Display tooltips

A .NET Multi-platform App UI (.NET MAUI) tooltip is a small rectangular popup that displays a brief description of a view's purpose, when the user rests the pointer on the view. Tooltips display automatically, typically when the user hovers the pointer over the associated view:

• On Android, tooltips are displayed when users long press the view. Tooltips remain visible for a few seconds after the long press is released.
• On iOS, to show a tooltip your app must be an iPhone or iPad app running on a Mac with Apple silicon. Providing this criteria is met, tooltips are displayed when the pointer is positioned over the view for a few seconds, and remain visible until the pointer moves away from the view. Tooltips on iOS require the use of iOS 15.0+. For more information about using iPhone and iPad apps on a Mac with Apple silicon, see Use iPhone and iPad apps on Mac with Apple silicon.
• On Mac Catalyst, tooltips are displayed when the pointer is positioned over the view for a few seconds. Tooltips remain visible until the pointer moves away from the view. Tooltips on Mac Catalyst require the use of Mac Catalyst 15.0+.
• On Windows, tooltips are displayed when the pointer hovers over the view. Tooltips remain visible for a few seconds, or until the pointer stops hovering over the view.

Tooltips are defined by setting the ToolTipProperties.Text attached property, on a view, to a string:

<Button Text="Save"
        ToolTipProperties.Text="Click to Save your data" />

The equivalent C# code is:

Button button = new Button { Text = "Save" };
ToolTipProperties.SetText(button, "Click to Save your data");

For more information about attached properties, see Attached properties.

By default, a tooltip is displayed centered above the pointer:
