Using Cascading Dropdown

[LucBite]

I'm using a cascading dropdownlist using three tables. the code below works fine if my primary keys are numeric(integer) but my business rules want the primary keys to be alphernumeric(string). [WebMethod] public CascadingDropDownNameValue[] GetColors(string knownCategoryValues, string category) { StringDictionary kv = CascadingDropDown.ParseKnownCategoryValuesString(knownCategoryValues); int colorId; if (!kv.ContainsKey("Model") || !Int32.TryParse(kv["Model"],out colorId)) { return null; } dsModelColorsTableAdapters.ModelColorsTableAdapter adapter = new dsModelColorsTableAdapters.ModelColorsTableAdapter(); dsModelColors.ModelColorsDataTable colors = adapter.GetColorsByModelId(colorId); List<CascadingDropDownNameValue> values = new List<CascadingDropDownNameValue>(); foreach (DataRow dr in colors) { values.Add(new CascadingDropDownNameValue((string)dr["ColorName"], dr["ColorID"].ToString())); } return values.ToArray(); } How do I use my string primary key using the above code? Please help an ajax technology adict.
