    Probably just need to convert the Enum to a List, then bind to the DataSource of the Store.

    I believe there is a .ToList() option if you include the LINQ assemblies.

    Hope this helps.

    Hi,

    Please see the following sample
    <%@ Page Language="C#" %>
<%@ Register assembly="Ext.Net" namespace="Ext.Net" tagprefix="ext" %>
<%@ Import Namespace="System.Linq" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
    <title></title>
    
    <script runat="server">
        protected void Page_Load(object sender, EventArgs e)
        {
            Store1.DataSource = Enum.GetNames(typeof(Icon)).ToList().ConvertAll<object>(str => new { Icon = str });
            Store1.DataBind();
        }
    </script>
</head>
<body>
    <form id="Form1" runat="server">
        <ext:ResourceManager ID="ResourceManager1" runat="server" />
         
        <ext:Store ID="Store1" runat="server">
            <Reader>
                <ext:JsonReader>
                    <Fields>
                        <ext:RecordField Name="Icon" />
                    </Fields>
                </ext:JsonReader>
            </Reader>
        </ext:Store>
    </form>
</body>

    Enum.GetValues

    Hi,

    With values it can look something like this. (I'm not sure maybe there is some way to convert more effective).

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

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

<script runat="server">
    enum TestEnum
    {
        Test1 = 1,
        Test2 = 10,
        Test3 = 255
    }

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!X.IsAjaxRequest)
        {
            Store store = this.GridPanel1.GetStore();
            var list = Enum.GetNames(typeof(TestEnum)).ToList().ConvertAll<TestClass>(str => new TestClass { Name = str });
            
            var values = Enum.GetValues(typeof(TestEnum));
            int i = 0;
            list.ForEach(delegate(TestClass test) 
            {
                test.Value = ((int)values.GetValue(i++)).ToString();  
            });

            store.DataSource = list;
            store.DataBind();
        }
    }

    class TestClass
    {
        public string Name { get; set; }
        public string Value { get; set; }
    }
</script>

    This really is not an Ext.NET related issue.

    You just need to convert whatever it is to a List, then bind to the Store.

    Marking thread a [CLOSED].
