Exceptions in ASP.NET Dynamic Data

I have an ASP.NET Dynamic Data application (using Entity Framework) in which I have just discovered a duplicate key error when attempting a database insert. However, I had to use SQL Profiler to find the error. The insert template page just silently did nothing.

How can I trap errors like this and log them and maybe display a message?

Solution

  • Exceptions can be detected, if not caught, in the CUD event arguments on the DetailsView and the DataSource controls, e.g. events such as DetailsView_ItemInserted, and DetailsDataSource_Inserting have Exception Exception and bool ExceptionHandled properties for handling exceptions.
