So I'm taking a few minutes - for my own sake - to write this stuff down so I can look it up next time I have a brain fart Using a Button Field you can specify a Command Name which in turn provides the On Row Command event some context as to what type of operation you are dealing with in Code Behind.

In Code Behind you have to do a bit of work though if you want to retrieve the proper context from a Data Item.

Sql Client, is simple, I've previously said that this cannot be done with Access and the Jet OLE DB provider without simply requerying the database.

I've recently discovered that this is not the case, so I decided to create a demo project to illustrate how it can be done.

I don't know about you, but I cringe every time I need to create a Grid View based layout that needs to create a few custom link handlers off that grid.

The typical scenario might be a list where you can toggle certain options or where you can fire an operation that otherwise updates the data that's underlying the grid.

NET 2.0 introduced a number of new Web controls designed for accessing and modifying data.

These controls allow page developers to declaratively access and modify data without writing any code to perform the data access. ) Because multiple users can visit the same web page concurrently, it is possible for a user visiting a data modification page to inadvertently overwrite the modifications made by another user. If two users visit this page simultaneously from different computers and both edit the same row, whomever saves the first will have her changes overwritten by whomever saves the row last.

Here's some code that needs to retrieve a Pk of one of the bound items and then perform some work on the data (in this case the business object): This seems like a lot of code to have to write just to retrieve data context.

The code first has to retrieve the Grid View Row, which is done by retrieving the Command Argument which in this case a row index of the rendered grid view items.

If it is commonplace for multiple users to be modifying the same set of data, you should consider implementing some form of concurrency control.
