Error while running MVC Application including JQuery Grid Plugins
<p>I am getting the following error while running my MVC Application that consists of the jquery grid plugins.</p>

<pre><code>The parameters dictionary contains a null entry for parameter 'page' of non-nullable type 'System.Int32' for method 'System.Web.Mvc.ActionResult GetCategory(System.String, System.String, Int32, Int32)' in 'ecom.Controllers.AdminController'. To make a parameter optional its type should be either a reference type or a Nullable type.
Parameter name: parameters
</code></pre>

<hr>

<pre><code>public ActionResult GetCategory(string sidx, string sord, int page, int rows)
{
    var jsonData = _Category.GetAll().ToJsonForjqGrid("category_id", new[] { "category_id", "category_name" });
    return Json(jsonData);
}
</code></pre>

<p>In the <code>getCategory</code> view I am using it in this way:</p>

<pre><code>&lt;script language="javascript" type="text/javascript"&gt;

        loadProducts();

&lt;/script&gt;
</code></pre>
