How to dynamically get the command and get the result

Hi,

Well first of all, you could have a look at the following: Creating a Generic Entity Framework 4.0 Repository[^] - this will allow you to create a generic repository which will accommodate any entity table class.

Secondly, as mentioned earlier you could do something like this:

I don't know if you are using MVVM or any other design pattern, so this is going to be a very basic example:

Our Interface:

public interface ISavable
{
    int SaveData();
}

Our first UserControl - which implement ISavable:

public partial class UserControl1 : UserControl, ISavable
{
    public UserControl1()
    {
        InitializeComponent();
    }

    #region ISavable Members

    public int SaveData()
    {
        using (DevelopmentEntities context = new DevelopmentEntities())
        {
            context.Events.AddObject(new Event());
            return context.SaveChanges();
        }
    }

    #endregion
}

Our second UserControl - which implements ISavable:

public partial class UserControl2 : UserControl, ISavable
{
    public UserControl2()
    {
        InitializeComponent();
    }

    #region ISavable Members

    public int SaveData()
    {
        using (DevelopmentEntities context = new DevelopmentEntities())
        {
            context.EventTypes.AddObject(new EventType());
            return context.SaveChanges();
        }
    }

    #endregion
}

Now, within our main class (where ever the ribbon control is instantiated), we need to cast the active user control to the interface and call the appropriate method - as mentioned earlier, this is a very basic example, but demonstrates the principle:

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();

        ISavable saveUserControl = this.DataContext as UserControl1;
        saveUserControl.SaveData();

        ISavable saveUserControl2 = this.DataContext as UserControl2;
        saveUserControl.SaveData();
    }
}

Needless to say you could extend this by making it more generic as well as implementing a MVVM pattern.

Hope it helps!
Kind regards,
