ObjectListShowCommandsEventArgs Class

Provides data for the ShowItemCommands event of an ObjectList control.

public class System.Web.UI.MobileControls.ObjectListShowCommandsEventArgs
   : System.EventArgs

Remarks

An instance of a ObjectListShowCommandsEventArgs object is automatically created and passed to the event handler for the ShowItemCommands event of an ObjectList control.

An inherited class or event handler can use this event to show commands unique to the item, by changing the collection of commands in the Commands property.

Example

The OnShowItemCommands event calls a user-defined event handler called SelectCommand. One of the parameters for this event handler is the ObjectListShowCommandsEventArgs object used in a conditional statement.
