    Let me know whether the following example helps you. That's how i would implement it, if i understand your scenario correctly.

    <!DOCTYPE html>
<html>
<head runat="server">
</head>
<body>
    <ext:ResourceManager runat="server" />
    <ext:ComboBox FieldLabel="Field 1" ID="Field1" runat="server">
        <Items>
            <ext:ListItem Text="Ext.NET" Value="1" />
            <ext:ListItem Text="Sencha" Value="2" />
            <ext:ListItem Text="Microsoft" Value="3" />
        </Items>
        <Listeners>
            <Select Handler="#{_str}.loadPage(1)" />
        </Listeners>
    </ext:ComboBox>
    <ext:GridPanel Title="Ext.NET" Border="true" Width="500" Height="400" runat="server">
        <Store>
            <ext:Store ID="_str" AutoLoad="true" runat="server">
                <Proxy>
                    <ext:AjaxProxy Url="~/Example/LoadFakeRecords/">
                        <Reader>
                            <ext:JsonReader RootProperty="data" />
                        </Reader>
                    </ext:AjaxProxy>
                </Proxy>
                <Model>
                    <ext:Model IDProperty="ID" runat="server">
                        <Fields>
                            <ext:ModelField Name="ID" Type="String" />
                            <ext:ModelField Name="Name" Type="String" />
                        </Fields>
                    </ext:Model>
                </Model>
                <Parameters>
                    <ext:StoreParameter Name="field1" Value="#{Field1}.getValue()" Mode="Raw" />
                </Parameters>
            </ext:Store>
        </Store>
        <ColumnModel runat="server">
            <Columns>
                <ext:Column Text="ID" DataIndex="ID" runat="server" />
                <ext:Column Text="Name" Flex="1" DataIndex="Name" runat="server" />
            </Columns>
        </ColumnModel>
    </ext:GridPanel>
</body>
</html>
    namespace SandBox.Controllers
{
    public class ExampleController : System.Web.Mvc.Controller
    {
        public ActionResult Index()
        {
            return View();
        }

        public StoreResult LoadFakeRecords(Nullable<int> field1)
        {
            List<Entity> lst = new List<Entity>();

            for (int index = 1; index < 16; index++)
            {
                lst.Add(new Entity
                {
                    ID = index,
                    Name = string.Format("Name - {0:00} - {1}", index, DateTime.Now.ToLongTimeString())
                });
            }

            return new StoreResult(lst, lst.Count());
        }
    }

    [Serializable]
    public class Entity
    {
        public int ID { get; set; }

        public string Name { get; set; }
    }
}
