Hi,
I'm working on a WebService project. I'm trying to validate data before they
are updated to the database by handling the RowUpdating event for a
SqlDataAdapter.
The data being handled has DataRelation which is related to another
DataTable. As for that, I also need to retrieve the DataRelation from the
current row being updated. I wrote a code which look something like this,
Dim relation As DataRelation
For Each relation In e.Row.Table.Chi ldRelations
Dim rows As DataRow()
' e.Row.GetChildR ows(relation) will always return nothing
rows = e.Row.GetChildR ows(relation)
Next
If you try this code, e.Row.GetChildR ows(relation) will always return
nothing even though the DataTable which contains the DataRow has
DataRelation.
Beside that, the e.Row.HasErrors and e.Row.RowError properties will also
return nothing.
Is this a bug in .NET Framework 1.1 or I need to change the coding.
Thanks.

I've finally found where the problem lies. It's my fault actually. When I
asked the SqlDataAdapter to update to database, I used the following
overloaded Update method,
Overloads Public Function Update(DataTabl e) As Integer
Because of this, the information included in the DataSet is not included in
the RowUpdating event.
The original idea to use DataTable instead of DataSet is because in my
opinion, sending the DataTable will be faster than DataSet, but it seems to
produce more problem than I have ever thought of.
Sigh...
Thanks for reading.

Why is it not related to VB .Net? I'm using VB .Net to write the code. As
for that, it should be related to VB .Net.

Still sometime, anyone with VB skill could have known the solution and that
someone, since always used VB only browse the VB newsgroup, might not browse
the ADO .Net newsgroup. And in this case, that someone might not know that
his/her help is needed.

Would it be the same question in C#? If yes, it's not related to VB. As
the subject (and the question) shows, it's a about ADO.Net and the Framework
class library, no matter which language you use. So it's not a VB.Net
related question, IMHO.

Then you should also post to alt.binaries.ca rtoons.french because there
might be someone who can help you. ;-)

Depends on whether you want a good answer, or any answer.
I actually skimmed by this yesterday because I was in a rush and saw that
Armin had answered you.
Good that you answered your question, but I think crossposting rarely helps
you get the answer your looking for (except when the issue lies on teh seam
between multiple groups).

In my case now, I want any answer.
Anyway, enough is enough. There is no need for arguement here. Armin has his
point but sometime, that someone needed a quick respond and any responds are
considered good, even though it's not.

I am using a SQLDataSource to populate my gridview in ASP.Net 2.0. When I hit Edit, the textboxes appear and I am able to edit my values. When I hit Update, the changes are not saved, and there is no error message. I put a breakpoint on the RowUpdating event handler and found that the event is not fired. Right now, I have not written code for the Update event. I am just wondering why the event is not firing. Here Person_ID is the primary key....

Which is the event sequence when a gridview button (for update) is clicked
and the page is post back? I am also a bit confused when to use
..IsPostBack(). If my page data is changing maybe in every 10 or 20 seconds,
should I use .IsPostback? If not, then the gridviews databinding in the page
should be written in Page_Load or in the other events like
SelectedIndexChanged, RowCommand where the click is handled?
TIA
