Visual C# 2005 Databinding to UI tutorial

[Peter Gloor]

Hello,

I have some difficulties to understand the new concepts for data handling
and data access in Visual C# 2005 Windows applications.

The questions are when and how to use which component and how they releate
to each other.

I have no problem to understand the various examples and to write my own
application that displays data read from an SQL database. I even manage to
create a button to call a form to be filled-in which contains a button to
add the data to the SQL database.

However, if it comes to a little more complicated real-life application I
don't manage to get updates and deletes properly done.

Where can I find a tutorial, a book or examples that explains the new
compontents in detail and how to use them in various scenarios.

Thank you.

Peter

Hi Peter,

First of all, I would like to confirm my understanding of your issue. From
your description, I understand that you need to get some tutorial on new
features on ado.net 2.0. If there is any misunderstanding, please feel free
to let me know.

Generally the features in ado.net 1.1 are supported in ado.net 2.0, because
of backward compatibility. Also, there are many new features in ado.net
2.0. For example:

Server Enumeration
Asynchronous Processing
Multiple Active Result Sets (MARS)

Also for windows form databinding, you can check the following link. It's a
detailed tutorial.

HTH.

Hi Kevin,

Thank you. It's exactly what I was looking for.

Meanwhile I found that the "Absolute Beginner's Video Series to Visual
Studio 2005 Express Editions" tutorials at
http://lab.msdn.microsoft.com/express/beginner/ have been updated as well
and got two chapters related to ADO.net (it ended at chapter 6 last time I
visted the site).

However, using Visual C# 2005 Express Edition I still have some problems
with data editing (Data Tables) but at least I understand now the concepts
and I learned how things are related to each other. My problem is that data
wont write back for some reason and if I change my code I get a lot of
errors I don't know how to deal with.

For the moment it's ok for me. I will take what's there and what works even
my solution is not so elegant as it probably could be.

Peter
