  • Hi Pallam,

    >>How to I use existing custom controls in WinJS?

    As far as I know, UWP(Javascript) use the Edge render engine. which is only able to parse html contents.

    So, it is impossible to use an existing XAML Control inside a WinJS Project.

    WinJS has its own controls, which looks like quite the same as XAML Controls.Please use these WinJS Controls instead.

    You can find the playground of WinJS Controls by this link: http://try.buildwinjs.com/playground/.
