Switch To Outlook Calendar using VSTO

问题

I have a CustomTaskPane that I have added to Microsoft Outlook 2013. This pane includes a WPF Calendar control that when double clicked I would like it to switch from the current Outlook view (Mail) to the Calendar view and go to the date selected in the control.

Here is the code I am using:

private void TopCalendar_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
    CalendarView calView = null;
    Explorer explorer;
    DateTime goToDate = (TopCalendar.SelectedDate.HasValue) ? TopCalendar.SelectedDate.Value : DateTime.Today;

    explorer = Globals.ThisAddIn.Application.ActiveExplorer();
    Views views = Globals.ThisAddIn.Application.GetNamespace("MAPI").GetDefaultFolder(OlDefaultFolders.olFolderCalendar).Views;

    foreach(View v in views)
        if (v.Name == "Calendar")
        {
            calView = (CalendarView)v;
            break;
        }

    calView.CalendarViewMode = OlCalendarViewMode.olCalendarViewMonth;
    calView.GoToDate(goToDate);
    explorer.CurrentView = calView;
}

However, when I double-click on a date the code is called (verified with breakpoint) but seems to have no effect on Outlook at all. Any suggestions?

Make sure you call Apply() to make the view the current view for the Folder. You also need to assign the CurrentFolder to the Calendar.

calView.Apply(); // applies the view
explorer.CurrentFolder = Globals.ThisAddIn.Application.GetNamespace("MAPI").GetDefaultFolder(OlDefaultFolders.olFolderCalendar); // changes current folder
