Hmm it still appears to not be working for me

I added the following to Sandbox and the clear button still appears to not be functional:

    <VerticalStackLayout>

            <Entry
                HorizontalOptions="Center"
                WidthRequest="300"
                ClearButtonVisibility="WhileEditing"
                BackgroundColor="LightGray"
                Text="ClearButtonVisibility" />
            
    </VerticalStackLayout>

Am I missing something?

Could you try it again?

<VerticalStackLayout>
      <Entry
          HorizontalOptions="Center"
          WidthRequest="300"
          ClearButtonVisibility="WhileEditing"
          BackgroundColor="LightGray"
          Text="ClearButtonVisibility" />
      <Entry
          HorizontalOptions="Center"
          WidthRequest="300"
          FlowDirection="RightToLeft"
          ClearButtonVisibility="WhileEditing"
          BackgroundColor="LightGray"
          Text="ClearButtonVisibility" />
      <Entry
          HorizontalOptions="Center"
          ClearButtonVisibility="WhileEditing"
          BackgroundColor="LightGray"
          Text="ClearButtonVisibility" />
      <Entry
          HorizontalOptions="Center"
          ClearButtonVisibility="WhileEditing" 
          FlowDirection="RightToLeft"
          BackgroundColor="LightGray"
          Text="ClearButtonVisibility" />
  </VerticalStackLayout>

you can set the Text for "" or empty value ,You will see the phenomenon of the bug, the delete button will not show

[hartez]

The button does not disappear when the text length goes to zero during editing, and the button does not appear if the text length was zero when the Entry gained focus.

[hartez]

Okay, fixed it so the clear button status updates when the text changes. The button now appears when you add text to a blank entry, and disappears when the entry no longer has text.

@hartez what is RawX vs GetX?
