I have created calendar list using visual studio 2013 with two views in List Instance. Now i want to create some calendar overlays using same views i have created in list instance.
Please help me to create calendar overlay using visual studio list instance.
I can achieve through SharePoint UI but i need solution to achieve the same using VS list instance.
What does OP mean by instance? List definition in XML? In that case maybe not, but there is code for that which I have successfully used many a time. Just stick that in an event receiver and you're good to go:
public static void AddCalendarOverlay(SPList targetList, string viewName, SPList overlayList, string overlayListView, string overlayName, string overlayDescription, CalendarOverlayColor color, bool alwaysShow, bool clearExisting)
{
bool sharePoint = overlayList != null;
SPView overlayView = overlayList.DefaultView;
if (!string.IsNullOrEmpty(overlayListView))
{
if (overlayList.Views[overlayListView] != null)
{
overlayView = overlayList.Views[overlayListView];
}
}
string linkUrl = overlayView.ServerRelativeUrl;
SPView targetView = targetList.DefaultView;
if (!string.IsNullOrEmpty(viewName))
{
if (targetList.Views[viewName] != null)
{
targetView = targetList.Views[viewName];
}
}
XmlDocument xml = new XmlDocument();
XmlElement aggregationElement = null;
int count = 0;
if (string.IsNullOrEmpty(targetView.CalendarSettings) || clearExisting)
{
xml.AppendChild(xml.CreateElement("AggregationCalendars"));
aggregationElement = xml.CreateElement("AggregationCalendar");
xml.DocumentElement.AppendChild(aggregationElement);
}
else
{
xml.LoadXml(targetView.CalendarSettings);
XmlNodeList calendars = xml.SelectNodes("/AggregationCalendars/AggregationCalendar");
if (calendars != null)
count = calendars.Count;
aggregationElement = xml.SelectSingleNode(string.Format("/AggregationCalendars/AggregationCalendar[@CalendarUrl='{0}']", linkUrl)) as XmlElement;
if (aggregationElement == null)
{
if (count >= 10)
throw new SPException(string.Format("10 calendar ovarlays already exist for the calendar {0}.", targetList.RootFolder.ServerRelativeUrl));
aggregationElement = xml.CreateElement("AggregationCalendar");
xml.DocumentElement.AppendChild(aggregationElement);
}
}
if (!aggregationElement.HasAttribute("Id"))
aggregationElement.SetAttribute("Id", Guid.NewGuid().ToString("B", CultureInfo.InvariantCulture));
aggregationElement.SetAttribute("Type", sharePoint ? "SharePoint" : "Exchange");
aggregationElement.SetAttribute("Name", !string.IsNullOrEmpty(overlayName) ? overlayName : (overlayList == null ? "" : overlayList.Title));
aggregationElement.SetAttribute("Description", !string.IsNullOrEmpty(overlayDescription) ? overlayDescription : (overlayList == null ? "" : overlayList.Description));
aggregationElement.SetAttribute("Color", ((int)color).ToString());
aggregationElement.SetAttribute("AlwaysShow", alwaysShow.ToString());
aggregationElement.SetAttribute("CalendarUrl", linkUrl);
XmlElement settingsElement = aggregationElement.SelectSingleNode("./Settings") as XmlElement;
if (settingsElement == null)
{
settingsElement = xml.CreateElement("Settings");
aggregationElement.AppendChild(settingsElement);
}
if (sharePoint)
{
settingsElement.SetAttribute("WebUrl", overlayList.ParentWeb.Site.MakeFullUrl(overlayList.ParentWebUrl));
settingsElement.SetAttribute("ListId", overlayList.ID.ToString("B", CultureInfo.InvariantCulture));
settingsElement.SetAttribute("ViewId", overlayView.ID.ToString("B", CultureInfo.InvariantCulture));
settingsElement.SetAttribute("ListFormUrl", overlayList.Forms[PAGETYPE.PAGE_DISPLAYFORM].ServerRelativeUrl);
}
targetView.CalendarSettings = xml.OuterXml;
targetView.Update();
}
Most of the code is self-explanatory, but if you need any clarification I will be happy to help.
