Dataset updating row
I tried hard to use one of the Data Source objects to update a Data Set, but was not able to do this. Text where e is the eventargs parameter passed to the updating event. Well, you'll just have to go through the controls collection of each cell to get a reference to the controls placed inside it. What I'm trying to understand is why the New Values/Old Values/Keys properties of the Event Args parameter are populated when using one of the built in data sources, but not when manually binding a Data Set to the Grid View. well, it's just one of the things that stop working when you don't use the data source controls.

After your dataset is populated with data, you will typically perform some kind of manipulation of the data before sending it back to the data source or to another process or application.
Since each record in a dataset is represented by a Data Row object, changes to a dataset are accomplished by updating and deleting individual rows.
In his second example, he's setting the entire Item Array property to a new object array (almost. In your example, you're indexing into the object returned by the Item Array property and setting element 12 to be "Contact Customer Service".

Since Item Array is returning a copy of the items in the Data Row, your code is just updating the copy. Trim())When I check the Data Set to see if there are any changes or if therowstate has chaned, neither have changed. I have found two or three places where it states that to update anitemin a dataset, all I have to do is do Data Set.
I'm trying to update a Data Set object with a Grid View. We have a 3-tier architecture with strict boundaries. This means that communication between UI components and Business components is done by means of a Data Set.
Then, it's indexing into that row's columns to get the column at index 1 and is assigning the value to that column. Item Array = new object ; Obviously, the first approach is much simpler in your case ;) -- Dave Sexton "samoore" Cor I do that, or at least I think I do that.
