Datasource config wizard cant find business object?6/30/2004 5:58:55 PM

0/0

This part of the guide:
http://beta.asp.net/GuidedTour/s13.aspx

tells you to insert an ObjectDataSource which should then list the DataAccess class in the business objects dropdown. However, it is refusing to list the class for me.
I built the class by copying and pasting it from the guide.

Has anyone else got this working ?
Thanks.

I ran into the same problem.
I am using the C# code instead of the vb code.
It appears that the problem is that the code supplied is wrong. When you try to build the site, you get an error stating:
Cannot implicitly convert type 'System.Data.CommandType' to 'string C:\WebSites\Authors\Code\AccessData.cs

Unfortunatly, I am a newbie at programing, so I have no idea how to fix the problem.

What I did to "fix" the problem was to create the webpage using vb. This will create further problems because you can't mix code types.

I run into the same problem but with my own class. There was an error in my class, so what I did was to fix the problem and run the code so the runtime compile the class in my \Code folder (only to be sure that everything works fine). After that I could see my class.

Not sure if any one else is still experiencing the problem, but I found in the C# Code the line

command.CommandText = CommandType.Text; (line 18 and 40)

should really read

command.CommandType = CommandType.Text;

after that fix, I could see the objects in the dropdown.

You won't be able to see the objects unless they can compile. :D

Someone should update those Quickstarts.

Is this something in the Guided Tour or the Quickstarts? Can you point me to the exact page the problem is on? We'll get it fixed once we know.

Thanks,
Brian

The C# file available for download is wrong: http://beta.asp.net/GuidedTour/s11.aspx

Which means the step provided at this link won't work correctly:

Line 45 in the VB version of the DataAccess.vb file is wrong.

command.Parameters.Add(New SqlParameter("@original_id", SqlDbType.VarChar, 11)).Value = original_au_id

should be...

command.Parameters.Add(New SqlParameter("@original_id", SqlDbType.VarChar, 11)).Value = au_id

Once you correct that and build the web site then the ObjectDataSource will see the DataAccess object.

Thanks, MojoMoto
I was getting the same problem and couldn't solve it. Hopefully I can now carry on with the tour. Thanks again.

We should have an online Readme where we could post a list of fixes for source code.
The Readme would always appear at the top of the Forum. For each Forum that provides source.

I ran into this problem today and I just downloaded the file about an hour ago. Usually something like this takes HOURS to pin down and resolve. I got REAL lucky this time. When I logged on to the forum it was only a little ways down the list so I didn't have to search all over creation. Thanks to the person who found the error in the code and then POSTED THE ANSWER here. Bless you. Bless you. Bless you!
