This will lead to problems like "Grid View does not show updated values", "Grid View looses values changed by user". In your Page_load, this is typically only inside a block where you check to make sure that Page_Load is not being called during a post-back call.

The visitors to a web site can typically be divided into two groups: the users and the administrators.

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.

These properties will automatically render Edit, Update and Cancel buttons inside Grid View column.

Editing the Grid View control can be an incredibly easy feature to add for certain database tables, especially those who have no foreign key associated and can easily be edited through the use of a standard Text Box web control as shown in the figure below: 1.

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.

This enables you to provide an event-handling method that performs a custom routine, such as canceling the update operation, whenever this event occurs.

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.
