Gridview rowupdating in asp net example dating telegramm com

In this article, we will explore how to add, update, delete and select a record from sql server database using gridview control in a simple way.

I’m using visual studio 2008 and sql server 2008 for this sample.

A Grid View Update Event Args object is passed to the event-handling method, which enables you to determine the index of the current row and to indicate that the update operation should be canceled.

To cancel the update operation, set the collections, if necessary, before the values are passed to the data source.

You need to include the Grid View Command Field column to add Edit, Update and Cancel Buttons in the Grid View. You need to include Template Field for every column you want to provide Editing because Template Field provides you both Item Template and Edit Item Template to create interface for two separate Grid View modes. You need to handle Grid View events such as Row Editing, Row Canceling Edit and Row Updating to provide desired editing functionality.

Font-Names="Verdana" Font-Size="10" Data Key Names="Product ID" Auto Generate Columns="false" onrowcancelingedit="Grid View1_Row Canceling Edit" onrowediting="Grid View1_Row Editing" onrowupdating="Grid View1_Row Updating"In the above code, I set two properties Show Edit Button and Show Cancel Button of Command Field.

Note A common mistake that a lot of people do is that they perform a databind each and every-time the Page_Load method is called.

I am using Template Field’s Item Template and Edit Item Template for providing read only and editing interface of the same column in the Grid View.

before that i want just using Find control and casting and then retrieving all lot code. If values are same they could notify user to change the value(give new cell value).

Every one can use it to compare the new value with old ones.

There are multiple ways in which one can get the data from the current row that is being edited in a Grid View. Using "Extract Values From Cell": This is an easy way to get all the values from the current row.

In my case this was happening because I was binding to a List of custom objects.
