Gridview onrowupdating

This example shows how to edit and update records in a Grid View in ASP. This example is helpful in situations where an administrator needs to edit several records from the database.

We can achieve the same functionality using Datakeys. Row Updating event, doesn’t work as all samples say it should do.All samples of course assume you’re doing everything in your page, but I have to do everything in my code-behind, because on forehand I don’t know what I’ll be binding to my Grid View.In this example, I am going to retrieve values from categories table of Northwind database. Drag a Grid View into the Web Form and assign Data Key Names property with the primary key column i.e. In the gdview_Row Editing and gdview_Row Deleting event, we have used the below code to retrieve categoryid from datakey of Grid View, int catid = int.
