I have 2 forms, FormA & FormB, both was created but only one at a time can be visible. Each form have an existing StoradId property. When I click on my button "Save persistence" in my FormB, both forms persistence are save at the same time on disk???
If it's normal, can you tell me if it's possible to only save the persistence of the form from where the code is called?
Here is my persistence class:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Telerik.Windows.Persistence;
using Telerik.Windows.Persistence.Storage;
namespace WpfApplication_Docking
{
static public class PersistenceStorage
{
#region Public methods.
/// <summary>
/// Load/Save all controls that contain "telerik:PersistenceManager.StorageId="..."
/// The file location is "$APPDATA\IsolatedStorage\..."
/// </summary>
/// <param name="pPersistenceAction">Load/Save</param>
/// <param name="pErrorMessage">Error received during the persistence.</param>
/// <returns>true if successfull otherwise false</returns>
static public bool Persist(PersistenceAction pPersistenceAction, out string pErrorMessage)
{
pErrorMessage = string.Empty;
PersistenceManager manager = new PersistenceManager();
//manager.PropertyPersisting += new Telerik.Windows.Persistence.Events.PropertyPersistingEventHandler(manager_PropertyPersisting);
IsolatedStorageProvider storage = new IsolatedStorageProvider(manager);
try
{
try
{
if (pPersistenceAction == PersistenceAction.Load)
{
storage.LoadFromStorage();
}
else if (pPersistenceAction == PersistenceAction.Save)
{
storage.SaveToStorage();
}
return true;
}
catch (Exception ex)
{
pErrorMessage = ex.Message;
return false;
}
}
finally
{
//manager.PropertyPersisting += new Telerik.Windows.Persistence.Events.PropertyPersistingEventHandler(manager_PropertyPersisting);
}
}
/// <summary>
/// Event triggered when the stream persistence didn't worked.
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
static void manager_PersistenceError(object sender, Telerik.Windows.Persistence.Events.PersistenceErrorEventArgs e)
{
mErrorMessage = e.Exception.Message;
mResult = false;
throw new NotImplementedException();
}

{
//Not needed since version 2011.3.1116.35 of Telerik
//if (e.Name == "BorderBrush")
// e.Cancel = true;
