Multitier application and Datagrid

[André Wagner]

Hello,

I'm trying to understand how can I write a application in three layers
and use a datagrid on a object.

For example, let's say I have a table on my database (COUNTRIES) with
the fields ID and DESCRIPTION. And I have a class Country that would
connect to this table:

class Country
{
public int ID { get; set; }
public string Description { get; set; }
}

Now, I know I can create a data source out of this object and connect
it to a datagrid. But how then can I handle things updates, inserts
and deletions in the datagrid?

Thank you in advance,

André

One word - "ObjectDataSource".

But: I'm not using ASP. Can I use ObjectDataSource with just C#?

You're kidding, right?

[André Wagner]

Ok.

I mean: an example not in ASP. Check the Google results, you'll see
that all pages return examples in ASP. What I'm looking for is an
example in a desktop application.

No, I'm not. I searched all examples in MSDN, and looked for it
everywhere in Google and couldn't find one example of ObjectDataSource
that's used in a desktop application and not ASP.

At last you've used the word "desktop application". All along you've
been saying "ObjectDatasource with C#", which tells us nothing.

No, I don't think you can use ObjectDataSource (the control) with
windows forms, and then you would never need to, because windows forms
has different ways of Databinding.

1. Google "BindingSource", "BindingNavigator", "TableAdapter".

2. Open the Datasources window and click "Add new Datasource" and
provide the path to your Data access layer. Of course, your datalayer
will need to confirm to certain standards. Read up some docs or how-
to's.
