In this demo, I presumed that you already have a basic background on how to create a simple database table. Thanks that cmd do not work fine string id = Grid View1.
In this example, this time I used my own database called Sample DB which has Customers Table and basically contains the following field columns: As you have noticed in STEP 2, we have added six Text Box and a Button in the web form in order for us to type the information there and Insert them to the database.
The last parameter is a boolean value which tells the method whether to execute an Insert (false) or Update (true). In-order to perform Edit and Update in Grid View we need to use three events ( Grid View_Row Editing, Grid View_Row Canceling Edit , Grid View_Row Updating).

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.
Now let’s create a method for executing the Update or Insert.
