    [CLOSED] GridView - Locking and Multi Header

    Hi,

    In my attached example, I've created 3 examples.
    1.) Multi-Header GridPanel
    2.) GridPanel with the first column locked
    3.) 1 and 2 combined.

    Results:
    1.) I'm able to display multiple headers
    2.) I'm able to lock the first column
    3.) No object is displayed

    My question is:
    Can one combine the 2 together?

    Hi,

    Thanks for the excellent example.

    But, unfortunately, LockingGridView and Multi Headers features are incompatible with each other.
    http://forums.ext.net/showthread.php...ll=1#post55258

    This problem has been resolved in Ext.NET v2.

    Example Ext.NET v2
    <%@ 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)
        {
            this.Store1.DataSource = new object[]
            {
