Does anyone have/know of any examples for something similar to this:
Telerik Sample For Multiple Resources
Except, with multi-valued resources? I'm new to entity data sources, and I'm just inheriting a project that has an existing model that works. But the owner is asking for a new resource type to be added that has a one-to-many relationship for "department(s)". If this was a standard 3-tier system, I would have no trouble getting this completed.
I've got the database updated to the model I THINK by creating a link table Called "EventDepartments" (Model Layout is attached). and I have the UI populating with the checkbox list. But...
- There is an Integrity error on insert/update: "The type of the key field 'ID' is expected to be 'System.Int32', but the value provided is actually of type 'System.Object[]'."
- I have no idea where to go from here, as I don't know where to look for the issue since the appointment form is auto-generated/handled.
