Hello everyone!
I am a beginner to ASP.NET
I have a problem with two nested datalists.
I have two data tables : Group (IdGroup,Group), Topic (IdTopic,Topic,IdGroup)

Now, I want to show data as follows:

<br />
A<br />
  A1<br />
  A2<br />
  A3<br />
B<br />
  B1<br />
  B2<br />
  B3<br />
C<br />
  C1<br />
  C2<br />
  C3<br />

I tried to use the ItemDataBound event but it does not run.
Hope you can help me. I am in need of help.

Here's an example I am doing http://www.mediafire.com/?iljmm2iinnm

Thanks for reading.
