thanks a lot for your answer I need to stop binding when I call BeginEdit method this method in Csla so I read in CSLA Book " [[if you want to use the undo feature manually you have to call BeginEdit before you bind the object to UI and you have to Rebind the object after canceling or applying changes made to the object]] " that's why I asked about pausing or stopping binding to UI Maybe I misunderstood the CSLA Undo Feature. any way after applying changes I rebinded the object to UI and work fine so thanks You have To Search About The Truth Of Your Life Why Are you Here In Life ?

Okay I found the answer I made two mistakes in previous thread: 1- I forget to set the source property for each Binding object 2- I called setBinding method for media Element before adding it to the window window contain button1 this code is wrong MediaELement M = new MediaElement(); Binding SourceDataBinding = new Binding(); SourceDataBinding.Source = data; // data is variable that contain the data to bind SourceDataBinding.Mode = BindingMode.OneWay; Binding SourceExtentionBinding = new Binding(); SourceExtentionBinding.Source = Extension; // extension is variable that contain the data to bind SourceExtentionBinding.Mode = BindingMode.OneWay; Binding SourcePathBinding = new Binding(); SourcePathBinding.Mode = BindingMode.OneWay; SourcePathBinding.Source = \_filePath; // \_filePath is variable that contain the data to bind MultiBinding SourceBinding = new MultiBinding(); SourceBinding.Bindings.Add(SourceDataBinding); SourceBinding.Bindings.Add(SourceExtentionBinding); SourceBinding.Bindings.Add(SourcePathBinding); SourceBinding.Converter = new ReferenceConverter(); M.SetBinding(MediaElement.SourceProperty, SourceBinding); this.button1.Content = M; this code is right this.button1.Content = M; MediaELement M = new MediaElement(); Binding SourceDataBinding = new Binding(); SourceDataBinding.Source = data; SourceDataBinding.Mode = BindingMode.OneWay; Binding SourceExtentionBinding = new Binding(); SourceExtentionBinding.Source = Extension; SourceExtentionBinding.Mode = BindingMode.OneWay; Binding SourcePathBinding = new Binding(); SourcePathBinding.Mode = BindingMode.OneWay; SourcePathBinding.Source = \_filePath; MultiBinding SourceBinding = new MultiBinding(); SourceBinding.Bindings.Add(SourceDataBinding); SourceBinding.Bindings.Add(SourceExtentionBinding); SourceBinding.Bindings.Add(SourcePathBinding); SourceBinding.Converter = new ReferenceConverter(); M.SetBinding(MediaElement.SourceProperty, SourceBinding); You have To Search About The Truth Of Your Life Why Are you Here In Life ?

I found another solution and I think it is easier and maybe better for my needs Expression Filter; // this the expression that may have many internal Conditions Expression Result = Expression.Call(Expression.Property(Filter,"FirstName") ,typeof(string).GetMethod("Contains") ,new Expression[] {Expression.Constant("fe" ,typeof(string))} ); I found this code in LinqInAction Book Page 498 Thanks Again mr Eslam Afifi I hope to be friends :) You have To Search About The Truth Of Your Life Why Are you Here In Life ?
