Check if Textinputlayout is empty

[Boris Oprit]

Hello,

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("[email protected]", EmailSubject.Text, EmailBody.Text);

            }

            else

            {

               _ = 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>

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

                        <Entry />

                    </inputLayout:SfTextInputLayout>

                    <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. 

 

[C#] 

string text = (Voornaam.InputView as Entry).Text; 

 

 

Also, you can refer the documentation link to know more information on text input layout.

Thanks,
