[Solved] Passing an array when loading/sorting with ajax binding

[Dario]

Hi.
When my grid loads or I do something with it (sorting the columns, grouping etc.) I want to pass an array of IDs of Books to the controller. And than the controller should use Linq to SQL to fetch the Books from the database and filter out the Books with IDs that I have passed.

I have tried with: .DataBinding(dataBinding => dataBinding.Ajax().Select("_AjaxBinding", "Controller", new { IDBooks }))
and: using ClientEvent: .OnDataBinding("onDataBinding") and in onDataBinding function pass the array on countless ways but no resault. Eg. 

var $IDBooks = $('input[name="IDBooks"]');
var grid = $("#BooksForBorrowing").data("tGrid");
grid.rebind({ IDBooks: $IDBooks });

or:

var $IDBooks= $('input[name="IDBooks"]');
// pass additional values by setting the "data" field of the event argument
e.data = {
    IDBooks: $IDBooks
};

I was reading all sorts of posts and blogs but nothing helps me.
Is there any way to do this?

Hello Dario,

Basically, you should pass the parameters with names in the format "ActionParameterName[index]" in order to send the array to the action method. For example:

function onDataBinding(e) {
    var idBooks = {};
    $('input[name="IDBooks"]').each(function (index) {
        idBooks["IDBooks[" + index + "]"] = $(this).val();
    });


    e.data = idBooks;
}

To send the array through the request route values, you can use a RouteValueDictionary with parameters in the same format.


Kind regards,

Thank you for the reply.
I solved it in a bid different but ugly way.
I used Request.Form["IDBooks"].ToString() in controller with which I got values of hidden fields (each hidden field contained one ID of a book). Than I parsed those IDs to int's and from there I could use them.

I will also probably try out your solution.
