JavaScript

So im trying to creae a dynamic data project using asp.net.
 
my project has 2 tables, FruitTable and SellerTable.
 
I had it set so the primary key in 'fruit table': name. was the foreign key in 'seller table'
 
I added a new class which contains the code to link to the new fieldTemplate I added(DropDown)
 
 <pre lang="c#">[MetadataType(typeof(UsingDropDownMetadata))]
    public partial class UsingDropDown
    {
    }
 
    public class UsingDropDownMetadata
    {
        //DropDown is name of field templates
        [UIHint("DropDown")]
        //use in field date in tracing table
        public object DropDownFromTextBox { get; set; }
    }

protected void OnSelectedIndexChangedMethod(object sender, EventArgs e)
{
 
//text here

}
