RadGridView Sorting problems

[Mohammad Masoud]

hi ,

im using a RadGridView with a silverlight datapager  using domain data source

and it worked but when i attempt to sort this error appears :

((cannot change observablecollection during a collectionchanged or a property changed event))

any ideas??
thank you all.
this is the code::

           

DomainContext context = new DomainContext();

            datasource.QueryParameters.Clear();
            datasource.QueryName = "GetEntities";

            datasource.QueryParameters.Add(new Parameter() { ParameterName = "direction", Value = _direction });

            if (datasource.DomainContext == null)
            {
                datasource.DomainContext = context;
            }

            datasource.PageSize = 10;

            datasource.LoadSize = 10;



            datasource.AutoLoad = true;
            datasource.Load();
            datasource.LoadedData += new EventHandler<LoadedDataEventArgs>(datasource_LoadedData);

  void datasource_LoadedData(object sender, LoadedDataEventArgs e)
        {




            DataGrid.ItemsSource = null;
            Pager.Source = null;
           DataGrid.ItemsSource =datasource.Data;
           Pager.Source = datasource.Data;
        }

Hello Mohammad Masoud,

It is working as expected in our RIA Services online demo. Can you check it?
