Hi Emil,
Thanks for contacting Syncfusion Support.
Query 1: Frame is applied by default with Grid in DataTemplate.
Since it is rendered from native. By default,
On Android: It is rendered with frame.
On UWP: It is not rendered with frame.
Query 2: Frame is not applied with margin.
This is a framework level bug. We have reported this problem to Xamarin. As of now we have resolved it in the sample level by customizing template based on platform.
Query 3: Need to hide the column scroll bar visibility in UWP.
We have achieved your requirement in sample level using custom Kanban renderer.
Please find the demo sample from the below location.
Regards,
Sridharan
