Hi All,

I am new in the Wpf world, so I created a couple of views and all of them have at least one ComboBox, as I am using the MvvM pattern, I get my self re-typing all the time the same line of codes to fill the Combo and to get the SelectedItem (creating properties, privates for fill and other to get).

Is there some kind of framework that can improve this part ? or hack/trick ??? as I see too much repetitive code... maybe I am doing something wrong, take a look:

XAML:

<ComboBox name= "cbDepartments" DisplayMemberPath="DepartmentName"
                      SelectedValuePath ="PrimaryKey"
                      ItemsSource="{Binding Path=Departments}" 
                      SelectedItem="{Binding Path=DefaultBranch,Mode=TwoWay}" 
>

ViewModel:

private Department defaultBranch;
        public Department DefaultBranch
        {
            get
            {
                return this.defaultBranch;
            }

            set
            {
                if (this.defaultBranch != value)
                {
                    this.defaultBranch = value;
                    this.OnPropertyChanged("DefaultBranch");
                    this.saveChangeCommand.RaiseCanExecuteChanged();
                    this.UserMessage = string.Empty;
                }
            }
        }

private ObservableCollection<Department> departments; 
public ObservableCollection<Department> Departments
        {
            get { return this.departments; }
            set
            {
                if (this. departments!= value)
                {
                    this. departments = value;
                    this.OnPropertyChanged("Departments");
                }
            }
        }
