      }

   <form id="form1" 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 />
      <br />
 
      <asp:Label id="Label1" runat="server"/>
 
   </form>

</body>
</html>

Remarks

When you have multiple LinkButton controls on a Web page, use the CommandName property to specify or determine the command name associated with the LinkButton control clicked. You can set the CommandName property with any string that identifies the command to perform. You can then programmatically determine the command name of the LinkButton control and perform the appropriate actions.

Additional information about the command, such as an Ascending sort order, can be specified by using the CommandArgument property.

This property cannot be set by themes or style sheet themes. For more information, see ThemeableAttribute and ASP.NET Themes and Skins.
