Can I somehow place a breakpoint in

Hi Marc,

simply go to MSDN and find that

1) NotSupportedExc eption happens when the ExecuteDelete operation is
not supported by the DataSourceView.

2) The DataSourceView class's default implementation is to throw a
NotSupportedExc eption exception. If you extend the DataSourceView
class, override the ExecuteDelete method if your class supports
deletion from the underlying data storage.

3) Data-bound controls can determine whether the ExecuteDelete
operation is supported by a data source control by retrieving the
DataSourceView object using the DataSourceContr ol..::.GetView method,
and checking the CanDelete property.

DataSourceView.ExecuteDelete(IDictionary, IDictionary) Method (System.Web.UI)

http://msdn.microsoft.com/en-us/library/system.web.ui.datasourceview.executedelete.aspx

Performs a delete operation on the list of data that the DataSourceView object represents.

Hope this helps

Well it helps solving the programming problem I had, but that was not really
my question. Sorry to see you go to all that trouble for nothing. At this
moment I am programming with some other tools then C# and ASP.NET and for
example in Delphi you can see the vcl library code in c:program
files\borland\d elph\source\vcl and step through it. I wondered if could do
that with some parts of the .NET framework too.

Your post does help the coding problem by the way, it was not for nothing,
but this exception is another problem. I excuse myself for not being clear.

Well, I thought you wanted to solve the problem at first :-) You can
debug .NET and you can also get access to its source code. Please take
a look at the following references:

The resource cannot be found.

Hello Mark:
You can see framework's source using tools as Ildasm.exe to see the
result as IL code, or Reflector http://www.aisto.com/roeder/dotnet/
wich let you choose the language, including Delphi.Net ;-)

Is it possible to debug the framework code?
