  • Hi Every one ,

      public string Module
                get { return (string)GetValue(ModuleName); }
                    SetValue(ModuleName, value);
            public static readonly DependencyProperty ModuleName =
                DependencyProperty.Register("Module", typeof(string), typeof(UcPhotos),
                new PropertyMetadata(string.Empty, OnModuleNameChanged));
            private static void OnModuleNameChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
                (d as UcPhotos).ModuleId = e.NewValue.ToString();
                (d as UcPhotos).id = e.NewValue.ToString();
     private string _ModuleId;
            public string ModuleId
                { return _ModuleId; }
                    if (_ModuleId == value)
                    ((UcPhotoViewModel)this.DataContext).Module = value.ToString();

  • Hi Shivam,

    I am not sure what are you doing about the binding. Does you want to edit the Module property of the UcPhotos control to change something else? There is less information for me to understand your problem.

    Can you send a project for reproduction? Use your OneDrive and share a link here. I will look into it.

    Thank you for understanding.
