Hello Laurensius,

Thank you for your question.

Yes, you can by using style for the text box that is part of RadInputPrompt. Here's an example:

private async void ShowPrompt()
{
    Style textBoxStyle = new System.Windows.Style(typeof(RadTextBox));
    textBoxStyle.Setters.Add(new Setter(RadTextBox.AcceptsReturnProperty, true));
    textBoxStyle.Setters.Add(new Setter(RadTextBox.MinHeightProperty, 200));

    InputPromptClosedEventArgs args = await RadInputPrompt.ShowAsync("Enter your name", inputStyle: textBoxStyle);
    MessageBox.Show("Hello, " + args.Text);
}

The AcceptsReturn property will ensure that you can use Enter to go to next line and MinHeight will ensure that initially the text box will be high enough to hint for its multiline capabilities.

I hope this information helps.

Regards,
