描述

This issue has been moved from a ticket on Developer Community.

I have this simple xaml in a 

<StackLayout x:Name="EntriesPanel" IsEnabled="False" >
             <Label>IDX</Label>
             <Entry x:Name="IDXEntry" IsEnabled="False" />
             <Label>Name</Label>
             <Entry x:Name="NameEntry" />
             <Label>Name2</Label>
             <Entry x:Name="NameEntry2" />
        </StackLayout>

Strangely NameEntry2 is disabled as expected (inheriting from StackLayout) but NameEntry stays enabled. I have other forms with more Entry and all of them inherit from parent StackLayout apart from the first not disabled one.

研究方向
Investigate why StackLayout.IsEnabled=false is not inherited by the first Entry child. Look at the internal property inheritance mechanism in Xamarin.Forms, specifically how IsEnabled propagates to child views. Check the method that sets IsEnabled on visual elements and ensure that all children are iterated correctly. The issue might be in the layout's child enumeration order or a bug in the property change propagation.
