Thetype exposes the following members.
|Cancel||Gets or sets a value indicating whether the event should be canceled. (Inherited from CancelEventArgs.)|
|Keys||Gets a dictionary of field name/value pairs that represent the primary key of the row to update.|
|NewValues||Gets a dictionary containing the revised values of the non-key field name/value pairs in the row to update.|
|OldValues||Gets a dictionary containing the original field name/value pairs in the row to update.|
|RowIndex||Gets the index of the row being updated.|
|Equals(Object)||Determines whether the specified object is equal to the current object. (Inherited from Object.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)|
|GetHashCode||Serves as the default hash function. (Inherited from Object.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|

The GridView control raises the RowUpdating event when a row's Update button is clicked, but before the GridView control updates the row. This allows you to provide an event-handling method that performs a custom routine, such as canceling the update operation, whenever this event occurs.
A object is passed to the event-handling method, which allows you to determine the index of the current row and to indicate that the update operation should be canceled. To cancel the update operation, set the Cancel property of the object to true. You can also manipulate the Keys, OldValues, and NewValues collections, if necessary, before the values are passed to the data source. A common way to use these collections is to HTML-encode the values supplied by the user before they are stored in the data source. This helps to prevent script injection attacks.
