如何避免Xamarin Forms iOS中显示和隐藏UI控件的波动？

Question

I have layout where i am trying to hide and show 2 buttons on click of down arrow button which is in expandable list which is creating fluctuation in 2 buttons.

Tried reducing height of those 2 buttons initially and then give some height dynamically.

<Button x:Name="completebtn" IsVisible="{Binding TaskStatus}"
                                   AutomationId="btnComplete"
                                   Command="{Binding BindingContext.CompleteOptionClickedCommand,
                                    Source={x:Reference taskList}}" CommandParameter="{Binding .}"
                                   Style="{StaticResource darkBlueButton}"
                                   Text="Complete"
                                   HeightRequest="50"  
                                   WidthRequest="120"></Button>

Actual behavior is when i expand and collapse any list item the two buttons within the list item should not fluctuate until and unless i click on down arrow button.

To hide and show a View in Xamarin Forms you use the IsVisible property which accepts a boolean and is by default set to true.

You can use it like this:

<Button x:Name="MyButton"...... IsVisible="false"/>

Then In your code, you can set it back to visible, as follows:

MyButton.IsVisible=true;
