    [CLOSED] MVC - Loading UserControl's with PartialViewResult

    Hi @all,

    I load on clientside with jscript UserControls in Asp - Repeater.

    Here some code snippets to understand the situation.

    .js
    var p_new_item = new Ext.Panel({
        id: name_control,
        layout: 'fit',
        border: false
    });

    var p_loader = new Ext.Panel({
        id: name_loader,
        border: false,
        hidden: true,
        loader: {
            url: url,
            disableCaching: true,
            scripts: true,
            params: {
                containerId: p_new_item.id,
                contSID: contSID
            }
        }
    });
    
    p_list.add(p_loader);
    p_list.add(p_new_item);
    .Controller.cs
    public ActionResult uc_ContText(string containerId, string contSID)
 {           

            this.ViewData["contSID"] = contSID;

            var pr = new Ext.Net.MVC.PartialViewResult(containerId);
            pr.ViewData = ViewData;
            pr.RenderMode = Ext.Net.RenderMode.AddTo;
            pr.SingleControl = true;
            pr.IDMode = Ext.Net.IDMode.Explicit;
           
            return pr;
        }
    That works with a UserControl (.ascx) which was developed with Ext.Net but not with UserControl with Asp-Code.
    If I build a ext:Panel around the asp-div, it works too!

    .ascx
    <ext:Panel runat="server">
    <Content>
         <div>
                //My UserContol.....
         </div>
    </Content>
</ext:Panel>
    How I can Asp-UserControls load without Ext.Net -Code ??
    Thanks!

    Hi @ontiv,

    I think you cannot use these options:
    pr.RenderMode = Ext.Net.RenderMode.AddTo;
pr.SingleControl = true;
    if a partial view contains native ASP.NET controls on the top level.

    It would be simplest to wrap an ASP.NET control in an additional Ext.NET container.
    <ext:Container runat="server">
    <Content>
        <asp:Label runat="server" Text="Hello!" />
    </Content>
</ext:Container>
    Also I would recommend you to use Mode="Component" for a Loader.

    Example

    Page
    <%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<!DOCTYPE html>
<html>
<head runat="server">
    <title>Ext.Net.MVC v2 Example</title>
</head>
<body>
    <ext:ResourceManager runat="server" />

    <ext:Panel ID="Panel1" runat="server" Width="200" Height="200">
        <Loader runat="server" Mode="Component" Url="/Aspx/Partial" />
    </ext:Panel>
</body>
</html>
    Partial View
    <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %>

<ext:Container runat="server">
    <Content>
        <asp:Label runat="server" Text="Hello!" />
    </Content>
</ext:Container>

    Controller Action
    public ActionResult Partial()
{
    return Json(ComponentLoader.ToConfig("~/Views/Aspx/Partial.ascx"), JsonRequestBehavior.AllowGet);
}
