XAML - ProgressRing

A ProgressRing is a control that indicates an ongoing operation. The typical visual appearance is a ring-shaped "spinner" that cycles an animation as the progress continues. An important point here is that WPF projects do not support ProgressRing. So for this control, we will work on Windows Store App. The hierarchical inheritance of ProgressRing class is as follows −

ProgressRing Hierarchy

Properties

Sr.No. Property & Description
1

IsActive

Gets or sets a value that indicates whether the ProgressRing is showing progress.
2

IsActiveProperty

Identifies the IsActive dependency property.
3

TemplateSettings

Gets an object that provides calculated values that can be referenced as TemplateBinding sources when defining templates for a ProgressRing control.

Events

Sr.No. Event & Description
1

ManipulationCompleted

Occurs when a manipulation on the UIElement is complete. (Inherited from UIElement)
2

ManipulationDelta

Occurs when the input device changes position during a manipulation. (Inherited from UIElement)
3

ManipulationInertiaStarting

Occurs when the input device loses contact with the UIElement object during a manipulation and inertia begins. (Inherited from UIElement)
4

ManipulationStarted

Occurs when an input device begins a manipulation on the UIElement. (Inherited from UIElement)
5

ManipulationStarting

6

ValueChanged

Occurs when the range value changes. (Inherited from RangeBase)

Methods

Sr.No. Method & Description
1

OnManipulationCompleted

Called before the ManipulationCompleted event occurs. (Inherited from Control)
2

OnManipulationDelta

Called before the ManipulationDelta event occurs. (Inherited from Control)
3

OnManipulationInertiaStarting

Called before the ManipulationInertiaStarting event occurs. (Inherited from Control)
4

OnManipulationStarted

Called before the ManipulationStarted event occurs. (Inherited from Control)
5

OnManipulationStarting

7

OnMinimumChanged

Example

The following example shows how to use ProgressRing with ToggleSwitch. Here is the code in XAML to create and initialize a ProgressRing and a ToggleSwitch −

<Page x:Class = "ProgressRing.MainPage" 
   xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation"
   xmlns:x = "http://schemas.microsoft.com/winfx/2006/xaml" 
   xmlns:local = "using:ProgressRing" 
   xmlns:d = "http://schemas.microsoft.com/expression/blend/2008" 
   xmlns:mc = "http://schemas.openxmlformats.org/markup-compatibility/2006" 
   mc:Ignorable = "d">
	
   <Grid Background = "{ThemeResource ApplicationPageBackgroundThemeBrush}"> 
      <StackPanel Orientation = "Horizontal" Margin = "342,0,-342,0"> 
         <ProgressRing x:Name = "progress1"/> 
         <ToggleSwitch Header = "ProgressRing Example" OffContent = "Do work"
            OnContent = "Working" Toggled = "ToggleSwitch_Toggled" 
            Margin = "0,348,0,347"/> 
      </StackPanel>
   </Grid> 
	
</Page>

Given below is the implementation in C# for Toggled event −

using System; 
using System.Runtime.InteropServices.WindowsRuntime; 
using Windows.Foundation; 
using Windows.Foundation.Collections; 
using Windows.UI.Xaml; 
using Windows.UI.Xaml.Controls; 
using Windows.UI.Xaml.Controls.Primitives;
 
namespace ProgressRing { 
   public sealed partial class MainPage : Page {
      public MainPage() {
         this.InitializeComponent(); 
      } 
      private void ToggleSwitch_Toggled(object sender, RoutedEventArgs e) { 
         ToggleSwitch toggleSwitch = sender as ToggleSwitch; 
			
         if (toggleSwitch != null) { 
            if (toggleSwitch.IsOn == true) { 
               progress1.IsActive = true; 
               progress1.Visibility = Visibility.Visible; 
            } else {
               progress1.IsActive = false; 
               progress1.Visibility = Visibility.Collapsed; 
            }
         }
      }
   }
}

When you compile and execute the above code, it produces the following output −

We recommend you to execute the above example code and experiment with some other properties and events in Windows App.
