SetStorageId property

[pat]

I am trying to use the PersistenceFramework and I would like to set the StorageId progamatically.  I am try to give the user the opportunity to save several 'versions' of a gridview.  Is this possible?  According to the docs it would seem that the SetStorageId property is part of the PersistenceManager but it does not show up. Could I get some sample code on this.

Thanks,

PatC

Hello Pat,

Yes, it is possible to keep several versions of one control  by changing its StorageId property. You can change the StorageId value in procedural code by using the static method PersistenceManager.SetStorageId(...) and pass the object and the new string value for storage id. Please note that the StorageId is an attached dependency property, and the static method of the owner class is how you set its value.

PersistenceManager.SetStorageId(this.textBox, "textBox_Version1);

Hi,

In my application, I have a composite view of RadTileViewItem; This view can be accessed by multiple undefined users.
I would like each of them to save their configuration.

So I think using the method:
"PersistenceManager.SetStorageId" with the user ID as a key storage.

My question is:

How, according to the user find the right persistence of control, from "ISO".

With the method "GetStorageId" I can not get the proper configuration.
Can you help me?
Here my code XAML:

<telerik:RadTileView x:Name="WidgetTileView" ItemsSource="{Binding RadWidgetPanels}"
                     RowHeight="*" ColumnWidth="*" MinimizedColumnWidth="350"
                     ReorderingDuration="0:0:1" ResizingEasing="{StaticResource ResizingEase}" ReorderingEasing="{StaticResource ResizingEase}" />

<Button Content="SaveToIsolateStorage" Click="OnSave" Grid.Row="1"></Button>

And the code behind:

public partial class AccueilView : UserControl
{
    private AccueilViewModel currentDataContext;
    private IsolatedStorageProvider isoProvider = new IsolatedStorageProvider();

    public AccueilView()
    {
        InitializeComponent();

        this.DataContext = new AccueilViewModel();
        this.currentDataContext = (AccueilViewModel)this.DataContext;

        this.Loaded += new RoutedEventHandler(AccueilView_Loaded);
    }

    void AccueilView_Loaded(object sender, RoutedEventArgs e)
    {
        PersistenceManager.GetStorageId(this.WidgetTileView);
        this.isoProvider.LoadFromStorage();
    }


    void OnSave(object sender, System.Windows.RoutedEventArgs e)
    {
        var key = string.Concat("Widget_", this.currentDataContext.CurrentUserId);
        PersistenceManager.SetStorageId(this.WidgetTileView, key);
        this.isoProvider.SaveToStorage();
    }

}

Hello Bonin,

I have attached a small project demonstrating this requirement. The radio buttons on top simulate different users and generate different storage ids based on which user is active. Then with the Save and Load buttons, the appropriate configuration is saved and loaded on the slider control below. Please let me know if you have questions on this.
