[Mono-aspnet-list] System.InvalidCastException with ScriptManager

Tue Feb 16 04:16:08 EST 2010

Hello everybody,

I am attempting to create a small test site using Mono and AJAX to test
ExtJS_Extender_Controls, with:
- Mono 2.6.1
- VS 2008
- Mono Tools 1.0
- ExtJs Extender Controls 3.3.0

The only page it has is:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs"
Inherits="Default" %>
<%@ Register Assembly="ExtExtenders" Namespace="ExtExtenders"
TagPrefix="cc1" %>

<!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 runat="server">
    <title>Untitled Page</title>
    <script>
        function renderRating(val){

            if(val > 8){
                return String.format('{0}',val);
            }
            else{
                return String.format('{0}',val);
            }

        }
        function DoClient() {
            alert("Menu clicked");
        }
    </script>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:ScriptManager ID="ScriptManager1" runat="server">
        </asp:ScriptManager>
        <div style="position:relative;top:20px;left:30px">
         <cc1:YuiGrid  ID="YuiGrid1"  AutoGenerateColumns="True"
EnableRowSorting="True"
                Width="550px" EnablePaging="True" PagingStyle="NavBar"
title="Movies"
                runat="server"
                AutoPostBack="true" CheckboxSelection="False"
                EnableBufferData="False" EnableEdit="False" Height="300px"
                SelectMultiple="False" >
       </cc1:YuiGrid>
      </div>
    </div>
    </form>
</body>
</html>

The solution builds right with VS2008 but when I try to run it in Mono:

Cannot cast from source type to destination type.

Description: HTTP 500. Error processing request.

Stack Trace:
System.InvalidCastException: Cannot cast from source type to destination
type.
