Default C# Ch 10 Page 362

After following the preceding try it out step by step, when I get to step 5 of the try it out on this page the business object i created in the previous try it out does not appear in the drop down menu of the wizard no matter what I do.

However the previous steps have been done correctly, as if I copy the code at the end of the try it out, the gridview correctly displays the data.

I am using visual web developer express 2008, any ideas?

Hi there,

Did you compile the application? For the objects to show up in the ODS wizard (if that's what you are talking about) you need to compile the application first.

HtH,

Hi,

I rebuilt the website after I created my business object. Do I need to do anything else to compile the business object?

Hi there,

If the objects are located in App_Data, then no, they are compiled together with the site. Sometimes reopening files or restarting VWD will help as well.

Maybe there is something wrong with your setup or with your site / setup? Here's what I just did and which worked fine:

1. Choose File | New Web Site. Create a new C# web site

2. Added a class called Product to App_Code

3. Inside that class create a new fake method called GetItems that returns List<Product>. The code simply throws an exception to satisfy the compiler.

4. Hit Ctrl+Shift+B to build the site.

5. Added an ODS to Default.aspx in Design View. Got the Product class as expected.

6. Added a new User Control to the site

7. Dragged the UC onto the Design View of Default.aspx. Worked as expected and were able to open the Smart Task panel of the UC.

AFAIK, this is all how it's supposed to work. It works for me every time.

Maybe your situation is different? (I don't have the book, so I don't know the exact steps. In that case, can you elaborate?

Imar

Hi Imar,

I have found the answer, and also the answer to my other problem!
It is a little bit stupid!

I was using a directory with part of the name being "c#".
Because the # was not a legal character for this it caused my problems. It also stopped the ASP.NET configuration tool from working.

As soon as I changed the directory name all the problems stopped occurring.
