CharmFlyout - Another Charming Custom Control

My goal is to make adding Settings Charm Flyouts to a C# Metro application as easy as possible. To that end, I created a custom control called CharmFlyout.

• CharmFlyout – Supporting sub-flyouts

Install CharmFlyout from NuGet.org and add to your existing Metro application:

1. Install the NuGet Package Manager if you have not already.
2. Open your Metro application in Visual Studio
3. Select Manage NuGet Packages from the Project menu.
4. Click Online. Search for CharmFlyout. Click Install.

If you have a single page application with a MainPage.xaml, then edit MainPage.xaml to:

1. Add the using:CharmFlyoutLibrary.
2. Add the CharmFlyout custom control.
3. Add content to the CharmFlyout. In the example below, the content is a StackPanel.

<Page
   x:Class="CharmDemoApp.MainPage"
   IsTabStop="false"
   xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
   xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
   xmlns:local="using:CharmDemoApp"
   xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

   xmlns:cfo="using:CharmFlyoutLibrary"
   mc:Ignorable="d">
    <Grid>
        <cfo:CharmFlyout
           x:Name="cfoSettings"
           Heading="My Flyout"
           HeadingBackgroundBrush="#FF4E0000">
            <StackPanel>
                <TextBlock
                   FontSize="16">CharmFlyout by John Michael Hauck</TextBlock>
                <TextBlock
                   FontSize="16">For support:</TextBlock>
                <HyperlinkButton
                   Click="OnMailTo">support@bing.com</HyperlinkButton>
            </StackPanel>
        </cfo:CharmFlyout>
        <TextBlock
           VerticalAlignment="Center"
           HorizontalAlignment="Center"
           FontSize="25"
           Foreground="Blue">
                Swipe the right side of the screen to show the Settings Charm
                <LineBreak />
                <LineBreak />
                CharmFlyout Demo
                <LineBreak />

            <TextBlock.Transitions>
                <TransitionCollection>
                    <EntranceThemeTransition
                       FromVerticalOffset="400"
                       FromHorizontalOffset="0" />
                </TransitionCollection>
            </TextBlock.Transitions></TextBlock>
    </Grid>
</Page>

The location of the CharmFlyout should be such that it occupies the entire MainPage. That is, don’t embed it inside of a StackPanel or otherwise restrict its size.

Add the code-behind in MainPage.xaml.cs as shown here:

using System;
using Windows.UI.ApplicationSettings;
using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls;

namespace CharmDemoApp
{
    public sealed partial class MainPage : Page
    {
        public MainPage()
        {
            this.InitializeComponent();
            SettingsPane.GetForCurrentView().CommandsRequested += CommandsRequested;
        }

        private void CommandsRequested(SettingsPane sender, SettingsPaneCommandsRequestedEventArgs args)
        {
            args.Request.ApplicationCommands.Add(new SettingsCommand("s", 
                     "My Flyout", (p) => { cfoSettings.IsOpen = true; }));
        }
    }
}

That's it.  When you run your application, you will see "My Flyout" in the settings charm, and when you click “My Flyout”, this will fly out:

Here is a comparison of the CharmFlyout vs. the Permissions flyout:
