Sample: Howto display a list of calendar items in ListView using EWS

Here is a helpful sample of using EWS to get a list of calendar items and displaying them in a ListView.

You should be able to use this with he sample I published prior on creating a CalendarView:

Sample: Using Calendar Views with EWS.

The sample below calls GetFileAttachmentsCount, which I have blogge here:

OK, on to the sample:

    //-------------------------------------------------------------------------------------------

    // RequestAndDisplayCalendarFullView

    // Populates the ListView with a list of appointments defined in the calendar view.

    //-------------------------------------------------------------------------------------------

    public static void RequestAndDisplayCalendarFullView(

                ExchangeServiceBinding binding,

                CalendarViewType calendarView,

                ref ListView lvView)

    {

        FindItemType findItemRequest = new FindItemType();

        findItemRequest.ParentFolderIds = new DistinguishedFolderIdType[] { new DistinguishedFolderIdType() };

        ((DistinguishedFolderIdType)findItemRequest.ParentFolderIds[0]).Id =

            DistinguishedFolderIdNameType.calendar;

        findItemRequest.Traversal = ItemQueryTraversalType.Shallow;

        ItemResponseShapeType itemShapeDefinition = new ItemResponseShapeType();

        itemShapeDefinition.BaseShape = DefaultShapeNamesType.AllProperties;

        findItemRequest.Item = calendarView;

        findItemRequest.ItemShape = itemShapeDefinition;

        // Do the EWS Call.

        FindItemResponseType findItemResponse = binding.FindItem(findItemRequest);

        if (findItemResponse.ResponseMessages.Items[0].ResponseClass !=

                ResponseClassType.Success)

        {

            // Indicate we have a problem

            throw new Exception(String.Format(

                "Unable to get calendar view\r\n{0}\r\n{1}",

                findItemResponse.ResponseMessages.Items[0].ResponseCode,

                findItemResponse.ResponseMessages.Items[0].MessageText));

        }

        FindItemResponseMessageType findItemResponseMessage =

            (FindItemResponseMessageType)findItemResponse.ResponseMessages.Items[0];

        ArrayOfRealItemsType findItemResponseItems =

            (ArrayOfRealItemsType)findItemResponseMessage.RootFolder.Item;

        ListViewItem lvItem = null;

        int iAttachmentCount = 0;

        lvView.Clear();

        lvView.View = View.Details; // Set the view to show details.

        lvView.GridLines = true; // Display grid lines.

        lvView.Columns.Add("Subject", 200, HorizontalAlignment.Left);

        lvView.Columns.Add("Recurring", 80, HorizontalAlignment.Left);

        lvView.Columns.Add("Start", 120, HorizontalAlignment.Left);

        lvView.Columns.Add("End", 120, HorizontalAlignment.Left);

        lvView.Columns.Add("Organizer", 80, HorizontalAlignment.Left);

        lvView.Columns.Add("#@", 40, HorizontalAlignment.Left);

        lvView.Columns.Add("Meeting", 80, HorizontalAlignment.Left);

        for (int x = 0;

            x < findItemResponseMessage.RootFolder.TotalItemsInView;

            x++)

        {

            CalendarItemType currentCalendarItem =

                (CalendarItemType)findItemResponseItems.Items[x];

            Debug.WriteLine(currentCalendarItem.Subject);

            lvItem = new ListViewItem(String.Format("{0}", currentCalendarItem.Subject, 0));

            lvItem.SubItems.Add(currentCalendarItem.IsRecurring.ToString());

            lvItem.SubItems.Add(currentCalendarItem.Start.ToLocalTime().ToString());

            lvItem.SubItems.Add(currentCalendarItem.End.ToLocalTime().ToString());

            lvItem.SubItems.Add(String.Format("{0}", currentCalendarItem.Organizer.Item.Name));

            iAttachmentCount = EwsAttachments.GetFileAttachmentsCount(binding, currentCalendarItem.ItemId);

            lvItem.SubItems.Add(String.Format("{0}", iAttachmentCount.ToString()));

            lvItem.SubItems.Add(String.Format("{0}", currentCalendarItem.IsMeeting.ToString()));

            lvItem.Tag = string.Format("{0}:{1}", currentCalendarItem.ItemId.Id, currentCalendarItem.ItemId.ChangeKey);

            lvView.Items.Add(lvItem);

            lvItem = null;

        }

    }
