Context menus

 

When editing transformations displaying Users or Groups, you can enclose the transformation code within one of the following controls, which enables context menus after a right-click on the selected user or group:

 

Users

 

 

Groups

•GroupContextMenu.ascx

•UserContextMenu.ascx

 

You can also develop your custom controls for this purpose. In this case, you need to include the MenuControlPath parameter in the cms:usermenucontainer or cms:groupmenucontainer controls in the transformation and set its value to the path to your control:
