ViewModel

    public class LoginModel : ViewModelBase
    {

    public string txtLabel_IsFocused { get; set; }                 
    public string butEdit_IsEnabled { get; set; }                


    public void SetProperty(string PropertyName, string value)
    {
        System.Reflection.PropertyInfo propertyInfo = this.GetType().GetProperty(PropertyName);
        propertyInfo.SetValue(this, Convert.ChangeType(value, propertyInfo.PropertyType), null);
        OnPropertyChanged(PropertyName);
    }                


    private void Example_function(){

        SetProperty("butEdit_IsEnabled", "False");
        SetProperty("txtLabel_IsFocused", "True");        
    }

    }
