How to show raw XML string in Telerik:RadGrid columns without rendering

I have a telerik:GridBoundColumn in my telerik:RadGrid as a string type with some XML codes.

How can I show that column (raw XML) in that RadGrid without rendering?

My problems: my grid direction is right to left for some reason...
so at first I should change the xml direction like below : 

<telerik:GridBoundColumn DataField="Settings" FilterControlAltText="Filter Settings column" DataFormatString="<span style='direction:ltr;'>{0}</span>"
    HeaderText="Settings" SortExpression="Settings" 
    UniqueName="Settings" FilterImageToolTip="Filter" HtmlEncode="false">
    <HeaderStyle HorizontalAlign="Right" VerticalAlign="Middle" />
    <ItemStyle HorizontalAlign="Left" VerticalAlign="Middle" />
</telerik:GridBoundColumn>

Currently we have an XML string with ltr direction in grid. After that I change to HtmlEncode="TRUE", but by doing so I lose the ltr direction. so I set HtmlEncode back to false.

I figured out I can use <xmp> or <pre> elements. But with <xmp> I have some replacement of < and > in grid and also it has been deprecated... and with <pre> I should change all < to &lt; and > to &gt; in my database, which is unfeasible.

Add handler for onItemDataBound for your Grid

<telerik:RadGrid ID="RadGrid1" runat="server" AllowFilteringByColumn="True"
            AllowSorting="True" PageSize="50" ShowFooter="True" AllowPaging="True" 
            AutoGenerateColumns="False" GridLines="None" ShowStatusBar="true" 
                onitemdatabound="RadGrid1_ItemDataBound">

And codebehind:

 protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
 {
            if (e.Item is GridDataItem)
            {
                GridDataItem item = e.Item as GridDataItem;
                item["XmlColumn1"].Text = Server.HtmlEncode(item["XmlColumn1"].Text);
                item["XmlColumn2"].Text = Server.HtmlEncode(item["XmlColumn2"].Text);
            }

  }

Should do the trick.
