I'm new to Ajax, but I think I know how to reasonably use MVC + model binding.
What I'm trying to do is to create an Add button (or Ajax.ActionLink) to add a new row in my grid for data entry. Example: Think of a typical Order entry system with Order (header) and Product (items). My OrderViewModel contains an "Order" object, and the Order object contains a collection List.
The way I plan to do this is that my View render the grid in a PartialView, and the PartialView is a simple for-loop to create the table tags from the List. I will use the default model binder (for collections).
Anyone have suggestions on how to do this?
I've already figured out how to do this using jQuery, but I want (i think I want) to try and use Ajax so that I can add my custom business logic (e.g. like setting defaults, translations, etc.)as opposed to do this client-side.
In other words, I want to do do something similar to what the Telerik grid does with its Ajax Editing with the Add/Remove link/buttons.
Tips and sample code would be greatly appreciated.
One of my challenges, and not sure if I'm going down the wrong way, is that I don't know how to pass back the model back to the Controller Action from the Ajax submit. When I look at Telerik's code, it looks like they store the persisted items in HttpContext.Session, and this is exactly the reason why I don't want to use their grid.
Thanks.
They might choose the session repository storage for demonstration purposes. If you transform the logic from their SessionProductRepository class for your model and implement identical Update/Insert/Delete methods for it, you'll probably get what you want.
