Question

The Master grid is Customers and the Detail grid is a Customers Orders. Using the EditorTemplate, I have the Model working just fine for updates but when it comes to inserting new records I’m at a loss.

The CustomerId is not being passed, in any way that I can see, to the UserControl. So new Orders are being created with a CustomerId of 0.

The Orders table has a unique key on CustomerId and Order # and OrdersId is primary. I need to create a new Customer Order record entering the Order # but the Customer # needs to be provided to the form.

I am obviously missing something and certainly don’t see any help on the Telerik site when it comes to their grid and MVC.

Any help would be greatly appreciated!

Answer 1

The record id is always returned as “id” and must be coded that way.

[GridAction]
public ActionResult _SaveMasterTable(int id) {
    using (DataContext dc = new DataContext()) {
        MasterTable model = dc.MasterTables.SingleOrDefault(
            e => (e.MasterId == id)
        );e

In the case above the Master record would be updated. For child records, the record id returned is the masters… allowing you to insert the new record with the master id.
