  • Overview

    The Telerik UI for Blazor TextArea component is the control to use when you expect the user to type multiline text for long inputs like notes, comments or descriptions. It shares many properties with the other text-input components in the suite like auto resizing, floating labels and a number of events.

    Telerik UI for Blazor TextArea Overview
  • Auto Sizing

    The AutoSize property will force the component to resize itself during keyboard input so that it takes just enough space to contain the text content but not any more than that.

  • Floating Labels

    Floating labels are important to creating modern UIs and are a part of all of our text input components. When enabled, the TextArea’s placeholder will float upwards and stop above the control for a sleek visual effect. If you don’t need this feature, you can always disable it and use a standard label attached to the TextArea. See how to implement a floating label on our demo page.

  • Events

    The two standard OnChange and ValueChanged are available with the TextArea Component:

    • OnChange is fired whenever the user confirms the new value – by pressing Enter or when the component loses focus. This event can be used with two-way binding
    • ValueChanged is fired on every keystroke. This event cannot be used simultaneously with two-way binding
    • OnBlur - an event which is triggered when it loses focus

  • TabIndex

    The Blazor TextArea component, just like all other Telerik UI for Blazor input components, supports keyboard navigation to switch between components thanks to the HTML TabIndex property. Pressing Tab will normally focus the next available input component, the same way your users are accustomed to when standard HTML inputs are used. Having the TabIndex setting lets you customize that order.
  • Theming

    The Telerik UI for Blazor TextArea has several built-in themes such as Default (our own styling), Material (based on the Material Design guidelines) and Bootstrap (which looks like the Bootstrap styling to integrate better). You can easily customize any of out-of-the-box themes with a few lines of CSS, or create new theme to match your colors and branding by using the Telerik SASS ThemeBuilder application.
