Possibility to known the STorageId

[Oliver]

Hi,

I have a generic class to persist (load/save) RadControls from/to disk and I in my class I catch different exceptions. I would like to know if it's possible to know the StorageId my class trying to persist because when I'm catching an exception, I would like to log the StorageId in my log file?

Thank's

Here is my 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>

        {
            mErrorMessage = e.Exception.Message;
            mResult = false;
            throw new NotImplementedException();
        }

        /// <summary>

        static void manager_PropertyPersisting(object sender, Telerik.Windows.Persistence.Events.PersistingPropertyEventArgs e)
        {
            //Not needed since version 2011.3.1116.35 of Telerik
            //if (e.Name == "BorderBrush")
            //    e.Cancel = true;
        }
        #endregion

        #region Enumerators.
        public enum PersistenceAction { Load, Save }
        #endregion

Hello Oliver,

Currently, this scenario is not supported. The PersistenceError event args do not provide information about the root object which is being saved. If the property is on the root level (property of the control that you are serializing) then you could get its serialization id. However, if the property is nested, then you have only the proeprty's name and path.
We logged a feature request in our PITS and now you are able to vote for, this way increasing its development priority.
