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

abstract CommandArgument : string with get, set
override CommandArgument : string with get, set
<asp:Button CommandArgument="String" />

Property Value

Type: System.String
An optional parameter passed to the Command event along with the associated CommandName. The default value is String.Empty.



Use the CommandArgument property to specify a parameter that compliments the CommandName property.


Although you can set the CommandArgument property by itself, it is normally only used when the CommandName property is also set.

The CommandArgument property complements the CommandName property by allowing you to provide additional information about the command to perform. For example, if you set the CommandName property to Sort and the CommandArgument property to Ascending, you specify a command to sort in ascending order.

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

The following code example demonstrates how to use the CommandArgument property to create a Button control that sorts a list in ascending order.
