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

In data driven web sites, users are normally allowed to view data and administrators are allowed to add, edit or delete data.

This collection only requires the row index no and it will give us the primary key.

Last line of the following code is calling a local method for updating the database and passing all the parameters to this method.

Next event is the Grid View Row Editing event to give ASP. You need to set the Edit Index property of the Grid View with the New Edit Index property of the Grid View Edit Event Args class.

If user clicks the Cancel button while Grid View is in editing mode, you need to Cancel the Editing process and also need to reset the Edit Index property to -1 in the Row Canceling Edit event of the Grid View control as shown below: The last step is to handle the Row Updating event to actually update the back end database.

In this tutorial I will show you how you can create an editable Grid View control for administrators to modify database records directly into the Grid View control.

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: Before we start examining the ASP.

By Default, Grid View control displays Item Template which directly shows the Product Name and Unit Price columns but when user clicks Edit button Grid View automatically switches to Edit Item Template and display the control available inside Edit Item Template for user editing.

Now I will show you the C# code behind file of the above ASP.

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.
