Selection Handling on Design Surface

[khalili-mahdi]

i'm using this code to change SelectionChanged handler on DesignSurface

 designSurface.DesignContext.Services.Selection.SelectionChanged += delegate
            {
                   var selection = designSurface.DesignContext.Services.Selection.SelectedItems.First().Component ;
                   CommandManager.InvalidateRequerySuggested();
            };

i feel like its wrong what is the correct way to do this in DesignSurface ? i need to get data from Selected Item but its not DesignItem , i've Added My own Control to it

Again, I don‘t understand the question! But you could use PrimarySelection instead of SelectedItems
