The initial or user-entered text value in a text box component is in the Text property. If Text is blank, you can use the Hint property to provide the user with a suggestion of what to type. The Hint appears as faint text in the box.
The MultiLine property determines if the text can have more than one line. For a single line text box, the keyboard will close automatically when the user presses the Done key. To close the keyboard for multiline text boxes, the app should use the HideKeyboard method or rely on the user to press the Back key.
The NumbersOnly property restricts the keyboard to accept numeric input only.
Other properties affect the appearance of the text box ( TextAlignment , BackgroundColor , etc.) and whether it can be used ( Enabled ).
Text boxes are usually used with the Button component, with the user clicking on the button when text entry is complete.
If the text entered by the user should not be displayed, use PasswordTextBox instead.
Hide the keyboard. Only multiline text boxes need this. Single line text boxes close the keyboard when the users presses the Done key.

Text that should appear faintly in the input box to provide a hint as to what the user should enter. This can only be seen if the Text property is empty.
If true, then this text box accepts multiple lines of input, which are entered using the return key. For single line text boxes there is a Done key instead of a return key, and pressing Done hides the keyboard. The app should call the HideKeyboard method to hide the keyboard for a mutiline text box.
If true, then this text box accepts only numbers as keyboard input. Numbers can include a decimal point and an optional leading minus sign. This applies to keyboard input only. Even if NumbersOnly is true, you can use [set Text to] to enter any text at all.
