LinkButton.Command Event

Occurs when the LinkButton control is clicked.

Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)

public event CommandEventHandler Command
/** @event */
public final void add_Command (CommandEventHandler value)

/** @event */
public final void remove_Command (CommandEventHandler value)

JScript supports the use of events, but not the declaration of new ones.

The Command event is raised when the LinkButton control is clicked. This event is commonly used when a command name, such as Sort, is associated with the LinkButton control. This allows you to create multiple LinkButton controls on a Web page and programmatically determine which LinkButton control is clicked.

NoteNote

The Command event is raised through the control hierarchy in the form of the BubbleEvent.

For more information about handling events, see Consuming Events.

The following example demonstrates how to specify and code a handler for the Click event to display a message when the LinkButton control is clicked.

<%@ Page Language="C#" AutoEventWireup="True" %>
<html>
<head>

   <script language="C#" runat="server">
     
      void LinkButton_Command(Object sender, CommandEventArgs e) 
      {
         Label1.Text = "You chose: " + e.CommandName + " Item " + e.CommandArgument;
      }
 
   </script>
 
</head>
<body>
 
   <form runat=server>
 
      <h3>LinkButton Command Event Example</h3>
  
      <asp:LinkButton id="LinkButton1" 
           Text="Order Item 10001"
           CommandName="Order" 
           CommandArgument="10001" 
           OnCommand="LinkButton_Command" 
           runat="server"/>
 
      <br>
  
      <asp:LinkButton id="LinkButton2" 
           Text="Order Item 10002"
           CommandName="Order" 
           CommandArgument="10002" 
           OnCommand="LinkButton_Command" 
           Runat="server"/>
 
      <br>
      <p>
 
      <asp:Label id="Label1" runat="server"/>
 
   </form>

</body>
</html>
