The described behavior is by design. Every template is associated with a given .master
page located in ~/App_Master
folder. Normally, after deleting the .master
page, an exception should be thrown. The workaround is to delete the corresponding template using the deleted .master
page as well.
Regarding the second issue, you can rename the template, but you cannot associate it with a different .master
For more information on this matter, please, refer to the User Manual
, chapter Working with Page Templates
Hope this is helpful for you.
