Asp net gridview onrowupdating
Here is a simple example of using the View State to carry values between postbacks: Try running the project, enter your name in the textbox and press the first button. This one does nothing at all actually, it just posts back to the server.
The name will be saved in the View State and set to the Label as well. As you will notice, the Name Label still contains the name, but so does the textbox.
All this happens automatically, unless you turn it off, but you can actually use the View State for your own purposes as well.
Please keep in mind though, that while cookies and sessions can be accessed from all your pages on your website, View State values are not carried between pages.
Now let’s start with putting the Grid View on page. Data Key Names="Auto ID" Auto Generate Edit Button="True" On Row Editing="Edit Record" On Row Canceling Edit="Cancel Record" On Row Updating="Update Record" Cell Padding="4" Header Style-Horizontal Align="left" On Row Deleting="Delete Record" Row Style-Vertical Align="Top" Fore Color="#333333" Grid Lines="None" In the above code, I have kept Auto Generate Columns as false so that Grid View will not render all the fields of the data source automatically.
I have specified Data Key Names as Auto ID, the primary key of the database table.
In practical scenario you should use your existing architecture to populate and update the data.
In this article, I am going to take a simple database table that has following fields: Auto ID - Int, Auto Increment, Primary Key Page Name - Varchar(50) Page Description - Varchar(500) Active - Bit(1) In this article, I am not going to explain the workings of Sql objects but focusing on the events and methods of the Grid View that will help us in updating and deleting the records.
The Grid View control supports the following features:use Row Editing, Row Updating, Row Deleting, Row Command, Row Data Bound, Row Canceling Edit, and Pagination in a Data Grid.

Introduction The Grid View control displays the values of a data source in a table.
For demonstration I have created a database (named Database.mdf) in which we have a table named tbl_Employee.
Another approach to saving data for the user, is the View State.
