Hey guys,
I am trying to create a pretty straightforward webschedule page and I keep getting this:
An exception of type 'System.ArgumentNullException' occurred in System.Web.dll but was not handled in user codeAdditional information: Value cannot be null.
The odd thing is that when I set up the webschedule stuff in another (simple) project, it works. I use the same SqlDataSource and WebScheduleSqlClientProvider. The only difference is that in the first project, I'm using the supervising controller pattern and having the controller make a call to the view's DataBind method when the page loads and that's where the exception gets thrown.
Any help would be greatly appreciated.
Thanks,
Ilija
Edit:
When I remove the call to DataBind, I end up with this error:
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)

The strange thing about this is that I'm using the exact same connection string as in the other project and it works in that one...
Looks like WebSchedule doesn't like MatserPages.
I created a page without using a master page and it works.
I created a different page that uses a master page and it throws this error.
The only difference between pages is that one uses a MasterPage and the other one doesn't.

I have exactly same issue.
I have a project with WebMonthView. I'm trying to hook it to SQL database. It gives me the error above.
I went ahead and created a sample application and did EXACTLY the same thing, same code same connection string. This sample application WORKS.
What is going on here?
