What is the best way once a visitor has logged on to the web site to have them fill out a custom form but associate that response with that user? I'd like to have users fill out surveys once they log on the my web site.

Thanks,
Matt

Hello Matt,

This can be done with the forms control. You may need to modify the log in widget(you can get its template from Sitefinity SDK) to redirect to a page where the survey is placed. By default Forms get the user ID, but not the user name. You can follow this forum thread if you want to search users by the ID and apply this to suit your needs. Also when you submit a response this created FormEntry object which has a property - UserId. This is the ID of the user submitted the form. To get the response of a form you can use
public IEnumerable GetFormEntries(Type entryType, string filter, string orderBy, int skip, int take, ref int? count)

Below is a sample code that shows getting form results filtered by user ID

var formsManager = FormsManager.GetManager();

string entryTypeName = String.Format("0.1", "Telerik.Sitefinity.DynamicTypes.Model", "sf_yourformname");

var itemType = formsManager.GetEntryType(entryTypeName);

var userID = SecurityManager.GetCurrentUserId();

var fakeID = new Guid("4B15FA4B-6C36-4CE5-A56D-9FDFB6E541DF");

var filter = "UserId ==" + fakeID + "";

int? totalCount = 0;

IEnumerable items = null;

try

items = formsManager.GetFormEntries(itemType, filter, "Title ASC", 0, 100, ref totalCount);

catch

When you get the ID you can use more logic to list the users or populate a widget with their names corresponding to the ID`s.

To take the username when submitting the form. You will have to inherit FormsControl and create a textfield that will be hidden from the user filling the form. When the form is submitted OnBeforeFormSave is called which walks trough all form fields and then save their values to be sent to the forms module. When OnBeforeFormSave is executed you must fill the value of the hidden textfield with the username by using GetUserDisplayName which gets the username by the supplied ID.
