Edit a Custom Control (IIS 7)

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

Edit a local custom control when the prefix, namespace, or assembly for the custom control has changed.

Editing a configuration setting changes the setting at the local level and for any child levels that inherit the setting.

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

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.

  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 control that you want to change, and then click Edit in the Actions pane.

  5. To change the tag prefix, in the Edit Custom Control dialog box, type a new tag prefix in the Tag prefix text box.

  6. To change the namespace, type a new namespace in the Namespace text box.

  7. To change the assembly, type the name of the source or assembly for the custom control in the Assembly text box, and then click OK.

To change the tag prefix of a custom control, use the following syntax:

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

A tag prefix is the value that is mapped to a source file or namespace and assembly. The first variable tagPrefix string is the tag prefix that you want to change, and the second variable tagPrefix string is the new value.

For example, to change the tag prefix from MyTag to MyTestTag, type the following at the command prompt, and then press ENTER:

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

To change the namespace for a custom control, use the following syntax:

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

The namespace is the value that is associated with the tag prefix. The first variable namespace string is the namespace that you want to change, and the second variable namespace string is the new value.

To change the assembly for a custom control, use the following syntax:

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

The assembly name is the value of the assembly that contains the COM control implementation. The first variable assembly string is the assembly name that you want to change and the second variable assembly string is the new value.

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).

The procedure in this topic affects the following configuration elements:

  • <controls>

For more information about IIS 7 configuration, see IIS 7.0: IIS Settings Schema on MSDN.

Use the following WMI classes, methods, or properties to perform this procedure:

  • PagesSection.Controls property
