Q:

Customize Xamarin.Forms.Datepicker to pick and visualize multiple Dates

i'm kinda new to the whole wpf/xamarin UI thing and want to start my first mobile app.
So, like the title contains already the topic of this question, i would like to use the standard Xamarin.Forms Datepicker to let the user pick multiple Dates.
I guess it will be pretty easy to submit on the Event for picking a date and put this into an array for the selected Dates.
But how can i visualize all the selected Dates in the Datepicker Dialog? Is there any possability to do this with this Control?
Thanks :)

A:

For your requirement, you could use Calendar. The SfCalendar plugin provide the MultiSelection SelectionMode to do that. 
 <syncfusion:SfCalendar
            x:Name="calendar"
            SelectionChanged="calendar_SelectionChanged"
            SelectionMode="MultiSelection" />

If you want to get all the list of select dates, you could do that in calendar_SelectionChanged event.
 private void calendar_SelectionChanged(object sender, Syncfusion.SfCalendar.XForms.SelectionChangedEventArgs e)
    {
        var dateAdded = e.DateAdded;
        var dateRemoved = e.DateRemoved;

        if (dateRemoved != null)
        {
            list = dateAdded.Except(dateRemoved).ToList();
        }
        else
        {
            list = dateAdded.ToList();
        }         

    }
