Timeslider control should be instrumented in ArcGIS Runtime SDK for Windows Phone.

Idea created by atsuhito_nakanoesrij-esridist Employee on Feb 15, 2012
    Currently "Timeslider" control is not instrumented in ArcGIS SDK Runtime for Windows Phone.
    So users could not help but use simple slider or other control to express time layer, and that is not fuss-free.

    If there were Timeslider Control, it would save someone a lot of effort.

    Therefore I think that "Timeslider" control is needed for Windows Phone.
