According to http://www.telerik.com/blogs/ui-for-uwp-is-officially-here-bringing-datagrid-beta, the official release of DataGrid (due Q2 2016) was supposed to bring a responsive control, making it suitable for use on a phone.
However, I'm not getting that experience. I'm not sure how Telerik envision DataGrid being responsive but, when I use it on a phone, I have to scroll from side-to-side in order to see all of the data on a single row.
I don't know whether or not responsiveness made it into the control. The documentation doesn't seem to make any reference to getting the control to adapt to different screen sizes.
I'm keen to use this control on a phone but I'm struggling to find a way of getting it to look good.
