With a button i send an email , before i send it want to check if the Textinputlayout's are empty .

All fields must be filled before sending the email.

With a normal Entry i check it like this . 
But Textinputlayout not working , cannot be converted to string. What do i change

void OnVerzendButtonClicked(object sender, EventArgs args)
            if ( !string.IsNullOrWhiteSpace(EmailBody.Text) && !string.IsNullOrWhiteSpace(Voornaam.Text) && !string.IsNullOrWhiteSpace(Achternaam.Text))
                EmailSubject.Text = Voornaam.Text + " " + Achternaam.Text;
                var EmailTask = CrossMessaging.Current.EmailMessenger;

                if (EmailTask.CanSendEmail)
                    EmailTask.SendEmail("........@gmail.com", EmailSubject.Text, EmailBody.Text);

               _ = DisplayAlert("Error", "There are some empty fields !", "OK");


And in Xaml

<inputLayout:SfTextInputLayout x:Name="Voornaam" HelperText="Voornaam" AbsoluteLayout.LayoutBounds=".10,.82,.35,.55" AbsoluteLayout.LayoutFlags="All">
                        <Entry />
                    <inputLayout:SfTextInputLayout x:Name="Achternaam" HelperText="Achternaam" AbsoluteLayout.LayoutBounds=".88,.82,.48,.55" AbsoluteLayout.LayoutFlags="All">
                        <Entry />

                    <Entry x:Name="EmailSubject" Placeholder="Onderwerp Email" BackgroundColor="White" TextColor="Black"  FontSize="Small" AbsoluteLayout.LayoutBounds="30,330,300,35" AbsoluteLayout.LayoutFlags="None"/>

                    <Editor x:Name="EmailBody" Placeholder="Bericht" BackgroundColor="White" TextColor="Black"  FontSize="Small" AbsoluteLayout.LayoutBounds="30,350,300,15" AbsoluteLayout.LayoutFlags="None" />

Hi Boris, 
Greetings from Syncfusion. 
To get the entry text which is placed inside text input layout, we can use InputView property as shown in the below code snippet. 
string text = (Voornaam.InputView as Entry).Text; 
Also, you can refer the documentation link to know more information on text input layout.
