Input Text
Use the Text property to obtain or set the password entered in the editor.
To manage the cursor position and text selection, use the CursorPosition and SelectionStart/SelectionLength properties.
The Keyboard property specifies the type of the keyboard used to edit text in the editor. The ReturnType property allows you to change the appearance of the return button on the keyboard. When a user taps this button, the Completed event occurs.
Use the following properties to change the input text appearance and alignment:

Gets or sets the horizontal alignment of text entered in the editor. |
You can also use the CursorColor property to customize the color of the input cursor.
Label
A label is the editor’s input prompt string (LabelText). Editors display this string inside the edit box (when the editor is empty and not focused) or at the top of the editor.
To pin the label to the top edge of the editor box, set the IsLabelFloating property to false.
To customize the label’s appearance settings, use the following properties:

A placeholder (PlaceholderText) is the input prompt string displayed within the text box when the editor is empty.
To specify the placeholder text color, use the PlaceholderColor property.
Help Text and Error Message
You can display the following labels:
- HelpText - additional guidance about the password input displayed under the editor box.
- ErrorText - an error message that can indicate an incorrect password.
This text is displayed instead of help text below the editor box when an error is detected (HasError is true).
The BottomTextTopIndent property specifies the indent between the editor’s bottom border and help or error text.
The ReserveBottomTextLine property allows you to reserve space under the editor box to show one line of text when required (for example, to show an error message when an incorrect password is identified).
To specify the color and font attributes for the help and error text, use the following properties:
Property | Description |
---|---|
Specify the help text color for different states of the text editor. | |
Specify the error message text color. | |
BottomTextFontSize | Configure the font settings. |
Autofill
If the editor’s AutofillContentType property is set to Password, the user can automatically fill the editor with an appropriate password. Note that the device should have an enabled autofill service that contains the required values (names, dates, passwords, and so on).
Icons
The password editor can display icons within its box.
- Show/hide password icon - toggles the visibility of characters entered in the editor.
- Clear icon - removes text entered in the editor.
