Raises the DataList.UpdateCommand event. This allows you to provide a custom handler for the event.
Syntax
Parameters
- e
Remarks
Use the DataList.OnUpdateCommand(DataListCommandEventArgs) method to provide a custom handler for the DataList.UpdateCommand event.
The DataList.UpdateCommand event is raised when the Update button for an item is clicked.
A typical handler for the DataList.UpdateCommand event updates the data, sets the DataList.EditItemIndex property to -1 (to deselect the item), and then rebinds the data to the System.Web.UI.WebControls.DataList control.
This control can be used to display user input, which might include malicious client script. Check any information that is sent from a client for executable script, SQL statements, or other code before displaying it in your application. You can use validation controls to verify user input before displaying the input text in a control. ASP.NET provides an input request validation feature to block script and HTML in user input. For more information, see Securing Standard Controls, How to: Protect Against Script Exploits in a Web Application by Applying HTML Encoding to Strings, and Introduction to Validating User Input in ASP.NET Web Pages.
Raising an event invokes the event handler through a delegate. For more information, see How to: Consume Events in a Web Forms Application.
The DataList.OnUpdateCommand(DataListCommandEventArgs) method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
