How to bind a single view to multiple ViewModels properly?

Question

I have a view which has bindings like:

<TextBlock Text="{Binding Attribute1, Mode=TwoWay}" />
<TextBlock Text="{Binding Attribute2, Mode=TwoWay}" />

Also I have tons of view models where dependency properties are called somehow ( Name , OfficialName , etc), but essentially they are Attribute1 , so I want to use the same view to show them to a user. All the bindings should be two-way. I was thinking about creating a temporary class like:

public class AttributesInfo
{
   string Attribute1{ get; set; }
   // other attributes
}

and expose in every view model a property Attributes :

return new AttributesInfo{ Attribute1 = Name, ... };
return new AttributesInfo{ Attribute1 = OfficialName, ... };

which would supply a view:

<TextBlock Text="{Binding AttributesInfo.Attribute1, Mode=TwoWay}" />

Now I am thinking about two-way bindings and I understood that this is a wrong solution. Is there any good one?

Better would be if you create an Interface with the required attribute properties and implement it in different VMs.

eg

public interface IAttribute
{
   string Attribute1 {get; set;}
   .
   .
   .
}

public class someVM : IAttribute
{
  private string _name;
  public string Nam
  {
     get {return _name;}
     set
     {
        _name = value;
        NotifyPropertyChanged("Name");
                 }
  }

  public string Attribute1
  {
     get{return this.Name;}
     set
     {
        this.Name = value; 
        NotifyPropertyChange("Attribute1");
     }
  }
}

In this way your properties will be in sync with the attributes and you can use same view for all VMs.
