    Hi,

    Please look at the example.

    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)
        {
            Store store = this.GridPanel1.GetStore();
            store.DataSource = new object[] 
            { 
                new object[] { "test1" },
                new object[] { "test2" },
                new object[] { "test3" }
            };
            store.DataBind();
        }
    }
</script>
