I'm currently working to make sure all of my custom code works correctly in SharePoint Foundation 2010. One of my webparts utilized the SPCalendarView and I would set the datasource to be a SPCalendarItemCollection and it would render a calendar with the events I specified in the collection. Well, this no longer works in SharePoint Foundation 2010. I was able to achieve a workaround with a little help from reflector. You'll need to create two classes:

public class MySPCalendarDataSource : Control, System.Web.UI.IDataSource
    {
        private MyCalendarSourceView _view;
        private static readonly object EventDataSourceChanged = new object();
        private SPCalendarItemCollection _data = null;

        public MySPCalendarDataSource(SPCalendarItemCollection data)
            : base()
        {
            _data = data;
        }

        event EventHandler System.Web.UI.IDataSource.DataSourceChanged
        {
            add
            {
                base.Events.AddHandler(EventDataSourceChanged, value);
            }

            remove
            {
                base.Events.RemoveHandler(EventDataSourceChanged, value);
            }
        }

        protected DataSourceView GetView(string viewName)
        {
            return this.internalGetView(viewName);
        }

        protected ICollection GetViewNames()
        {
            return new string[] { this.internalGetView(null).Name };
        }

        private MyCalendarSourceView internalGetView(string viewName)
        {
            if (this._view == null)
            {
                this._view = new MyCalendarSourceView(this, viewName, _data);
            }
            return this._view;
        }

        private void OnDataSourceChanged(EventArgs e)
        {
            EventHandler handler = (EventHandler)base.Events[EventDataSourceChanged];
            if (handler != null)
            {
                handler(this, e);
            }
        }

        protected virtual void RaiseDataSourceChangedEvent(EventArgs e)
        {
            this.OnDataSourceChanged(e);
        }

        DataSourceView System.Web.UI.IDataSource.GetView(string viewName)
        {
            return this.GetView(viewName);
        }

        ICollection System.Web.UI.IDataSource.GetViewNames()
        {
            return this.GetViewNames();
        }        
    }

public class MyCalendarSourceView : DataSourceView
{
	SPCalendarItemCollection _data;
	
	public MyCalendarSourceView(System.Web.UI.IDataSource ds, string viewName, SPCalendarItemCollection data) : base(ds, viewName)
	{
		_data = data;
	}

	protected override System.Collections.IEnumerable ExecuteSelect(DataSourceSelectArguments arguments)
	{
		return _data;
	}
}

And where in SharePoint 2007 you could do this:

SPCalendarItemCollection items = GetCalendarItems();
SPCalendarView calView = new SPCalendarView();
calView.DataSource = items;
calView.DataBind();

You now have to do this:

SPCalendarItemCollection items = GetCalendarItems();
SPCalendarView calView = new SPCalendarView();
calView.EnableV4Rendering = false;
calView.DataSource = new MySPCalendarDataSource(items);
calView.DataBind();

Also, please note that for this to work, we do need to disable the V4 ajax rendering.

Can this custom data source be used for. Written by This e-mail address is being protected from spam bots, you need JavaScript enabled to view it on 2010-09-23 05:00:39 can this custom data source be used to render more than just the link to the list item when the calander view is rendered?

Written by Steve on 2010-09-23 06:03:58 Well in the monthly view you only get the SPCalendarItem.Title displayed. In the weekly and daily views, it will display whatever text you put into the SPCalendarItem.Description property in addition to the Title.
