Possibility to clear settings

[Tau Sick]

Sometimes the users paint themselves into a corner and set up the UI in an unwanted way. I would like a way to clear settings (all would be fine, but the ability to clear only some would also be better).

Something like

 

           IsolatedStorageProvider isoProvider = new IsolatedStorageProvider();

           isoProvider.ClearStorage();

           isoProvider.ClearStorage(“myGridView”);

This would remove the files from isolated storage and revert controls to default settings.

Hi Tau Sick,

If you want to delete a particular file with settings, you can use the following code :

using (var store = IsolatedStorageFile.GetUserStoreForAssembly())
{
    string fileName = "myGridView" + ".bin";
    if (store.FileExists(fileName))
    {
        try
        {
            store.DeleteFile(fileName);
        }
        catch (Exception ex)
        {
        }
    }
}

However, we had already considered this request and had implemented part of it. We added a method for deleting all of the saved settings in the IsolatedStorage for the application - IsolatedStorageProvider.DeleteIsolatedStorageFiles. It will be publicly available with the upcoming internal build.
Please let me know if you have questions on this matter.

Hi Tau Sick,

In case you would like to extend the IsolatedStorageProvider class or create an extension method, you can use the PersistenceManager.GetStorage() method, which will return the registered controls with their storage ids.

Perfect - that takes care of deleting the files.

But can I revert the settings of my UI to default without having to restart the application?

Hi Tau Sick,
 
Can you please elaborate on what you mean by restarting the application? Basically you can save the initial state of your user control on loading it for example and then you can load the persisted state using the PersistenceManager.Load method like described in this article.

All the best,

ok, sorry - I guess I don't need to restart, I can just reload settings.
