Hi, I am relatively new to ASP.NET and I am experimenting with some code and
exercises.
My question: Say I have some stacktrace because I have some error.
[NotSupportedExc eption: Specified method is not supported.]
System.Web.UI.D ataSourceView.E xecuteDelete(ID ictionary keys, IDictionary
oldValues) +28
System.Web.UI.D ataSourceView.D elete(IDictiona ry keys, IDictionary
oldValues, DataSourceViewO perationCallbac k callback) +75
System.Web.UI.W ebControls.Grid View.HandleDele te(GridViewRow row, Int32
rowIndex) +927
System.Web.UI.W ebControls.Grid View.HandleEven t(EventArgs e, Boolean
causesValidatio n, String validationGroup ) +1134
System.Web.UI.W ebControls.Grid View.RaisePostB ackEvent(String
eventArgument) +199
System.Web.UI.W ebControls.Grid View.System.Web .UI.IPostBackEv entHandler.Rais ePostBackEvent( String
eventArgument) +7
System.Web.UI.P age.RaisePostBa ckEvent(IPostBa ckEventHandler
sourceControl, String eventArgument) +11

System.Web.UI.P age.ProcessRequ estMain(Boolean
includeStagesBe foreAsyncPoint, Boolean includeStagesAf terAsyncPoint) +1746
Can I somehow place a breakpoint in
'System.Web.UI. DataSourceView. ExecuteDelete' and look at what is happening
there?
(Well, I think, probably not since the code for the framework is not shipped
as far as I can see.)

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. http://msdn.microsoft.com/en-us/libr...utedelete.aspx
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: http://weblogs.asp.net/scottgu/archi...libraries.aspx http://blogs.msdn.com/sburke/archive...urce-code.aspx

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 ;-) This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |
