    [CLOSED] How to create Panel Loader programmatically

    Hi,
    I implemented programmatically a Panel with a Loader this is the code below : 
     Panel subPanel = new Panel();
            subPanel.Loader.ID = "_" + tabTag + "Loder";
    I had a crash on the second instruction, this is the exception : "Object reference not set to an instance of an object"

    Hi,

    You should apply a ComponentLoader instance.

    Example
    <%@ Page Language="C#" %>

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

<script runat="server">
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!X.IsAjaxRequest)
        {
            Ext.Net.Panel p = new Ext.Net.Panel();
            p.Width = 400;
            p.Height = 400;

            ComponentLoader loader = new ComponentLoader();
            loader.Mode = LoadMode.Frame;
            loader.Url = "http://ext.net";

            p.Loader = loader;

            this.Controls.Add(p);
        }
    }
</script>

<!DOCTYPE html>

<html>
<head runat="server">
    <title>Ext.NET v2 Example</title>
</head>
<body>
    <ext:ResourceManager runat="server" />
</body>
</html>
