[Solved] Linking to a parameterised Ajax bound form

[Stuart]

I have a number of forms populated using Ajax binding, so for each of these forms I have two action methods, one of which has the GridAction attribute, all this is working fine;

public virtual ViewResult Orders() {}

[GridAction]
public virtual ViewResult OrdersAjax() {}

I have another form (call it the source form), from this form I want to link to the above target forms using a URL and pass in some filter to the Ajax bound forms, filtering for example on customer Id and order Id. I've added a bunch of buttons on the source form on each row, I want to set some link on the URL of these buttons so that they each call one of the target forms passing in data specific to the data row holding the buttons. The target Ajax bound form when displayed will be filtered using the argumens passed from the source.
I understand that I can add parameters to the Ajax method and then enter those parameters in the Select statement of the the calling form e.g. I'd adapt the above to

[GridAction]
public virtual ViewResult OrdersAjax(int orderId, int customerId) {}

and then in the source grid the binding statement would look like;

.DataBinding(dataBinding => dataBinding.Ajax().Select<TheController>(controller => controller.OrdersAjax(123, 567)))

However this only provides for one set of arguments for all rows in the source of the link.

How can I configure my source grid such that I can send row specific arguments to another ajax bound grid and filter on those arguments?
Ultimately I need to have a menu that links to a number of forms filtering based on the source form.
