问题 I am using Xamarin.forms.Maps for showing the map in my project. The map is inside the ListView and I need to bind the coordinate positions to the map. Model Class: public class History { public double Latitude { get; set; } public double Longitude { get; set; } } Data adding part: historyList.Add(new History() { Latitude= -28.854930 ,Longitude= 151.166023 }); historyList.Add(new History() { Latitude = -28.853671, Longitude = 151.165712 }); historyList.Add(new History() { Latitude = -28

问题 There is only valueChanged Event defined for Slider control, I need to develop mousedown,mouseup and Mousemove events. When a user clicks on the slider, on the view it should display "Mouse is up", "Mouse is down". But I can't able to develop that implementation.Any code help is greatly appreciated. 回答1: There is no mouse in mobile, therefore there will not be any mouse events.

问题 Hoping you can advise as I've tried all methods to bind a picker in a Listview to my item source values using both code-behind and MVVM.

问题 I'm building a custom XAML control for a UWP app that relies heavily on a ScrollViewer with snap points. I would really like the content that is bound to the control to be virtualized, so I'm using an ItemsControl. However, when I use a VirtualizingStackPanel in the ItemsControl, and then call ChangeView() on the ScrollViewer to a specific HorizontalOffset, the animation effect when scrolling to the new offset is disabled (it just jumps directly to the offset). If I simply replace the
