Question

I have a large data table that contains a checkbox for each row. I need to either pass all items that are selected as either a comma delimited list, or better yet a strongly typed IList to the controller. What is the best way to accomplish this? I know I can pass a string with no issue, but how do I get which checkboxes are selected?

Here’s what the static code looks like:

@using (@Html.BeginForm("RemoveItems", "ResultList", new { IDList = "1,2,3,4" }, FormMethod.Post))
{
    <input type="submit" value="Remove Items" name="RemoveItems" />
}

You can do it like this using jQuery.

    $.ajax({
        url: "/MyAction/Array",
        data: JSON.stringify({ model: input }),
        type: "POST",
        contentType: "application/json"
    });

Here “input” is your array, “model” – name of action parameter.
Make sure you’ve specified contentType as application/json.
