System.Web.UI.WebControls Namespace GridView Class
.NET Framework version 2.0
Occurs when a Delete command button within a GridView control is clicked, but before the delete operation.
[ VB ]
Public Event RowDeleting As GridViewDeleteEventHandler
[ C# ]
public event GridViewDeleteEventHandler RowDeleting;
[ C++ ]
public: __event GridViewDeleteEventHandler* RowDeleting;
In [ JScript ], you can handle the events defined by a class, but you cannot define your own.
The RowDeleting event is raised whenever a Delete button associated with an item in the GridView control is clicked, but before the GridView control deletes the record.
This allows you to provide an event-handling method that performs a custom routine, such as verifying a record before deleting it, whenever this event occurs.
Information related to the RowDeleting event is passed via a GridViewDeleteEventArgs object to the method assigned to handle the event. The following GridViewDeleteEventArgs properties provide information specific to this event.
| Property |
Description |
| Cancel |
Gets or sets a value indicating whether the event should be canceled ( inherited from CancelEventArgs ) |
| Keys |
Gets an ordered dictionary of key field name/value pairs for the record to delete. |
| RowIndex |
Gets the index of the record being deleted from the data source. |
| Values |
Gets a dictionary of the non-key field name/value pairs for the item to delete. |
The following example demonstrates how to code a handler for the RowDeleting event to delete a single item from a GridView control.
WARNING: Deleting rows in a database table CANNOT BE UNDONE, which can result in serious data loss. In a real-world scenario, only the database administrator or an authorized user must be granted DELETE permission. The examples provided here are only for learning purposes.
