Control is created using Dispatcher is not visible initially in Xamarin.Forms.UWP
We have created the control using Dispatcher in native UWP. We have added this control as item in ListView using ItemTemplate. When run the application,control is not visible on loading time. But control is visible after resize the window.
We have reproduced this problem in simple sample, please find the attached sample.Also,if you create any Shapes(like Rectangle) instead of control in dispatcher, then it visible on loading time.
** Steps to Reproduce **
1. Run the attached sample.
2. control will not visible initially.
3. Resize the window the control will be visible.
Note: problem reproduced only when add control in ListView.
See the answer in https://bugzilla.xamarin.com/show_bug.cgi?id=38092, which I just tested and displays the control.
Provided workaround solution is not possible in custom control which is created in native UWP. Since we didn't refer the xamarin assemblies in native UWP. We can visible the shapes on loading time, only problem happened for control when using in dispatcher. Could you fix this issue ?
