AJAX cascadingDropDown SelectedValue bind Issue

I have a CascadingDropDown  on my page and it works fine but when I Bind it to my SqlDataSource and try to update the database it throws an error. Aftersome research into the problem I found that the CascadingDropDown  Selectedvalue was returning DATAID:::DATAVALUE. With DATAID being the ID and DAVALUE being what shows in the DDL. So how do I get just the ID to Bind and not the rest. I have included the DDL and CDD just in case I messed up somewhere.

Thank You
<asp:DropDownList ID="DDLCat" runat="server" Width="199px" />
<cc1:CascadingDropDown ID="cddCertCat"  
runat="server"
TargetControlID="DDLCat" 
Category="Cat"
ServicePath="CertCatService.asmx"
ServiceMethod="GetCertCat"
SelectedValue='<%# Bind("CERTCATID") %>'
 /> 
[WebMethod]
    public CascadingDropDownNameValue[] GetCertCat(string knownCategoryValues, string category)
    {
 
        dsCertCatTableAdapters.TBLCERTCATTableAdapter catAdapter = new dsCertCatTableAdapters.TBLCERTCATTableAdapter();
        dsCertCat.TBLCERTCATDataTable cat = catAdapter.GetCertCat();
        List<CascadingDropDownNameValue> values = new List<CascadingDropDownNameValue>();
        foreach (DataRow dr in cat)
        {
            string CatDesc = (string)dr["CERTCATDESC"];
            int CATID = (int)dr["CERTCATID"];
            values.Add(new CascadingDropDownNameValue(CatDesc, CATID.ToString()));
        }
        return values.ToArray();
    }

I found a simple solution today. Apparently when trying to bind a cascadingdropdownbox  to a sql data source you have to bind the dropdownbox and eval the CDD as follows. Not sure why it works but it does and that is all I care about. :)

<asp:DropDownList ID="DDLCat" runat="server" Width="199px"  DataSourceID="SqlDataSource2" DataTextField="CERTCATDESC" DataValueField="CERTCATID" SelectedValue='<%# Bind("CERTCATID") %>' />

<cc1:CascadingDropDown ID="cddCertCat"  runat="server"TargetControlID="DDLCat" Category="Cat" PromptText="Please select a Category"ServicePath="CertCatService.asmx"ServiceMethod="GetCertCat"SelectedValue='<%# Eval("CERTCATID") %>'  
/>
