Is it possible to use the BusyIndicator without the Content Property?

[Trevor]

I have a bunch of ActivityIndicators in my application already, but the native ActivityIndicator doesn't scale well on iOS. Is it possible to just use the BusyIndicator without content? I don't want to have to refactor my views if I do not have to.

Hello Trevor,

To achieve what you're looking for, you can position the RadBusyIndicator on top of your content. Then, within the RadBusyIndicator's content, place an element and bind its WidthRequest and HeightRequest to the page's Width and Height properties.

Pasted below is a demo I've written that will overlays the RadBusyIndicator on top the the green BoxView by toggling the IsVisible and IsBusy properties:

XAML:

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage x:Name="MyPage" xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:telerikPrimitives="clr-namespace:Telerik.XamarinForms.Primitives;assembly=Telerik.XamarinForms.Primitives"
             x:Class="TrevorDemo.Portable.StartPage">

    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition/>
            <RowDefinition Height="Auto"/>
        </Grid.RowDefinitions>

        <BoxView WidthRequest="200" HeightRequest="200" BackgroundColor="Green" HorizontalOptions="Center" VerticalOptions="Center"></BoxView>

        <telerikPrimitives:RadBusyIndicator x:Name="BusyIndicator" IsVisible="False">
            <telerikPrimitives:RadBusyIndicator.Content>
                <Grid BindingContext="{x:Reference MyPage}" HeightRequest="{Binding Height}" WidthRequest="{Binding Width}">

                </Grid>
            </telerikPrimitives:RadBusyIndicator.Content>
        </telerikPrimitives:RadBusyIndicator>

        <Button Text="Toggle BusyIndicator" Clicked="Button_OnClicked" Grid.Row="1"/>
    </Grid>

</ContentPage>

Code behind:

namespace TrevorDemo.Portable
{
    public partial class StartPage : ContentPage
    {
        public StartPage()
        {
            InitializeComponent();
        }

        private void Button_OnClicked(object sender, EventArgs e)
        {
            BusyIndicator.IsVisible = !BusyIndicator.IsVisible;
            BusyIndicator.IsBusy = !BusyIndicator.IsBusy;
        }
    }
}
