Use Fluent UI controls

Creating apps that look great in Microsoft Teams will be easier with our new components. Built on the Fluent UI framework, the new components will look great with Teams styles and will automatically adjust to the Teams default theme. The new controls are Button, Check box, Combo box, Date picker, Label, Radio group, Rating, Slider, Text box, and Toggle.

Let's take a look at each Fluent UI control and its most useful properties. For a complete list of controls and properties in Power Apps, go to Controls and properties in Power Apps.

Button

A control that the user can select to interact with the app.

Button control

Description

Configure the OnSelect property of a Button control to run one or more formulas when the user selects the control.

Key properties

ButtonType – The style of button to show, Standard, or Primary. Default value: Standard.

OnSelect – How the app responds when the user selects a control.

Text – Text that appears on a control or that the user enters into a control.

Check box

A control that the user can select or clear to set its value to true or false.

Check box control

Description

The user can specify a Boolean value by using this familiar control, which has been widely used in the user interface.

Key properties

Box side – The side of the control on which the check box is displayed.

Label – Text that appears on a control.

Checked – Whether the control is checked or not.

Combo box

A control that allows users to make selections from provided choices. Supports search and multiple selections.

Combo box control

Description

A Combo box control allows a user to search for items to select. The search is done server-side on the SearchField property, so performance isn't affected by large data sources.

Single-select or multiple-select mode is configured via the SelectMultiple property.

Key properties

Items – The source of data from which selections can be made.

DefaultSelectedItems – The items that are initially selected before the user interacts with the control.

SelectMultiple – Whether the user can select a single item or multiple items.

IsSearchable – Whether the user can search for items before selecting.

Date picker

A control that the user can select to specify a date.

Date picker control

Description

If you add a Date picker control instead of a text input control, you help ensure that the user specifies a date in the correct format.

Key properties

Value – The date currently selected in a date control. This date is represented in local time.

Format – The text format in which the control shows the date and the user specifies the date. You can set this property to ShortDate (default) or LongDate to format dates based on the Language property of this control. You can also set this property to an expression, such as yyyy/mm/dd, if you want the same format independent of the language. For example:

  • The control shows 12/31/2017 if the user selects the last day of 2017, the Format property is set to ShortDate, and the Language property is set to en-us.

  • The control shows dimanche 31 December 2017 if the user selects the last day of 2017, the Format property is set to LongDate, and the Language property is set to fr-fr.

Label

A box that shows data such as text, numbers, dates, or currency.

Label control

Description

A label shows data that you specify as a literal string of text or as a formula that evaluates to a string of text. Labels often appear outside of any other control (such as a banner that identifies a screen), as a label that identifies another control (such as a rating or audio control), or in a gallery to show a specific type of information about an item.

Key properties
