Remove a Custom Control (IIS 7)

Applies To: Windows 7, Windows Server 2008, Windows Server 2008 R2, Windows Vista

Remove a custom control when the custom control will no longer be used in multiple pages in an application. You can remove a custom control at a local level or you can remove a custom error that is inherited from a parent level.


For information about the levels at which you can perform this procedure, and the modules, handlers, and permissions that are required to perform this procedure, see Custom Controls Feature Requirements (IIS 7).

Exceptions to feature requirements

  • None

To remove a custom control

You can perform this procedure by using the user interface (UI), by running Appcmd.exe commands in a command-line window, by editing configuration files directly, or by writing WMI scripts.

User Interface

To Use the UI

  1. Open IIS Manager and navigate to the level you want to manage. For information about opening IIS Manager, see Open IIS Manager (IIS 7). For information about navigating to locations in the UI, see Navigation in IIS Manager (IIS 7).

  2. In Features View, double-click Pages and Controls.

  3. In the Actions pane, click Register Controls.

  4. On the Controls page, select the custom control you want to remove, click Remove in the Actions pane, and then click Yes.

Command Line

To remove a custom control, use the following syntax:

appcmd set config /commit:WEBROOT /section:system.web/pages /-"controls.[tagPrefix='string']"

The variable tagPrefix string is the tag prefix that is being mapped to a source file or namespace and assembly. For example, to remove a custom control that has the tagPrefix "MyTag", type the following at the command prompt, and then press Enter:

appcmd set config /commit:WEBROOT /section:system.web/pages /-"controls.[tagPrefix='MyTag']"


When you use Appcmd.exe to configure the <controls> element at the global level in IIS 7, you must specify /commit:WEBROOT in the command so that configuration changes are made to the root Web.config file instead of ApplicationHost.config.

For more information about Appcmd.exe, see Appcmd.exe (IIS 7).
