"Code" Portlet

This portlet displays the result of ASP.NET MVC 3 Razor code execution. The program code is added to the portlet settings.

To work with the "Code" portlet, you must have the respective access permissions, assigned by the system administrator in Administration – Users – Access Settings – Global Access Settings – Portal – Allow to use the "Code" portlet. Users, who have the permissions, will be able to add this portlet and work with it.

For example, add the list of document approval tasks, the user has to complete.

To do so, write the program code (fig. 3) in the portlet settings. The portlet will display the results of the code execution (fig. 1).

Each line contains information on one approval. The first part of the line («Approve Document») is the task name, the second part is the document name. The line itself is a link to the approval task page.

Custom Portlet Settings

Each portlet has general settings, configured by the system administrator. Users can change the custom portlet settings, when configuring the main page (fig. 2).

Note, that the Razor language combines C# and HTML, and allows working with the system objects and shape the data with HTML. To learn about the language, see ASP.NET MVC 3 Razor.
