    I have the following Multicolumn Combobox on my page:
    <telerik:RadComboBox ID="ddlLineNum" runat="server" DataValueField="all_line_id"
        DataTextField="line_number" Width="250px" Skin="Windows7" HighlightTemplatedItems="True"
        DropDownWidth="290px" AutoPostBack="True">
            <table border="0" cellpadding="0" cellspacing="0">
                    <td style="width: 75px;">
                        <%#DataBinder.Eval(Container.DataItem, "line_number")%>
                    <td style="width: 200px; padding-left: 5px;">
                        <%#DataBinder.Eval(Container.DataItem, "line_description")%>

    The 1st column contains a telephone number.  I would like to format it so it actually looks like one.  I figured I could do it in the _ItemDataBound event, but I can't quite figure it out?

    If you're using the ItemTemplate, why not format it using the third parameter offered by the DataBinder.Eval method.

    I hope that helps.

    That would work in a perfect world, unfortunately that is not the world this app operates in.  See the content is dynamic.  The content is determined by other choices made on the form.  Sometimes the content is a traditional telephone number, sometimes it's not.  When it's not, I don't want to apply formatting. 

    Thanks anyway.  At least now I know that there even is a 3rd parameter used for formatting.

    Hi SSirica,

    In this case, you can substitute this:
    <%#DataBinder.Eval(Container.DataItem, "line_number")%>

    with an ASP.NET Literal and set its Text property in the ItemDataBound event handler to the current value. You can find the Literal control in the Item, e.g.
    e.Item.FindControl("Literal1") as Literal;

    You can read more about the ItemDataBound event and its usage here.
