Thanks Marc,

                    I also got it working the same way.I think there is some problem with NetAdvantage for .NET 2008 Vol. 3 CLR 3.5 and Visual Studio 2008 (.NET 3.5)

Hi,

I had exactly the same problem, try these steps to copy the files locally to your project:

(1)  Copy WebSchedule Folder from the following path  "C:\Inetpub\wwwroot\aspnet_client\Infragistics\20091CLR35\Forms"  to your application level.
(2)  Optionally rename the copied WebSchedule folder to "Forms"
(3)  Create an App_Code folder on Visual Studio if it does not exist
(4)  From your local Forms folder (from step 2), open the App_Code folder and copy
            the following 2 files:
                        MCListBox.cs
                        ComboBox.cs
            to the App_Code folder of your application (the one created on step 2)
(5) Copy the App_GlobalResources file to you application level from your "Forms" folder
(6)  Delete the Local Form's App_Code, Bin, App_GlobalResources and Web.Config.
(7)  Redirect the web.config to point to the Forms directory like given below:
    <infragistics.web formsDirectory="~/Forms">

Worked for me

Make sure the dialog page is installed in the correct place and that the pointer to the location is typed correctly. I had this same problem with infragistics when I installed it I kept getting that 404 error no matter what I did. Finally I changed the location of the dialog page and told it to open one I created myself. Worked like a charm after that.

I am using File System .I get this error.
