String was not recognized as a valid DateTime???


Dennis McCarthy

I have an aspx page that contains a GridView which is data bound to an
ObjectDataSource. The ObjectDataSource is calling the class generated by a
web reference. When the page loads and the ObjectDataSource calls a method
in the web reference class, I get the exception included below. The
ObjectDataSource is getting the date from a Calendar control, so it is valid.

How can I set a breakpoint in the client proxy method that is generated for
the web reference, so that I can see the value. There is no source code file
added to my project when I add the web reference.
