Voting in polls is available not only for the community members but community site visitors can also take part in voting; this can be useful to get feedback even from people who are not members. 2.25.1 Adding a Poll Before a poll can be used, first it has to be created and added to the community. To add a poll, first an object of Poll type has to be created, and then it has to be committed in the database using the AddPoll method of the PollHandler class. Import Necessary Namespaces First, import the necessary namespaces that will be used to add a poll. The namespaces StarSuite.Core, StarCommunity.Core and StarCommunity.Modules.Poll are described by clicking on their respective names. Make sure you add the assembly as a reference, mentioned in section 1.1.1. using StarSuite.Core; using StarCommunity.Core; using StarCommunity.Core.Modules; using StarCommunity.Core.Modules.Security; using StarCommunity.Modules.Poll; © EPiServer AB
Tutorials | 101 Add a Poll In this example, we will add a test poll to the community. The poll will contain three choices, and will not be assigned to any site. First, an object of the Poll type is created, and then it has to be committed to the database using the AddPoll method of the PollHandler class. // Poll text string text = "Best hamburgers are made by:"; // Poll author – current user will be the author IUser currentUser = (IUser)StarCommunitySystem. CurrentContext.DefaultSecurity.CurrentUser; IAuthor author = new UserAuthor(currentUser); // Poll activity bool isActive = true; // Poll site – when set to null, the poll is not assigned ISite site = null; // Start and end date when voting can occur DateTime start = new DateTime(2007,3,1); DateTime end = new DateTime(2007,4,1); // Create a poll object Poll poll = new Poll(text, author, isActive, site, start, end); // Create two choices – when creating Choice set text and order Choice choice1 = new Choice("McDonald’s", 0); Choice choice2 = new Choice("Burger King", 1); // Add choices to the poll poll.Choices.Add( choice1 ); poll.Choices.Add( choice2 ); // Commit poll object in database; // after this operation poll’s ID property is set poll = PollHandler.AddPoll(poll); 2.25.2 Removing a Poll When a poll is no longer needed, it can be removed from the community database. To remove a poll, we need to get the poll information from the database (get the Poll object). Then, the poll can be deleted using the RemovePoll method of the PollHandler class. © EPiServer AB
