How do you store application data in a UWP project?

You can store and retrieve composite application data in a UWP project using the Windows Storage. Specifically you will be using the Windows.Storage.ApplicationDataCompositeValue sealed class shown in the Object Browser.

In this post a project is described where in a pair of values are stored in the Windows Storage's local folder and retrieved. The values are stored using a button click event of a button and retrieved into text boxes in the click event of a second button.

The MainPage.xaml for the project is as shown.

The code for storing and retrieving is shown in the MainPageXAMLCs. You first define the local settingss using the Windows.Storage.ApplicationDataContainer and the local folder. The composite values are set to the local settings.

The retrieving is by extracting the values in the local settings and reading it into a text box.

The result of running the application is shown here.

The code can be simplified as suggested by the hint shown here:

How do you use a SplitView XAML control in a UWP Project?

You can get a basic start with the SplitView Control here.

You could replace the default 'grid' in a Blank UWP project shown here:

Use the following in its place:

This is ready for build. Build and run the app in the Local Computer.
This is what you see when the app is run.

There is a Pane (the SplitView. Pane and there is a TextBlock named 'Content' in the Grid.

Now I change the OpenPanelLenth (presently 296) to, say 150 and build and run the app. What do I see?

SplitView 2

Basically you can now see more content.

In the 'Pane' you can place controls and hook up events to them to display related 'Content' in the Content (i.e., inside the 'grid' control).
