(Experimental) GraphPresenter XAML Control

The GraphPresenter is a flexible XAML control for visualizing Graph API data. Provide an IBaseRequestBuilder implementation and the GraphPresenter will automatically fetch the data from the proper Graph endpoint, ready for visualization. Because every Graph entity is different, this control has no default UI of it's own. It is up to the developer to decide how the data should be presented by setting the control's ContentTemplate. This control is great for prototyping and experimentation purposes, but we suggest creating your own user controls for production scenarios.

Available in the CommunityToolkit.Graph.Uwp package.

Syntax

XAML

<!-- Display my recent OneDrive files. -->
<Grid xmlns:controls="using:CommunityToolkit.Graph.Uwp.Controls">
    <controls:GraphPresenter 
            RequestBuilder="{x:Bind RecentDriveItemsRequestBuilder, Mode=OneWay}"
            ResponseType="graph:DriveItem"
            IsCollection="True">
        <controls:GraphPresenter.ContentTemplate>
            <DataTemplate>
                <!-- Return result is a collection of DriveItems as we used 'IsCollection', so bind that first. -->
                <ItemsControl ItemsSource="{Binding}">
                    <ItemsControl.ItemTemplate>
                        <DataTemplate x:DataType="graph:DriveItem">
                            <TextBlock Text="{Binding Name}" />
                        </DataTemplate>
                    </ItemsControl.ItemTemplate>
                </ItemsControl>

Code-behind

public IBaseRequestBuilder RecentDriveItemsRequestBuilder { get; set; }

public GraphPresenterSamplePage()
{
    InitializeComponent();

    ProviderManager.Instance.ProviderStateChanged += (s, e) => UpdateRequestBuilder();
    UpdateRequestBuilder();
}

private void UpdateRequestBuilder()
{
    var provider = ProviderManager.Instance.GlobalProvider;
    switch (provider?.State)
    {
        case ProviderState.SignedIn:
            RecentDriveItemsRequestBuilder = provider.GetClient().Me.Drive.Recent();
            break;

        default:
            RecentDriveItemsRequestBuilder = null;
            break;
    }
}
