Page templates and layout files
Each website has one or more default layout files that define the general structural division of pages into sections. A layout file and its section placeholders serve as the basis, on which Sitefinity CMS and the view engines construct views and render the proper markup.
A layout file is the physical file residing in the file system as opposed to the page templates, based on this layout file. You work with page templates in the Sitefinity CMS backend .
Depending on which mode you are working in, the layout files can be:
- .cshtml layout files (MVC only templates)
- .master file or .ascx page template files (hybrid and Web Forms only templates) -> when you base page template son the master file(s), they are stored in the database but are not physical files; do not need to map them to files like with MVC templates
RECOMMENDATION: Working in MVC mode is the recommended way to work in Sitefinity CMS, especially for new projects. Development process is optimized and modification of your website functionality and appearance – quick and easy.
Generate MVC page templates from layout files
Once Sitefinity CMS detects there is a new .cshtml layout file in the respective project folder, for example, ~/ResourcePackages/YourPackageName/Mvc/Views/Layouts , upon application restart, it automatically generates a new page template, based on the layout file. At a later point in time, you can modify the page template to add grid and layout widgets.
If you have a package that includes multiple layout files, corresponding page templates are automatically created for each layout file in Sitefinity CMS under Design > Page templates.
If you delete the generated page template, it is not generated again, unless you delete and then re-add the layout file while you have the Sitefinity CMS instance up and running as a process. Another option is to manually create a pure MVC page template in Sitefinity CMS that follows the naming convention. For example, if you have a ~/MVC/Views/Layouts/MyMvcLayout.chtml file, the Developer name of the template must be MyMvcLayout. If the file is inside a package named MyPackage, ~/ResourcePackages/YourPackageName/MVC/Views/Layouts/MyMvcLayout.chtml the Developer name of the template must be MyPackage.MyMvcLayout.
If you delete the layout file, the generated page template continues to exist, but is not based on anything. Later, if you add a layout file that matches the naming convention for that template, additional template is not generated and the previous template uses this layout again.
