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

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.

A couple of days ago I mentioned a project that I’ve been working on that is a bit out of the ordinary as far as Grid Views go.

One of the issues I’ve had is that the edit template doesn’t map to the view template very well. You see, the data that gets stored back to the database during the edit could go to two of four different tables.

None of them feels natural to me, so quite frequently - especially if I haven't written that code in a while - I spent way more time than I should rediscovering what approach I should use the hard way.

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.

The secret lies in the event handlers–in this case, the Row Updating event handler. Grid View Update Event Args object that is passed in.

Using the Row Updating handler, we can do whatever we want. What the line of code says is “cancel any other update processing that may have happened after this event gets called.” From here on out, you’ll need to retrieve the values from your edit controls manually using the Find Contro By ID() method I demonstrated on Monday and updating the database using code. – For a while now I’m trying to figure out why my method, triggered by the Grid View.

Major concern with any data entry form is Add, Edit, Delete and View.

It covers most of the basic reports for which you do not need any reporting component like Crystal Report, Report Viewer etc.

This calls for some extra coding from developer's end. As an example we are going to use Employees table of the Northwind database. Add three Bound Fields and a Command Field to the Grid View with the help of Fields dialog (see below).

In order to develop a test web form create a new web site in VS. Set various properties of the Bound Fields as shown in the following table: Here, we call Bind Grid() method if the web form is being served as a result of first request.

Template Field Colums have Item Template, Alternating Item Template, Edit Template, Header Template, Footer Template.
