System.Web.UI.WebControls Namespace   Repeater Class

---

Occurs when a button within a Repeater control is clicked.

[ VB ]
Public Event ItemCommand As RepeaterCommandEventHandler

[ C# ]
public event RepeaterCommandEventHandler ItemCommand;

[ C++ ]
public: __event RepeaterCommandEventHandler* ItemCommand;

In [ JScript ], you can handle the events defined by a class, but you cannot define your own.

The ItemCommand event is raised whenever any button associated with an item in the Repeater is clicked. This provides for programmatically determining which specific command button is clicked and take appropriate action. This event is commonly used to handle button controls with a given CommandName value in the Repeater control.

The method assigned to handle the event is passed a RepeaterCommandEventArgs object containing data related to the ItemCommand event. The following RepeaterCommandEventArgs properties provide information specific to this event.

Property	Description
CommandSource	Gets the source of the command.
Item	Gets the RepeaterItem associated with the event.

The following example illustrates a way to handle the ItemCommand event of a Repeater. Information about the selected item is displayed whenever any of the LinkButton controls within the Repeater is clicked.

The below snippet shows how to attach a handler for the event.

<asp:repeater id = "myRepeater" runat = "server" onItemCommand = "showItem" ... >

The below shows how the handler method is defined.

void showItem ( Object src, RepeaterCommandEventArgs e ) {  
   items.Text = e.Item.ItemType.ToString ( ) + " " + 
      e.Item.ItemIndex.ToString ( ) + ", " + 
    ( ( LinkButton ) e.CommandSource ).Text + "<br>";
}
