  • Reference

Definition

Namespace:

Assembly:
System.Web.Mobile.dll

Occurs when a user activates a Command control. This API is obsolete. For information about how to develop ASP.NET mobile applications, see Mobile Apps & Sites with ASP.NET.

public event EventHandler Click;
member this.Click : EventHandler 
Public Custom Event Click As EventHandler

Event Type

EventHandler

Examples

The following code example demonstrates how to attach command events. Clicking either of the Command buttons raises the OnItemCommand event. The user-defined function uses the CommandEventArgs argument to see which Command button was clicked.

Note

The following code example uses the single-file code model and may not work correctly if copied directly into a code-behind file. This code example must be copied into an empty text file that has an .aspx extension. For more information on the Web Forms code model, see ASP.NET Web Forms Page Code Model.
