You can leave a response, or trackback from your own site.So once after done with editing data, if we click update the following method will be triggered. Once we access the required fields in the code behind, we need to update the data in the database and show the updated data to the user. If the user clicks the Delete button On Row Deleting event will be fired. Going into that code we are trying to get the primary key of the employee table(Employee ID) by using Grid View Data Key Names and then This entry was posted on March 27, 2009 at am and is filed under ASP.

Now from the smart tag of the Grid View choose “Edit Template” and then select “Edit Item Template” of Company Name column.
This will display the template designer for the column as shown in Figure 6.
