TextBox
This topic describes the options and limitations available when using a TextBox component.
Content settings
- Text
- This setting displays any text that is entered in the field. If you
provide text as part of the component specification, that text displays by default and
overrides any Placeholder
text that might exist.
Users can override any text you might have provided, unless you create the component as a read-only field. Even if they do so, your default text remains as part of the component configuration, though it does not display in runtime.
Note: Keep in mind that this field can only be one line high. Any text that extends beyond the end of the field can only be read by moving the cursor beyond the edge of the field.Depending on how you intend to use this component, you can:
- Provide text for informational, read-only purposes.
- Use the field for user input that can be further processed.
- Employ another component to populate the field with text from a data service.
- And so on...
- Label
- This setting determines what text is to display as the label for the
text box, if a label is used. Note: The setting to either display or hide the label is made on the Style tab.
- Placeholder
- This setting allows you to provide text to be used as a placeholder,
typically as a prompt for user input. The text displays in a gray font. As soon as the
user enters any text into the field, the placeholder text disappears.
Any text you use in the Text setting overrides and hides any Placeholder text.
