[CLOSED] Infinite Scrolling with MVC

[RCN]

Hi folks, i´m trying to implement a Grid with infinite scrolling using mvc. I tried to do it using https://examples2.ext.net/#/GridPane.../Forum_topics/ as example but i was not able to accomplish this task

The function LoadRecords is called but the records are loaded in the grid.

Could someone give me directions to overcome this problem?

Thanks in advance

View

<ext:Panel ID="Panel1" runat="server" PreventHeader="true" Border="false">
    <Loader ID="Loader1" runat="server" Mode="Component" AutoLoad="true" Url="/Example/Internal/">
        <Params>
            <ext:Parameter Name="containerId" Value="Panel1" Mode="Value" />
        </Params>
        <LoadMask ShowMask="true" />
    </Loader>
</ext:Panel>

Interface Generator

public ContentResult Internal(string containerId)
{
    //Grid
    GridPanel grd = new GridPanel { ID = "_grd", Title = "example", Height = 200 };
    grd.Listeners.AfterRender.Handler = "alert('Saldanha'); var me = this; me.store.prefetch({start: 0, limit: 99, callback: function() { me.store.guaranteeRange(0, 49); }});";
    grd.Listeners.AfterRender.Delay = 100;
                  
    //Proxy
    JsonPProxy proxy = new JsonPProxy();
    proxy.Reader.Add(new JsonReader { Root = "data", TotalProperty = "total" });
    proxy.Url = "/Example/Test/";

    //Store
    Store str = new Store { ID = "_str", AutoLoad = false, Buffered = true };
    str.Proxy.Add(proxy);
    grd.Store.Add(str);

    //Model
    Model mdl = new Model { IDProperty = "ID" };
    addColumn("ID", grd, mdl);
    addColumn("Name", grd, mdl);
    str.Model.Add(mdl);

    //Result
    ContentResult r = new ContentResult();

    r.Content = ComponentLoader.ToJson(grd);

    return r;
}

private void addColumn(string id, GridPanel grd, Model mdl)
{
    ModelField mdf = new ModelField(id);

    Column cln = new Column { ID = id, DataIndex = id, Sortable = true, Text = string.Format("_cln{0}", id) };

    if (id == "ID")
    {
        mdl.IDProperty = id;
    }

    mdl.Fields.Add(mdf);

    grd.ColumnModel.Columns.Add(cln);
}

Data Load

public StoreResult Test(int start, int limit)
{
    List<Person> lst = new List<Person>();

    for (int index = 0; index < limit; index++)
    {
        lst.Add(new Person { ID = index, Name = "Ext" + (start + index) });
    }
    return new StoreResult(lst, limit);
}

Entity

public class Person
{
    public int ID { get; set; }

    public string Name { get; set; }
}
