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.
<asp:DropDownList ID="DDLCat" runat="server" Width="199px" />
SelectedValue='<%# Bind("CERTCATID") %>'
