Accessibility value on Xamarin

An accessibility value helps users of assistive technologies to understand the value of elements on the screen. A slider should indicate the currently selected value, and ideally also it's minimum and maximum value. The screen reader announces the value of elements as it reads the screen. It is important to assign correct values to elements to avoid misunderstanding.

Xamarin Forms elements such as Button and Entry automatically include an accessibility value. When you make custom elements you have to set these properties yourself.

However, there is no dedicated property to set an accessibility value. You can embed the value inside the label by using MultiBinding inside the AutomationProperties.Name property.

        <MultiBinding StringFormat="{}{0}, {1}">
            <Binding Source="The value is: " />
            <Binding Source="{BindingValue}" />
