  • Can you add a link to the Datepicker library and also be more specific about which browser version you tried? IE behavior can vary pretty dramatically even just going back to 8. Have you tried on other browsers? – Adrian Larson Feb 5 '16 at 16:39
  • Thank-you for sharing comments. I tried this chrome and IE11. Issue was happened in both browsers. Please elaborate which link I needs to add for data picker library, – Venkata Raja Feb 6 '16 at 12:35
