
4. Hook into the SelectedIndexChanged event, but do not add any code to the handler.
5. Configure the ajax manager so that the list box updates itself.

Hi.

I'm using GridDropDownColumn to display and edit values in grid:

As you can see, the <li> elements are all jammed together with no carriage returns, spaces, tabs, nothing, which is not standard.  At a minimum, you'd write an unordered list like this:

<ul>
<li>item 1</li>
<li>item 2</li>
</ul>

If I view source of my page, copy all the HTML and put it in a new static HTML page with carriage returns between the <li> elements as I indicated in the example above, the page displays correctly in both IE7 and IE8. So I ultimately need the HTML output of the TagCloud to look like this:

protected void itemUp_Click(object sender, ImageClickEventArgs e)
        {
            ImageButton imgB = (ImageButton)sender;
            GridDataItem dataItem = (GridDataItem)imgB.NamingContainer;
           
           
            string IsActive = dataItem["IsActive"].Text.ToString();
            if (IsActive == "1")
            {
                Int32 mapID = Int32.Parse(dataItem["Mapid"].Text.ToString());
                Int32 fTypeID = Int32.Parse(dataItem["FileTypeID"].Text.ToString());
                string Delimiter = dataItem["Delimiter"].Text.ToString();

                if (fTypeID == 1)
                    Response.Redirect("~/mapping/mapping.aspx?id=" + mapID.ToString());
                else
                    Response.Redirect("~/mapping/mappingDelimiter.aspx?id=" + mapID.ToString() + "&Del=" + Delimiter.ToString() + "&Ftype=" + fTypeID.ToString());
            }
            else
            {
                String s = "alert('This item must be set to Active before any processing is done with it!');";
                ScriptManager.RegisterClientScriptBlock(this.Page, this.GetType(), "alert", s, true);
            }

Below, is my markup. Once again, notice the boldfaced fields:
