TextBox
Last Updated On 2021-07-16
Version 6MinSDK 7Tutorial Video
A box for the user to enter text. The initial or user-entered text value is in the Text
property. If blank, the Hint
property, which appears as faint text in the box, can provide the user with guidance as to what to type.
The MultiLine
property determines if the text can havemore than one line. For a single line text box, the keyboard will closeautomatically 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 acceptnumeric 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.
