Hi, first sorry for my bad english.  
I'm got trouble with this in my project. Let say i have two ContentView - A and B. And in NavigationDrawer Menu i have two item is 1 and 2.

The Item 1 will make ContentView A IsVisible and ContView B is not, Item 2 will do the opposite.

The ContentPage containt NavigationDrawer is binding ViewModel C.

But then,  ContentView A and B is binding another ViewModel. So the property IsVisible of ContentView A and B is not available on ContentPage when binding with ViewModel C.

If im not binding ViewModel for ContentView A and B it's will work fine. So how can i fix this ?

Here is my code:

<navigationdrawer:SfNavigationDrawer.ContentView>
            <Grid BackgroundColor="Transparent">
                 
                <view:ContentViewB IsVisible="{Binding ContentViewVisible,Converter={StaticResource boolToBoolConventer}}"/>
                <view1:DuyetHoaDon  IsVisible="{Binding ContentViewVisible}" />
                
            </Grid>
</navigationdrawer:SfNavigationDrawer.ContentView>
