CommandName Property

LinkButton.CommandName Property

Gets or sets the command name associated with the LinkButton control. This value is passed to the Command event handler along with the CommandArgument property.

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

[ThemeableAttribute(false)] 
public string CommandName { get; set; }
/** @property */
public final String get_CommandName ()

/** @property */
public final void set_CommandName (String value)

public final function get CommandName () : String

public final function set CommandName (value : String)

Property Value

The command name of the LinkButton control. The default value is String.Empty.

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 Overview.

The following example demonstrates how to use the CommandName property to specify a command name for a LinkButton control.

<%@ 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"
