Please note that when you will not bind the data again, Grid View will not change in edit mode.When Cancel link is clicked on Grid View in edit mode, On Row Canceling Edit event will fire that will call Cancel Record method.

This will make sure that Bind Data() method will not fire when you are going to edit, update or delete the record.

In Bind Data() method, I am getting the data from database using Sql objects and specifying the Data Source property of the Grid View to the Pages Data table of the Data Set.

To get the Primary key, I have used Data Keys property of the Grid View with the index of the row, being edited and stored into a integer variable after parsing.

Now I have declared a Grid View Row variable named row and stored the current row being edited into it.

When I do an update, and get to the Grid View1_Row Updating, there is no value passed to "ID", and then when I go to the next row for "Company" I get the following error: Specified argument was out of the range of valid values.

Text; bit when ichange it to string id =((Text Box) Grid View1.So I have to specify how I want them to appear in the normal view and edit view.That’s why I have placed different templates like Item Template (for normal view) and Edit Item Template (for edit view).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.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.You can notice that I have kept Required Field Validator too inside the Edit Item Template as I want the textbox to be validated for empty data.In the same way you can put any kind of Validation controls inside Edit Item Template to validate the form element while user will click Update link.When Update link of the Grid View will be clicked (in edit mode), On Row Updating event will fire that will call Update Record method.In this method, we have to get changed values of Text Box and Drop Down list and also we need the primary key value for the record that is being edited.With the help row variable, I am going to find all the controls placed under that row in edit mode using Find Control property.After finding the controls I am using them to pass their values to the parameter of the Sql Command object that is ultimately updating the records into database.
