hi,
I have a page with a HtmlEditor control.When I use window.showModalDialog to pop up this page,I found the HtmlEditor can not edit.

Page1.aspx
<body>
    <form id="form1" runat="server">
    
        <ext:ScriptManager ID="ScriptManager1" runat="server" />
        <ext:HtmlEditor ID="txtHtmlEditor" runat="server"></ext:HtmlEditor>
    

    </form>
</body>
Page2.aspx
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    
          <ext:ScriptManager ID="ScriptManager1" runat="server" />
          <ext:Button ID="btnPopup" runat="server">
                  <AjaxEvents>
                        <Click OnEvent="btnPopup_Click"  ViewStateMode="Include"/>
                    </AjaxEvents>
          </ext:Button>
    

    </form>
</body>
</html>
protected void btnPopup_Click(object sender, AjaxEventArgs e)
{
    string scriptContent = "var sPopupWindowUrl = 'http://localhost/page1.aspx';\r\n"
        + "var sFeatures='resizable: no; status: yes; scroll: yes; help: no; center: yes; dialogWidth : 670px; dialogHeight : 660px;';\r\n "
        + "var passingArgs = null;\r\n\r\n"
        + "var rv=window.showModalDialog(sPopupWindowUrl, passingArgs, sFeatures);";
    Coolite.Ext.Web.ScriptManager.GetInstance(Page).AddScript(scriptContent);
}
