The save contact task is used to enable a user to save a contact to the phone’s contact list. The SaveContactTask
class contains 26 string properties such as FirstName
, Company
, and Website
, which allow you to pass detailed information to the built-in Contacts app.
When the user finishes saving the contact, cancels out of the task, or an error occurs, the task’s Completed
event is raised.
The sample for the SaveContactTask
consists of the SaveContactTaskView
page and the SaveContactTaskViewModel
class.
The SaveContactTask
should be defined as a field in your class, like so:
readonly SaveContactTask saveContactTask = new SaveContactTask();
Subscribe to the SaveContactTask.Completed
event within your class constructor, as shown:
saveContactTask.Completed
+= new EventHandler<SaveContactResult>(HandleCompleted);
The sample page allows the population of just some of the SaveContactTask
properties (see Figure 14.25).
When the application bar button is tapped, the Show
method of the SaveContactTask
launches the built-in Contacts application.
When the task returns, the Completed
event handler receives a SaveContactResult
object that allows you to determine whether the task completed successfully. See the following excerpt:
void HandleTaskCompleted(object sender, SaveContactResult e)
{
if (e.Error != null)
{
MessageService.ShowError("Unable to save contact.");
return;
}
if (e.TaskResult == TaskResult.OK)
{
MessageService.ShowMessage("Contact saved.");
}
}
