Entry works with EventToCommandBehavior Custom Renderner does not

AgredoAgredo USMember ✭✭

I created a custom renderer for an Entry to disable borders in XAML (BorderVisibility).

                    <UserControl:TextBox BorderVisibility="False"
                                     Placeholder="{Binding PasswordEntryPlaceholderText}"
                                     Text="{Binding PasswordEntryText}"
                            <behaviorsPack:EventToCommandBehavior Command="{Binding LogInButtonCommand}" EventName="Completed"/>

This custom control does not work with EventToCommandBehavior. Replacing "UserControl:TextBox" with "Entry" and deleting "BorderVisibility="False"" works perfectly.
What and where I need to modify my custom renderer?

Here is more code:
[assembly: XamlCompilation(XamlCompilationOptions.Compile)]
namespace Retailer.CustomControl
public class TextBox : Entry
public static readonly BindableProperty BorderVisibilityProperty = BindableProperty.Create("BorderVisibility", typeof(bool), typeof(TextBox), false, BindingMode.TwoWay);

    public bool BorderVisibility
            return (bool)GetValue(BorderVisibilityProperty);
            SetValue(BorderVisibilityProperty, value);

    public new event EventHandler Completed;

    public void SendComplete()
        Completed?.Invoke(this, EventArgs.Empty);


I have renderer for iOS, Android and UWP

Thanks in advance,

    From the code you posted, we couldn't reproduce this question.What's the code of EventToCommandBehavior and the LogInButtonCommand?

    Could you please post more code snippet about this question?

    If it is convenient for you, could you please post a basic demo so that we can test on our side?
