New Post: Property Grid : Additional information: Parameter count mismatch.

Hi ,

I have ViewModel class object , which nested type from lot of other models class.
when i am binding View object to property grid data context .
everythings work okay , but when i add collection inside collection , its showing problem.

Below is my simple code.:

Model class 1: CEnumVal.cs

public class CEnumVal
{
    private string _ord;

     public string Ord
    {
        get { return _ord; }
        set { _ord = value; }
    }

    public CEnumVal()  //ctor
    {}

}

Model Class 2 : CEnumType.cs

public class CEnumType
{
    private string _id;
    private ObservableCollection<CEnumVal> _enumValList;


    [ExpandableObject] 
    public ObservableCollection<CEnumVal> EnumValList
    {
        get { return _enumValList; }
        set
        {
            _enumValList = value;               
        }
    }

    public CEnumType()    //ctor
    {
       EnumValList = new ObservableCollection<CEnumVal>();
    }

Model Class 3 : CConfiguration.cs

public class CConfiguration 
{    
    private ObservableCollection<CEnumType> _dataTypeTemplates;

    [ExpandableObject]
    public ObservableCollection<CEnumType> DataTypeTemplates
    {
        get { return _dataTypeTemplates; }
        set
        {
            _dataTypeTemplates = value;

         }
    }

    public CConfiguration()  // ctor
    {
                   DataTypeTemplates = new ObservableCollection<CEnumType>();

    }

View Model class :
CConfigurationViewModel.cs

public class CConfigurationViewModel 
{
    private CConfiguration _ConfigrObj;

    [ExpandableObject]
    public CConfiguration ConfigrObj  
    {
        get { return _ConfigrObj; }
        set
        {
            _ConfigrObj = value;            
        }
    }



    public CConfigurationViewModel()  //ctor
    {
        ConfigrObj = new CConfiguration();

    }

View class

    public CConfigurationView()
    {
        InitializeComponent();

        CConfigurationViewModel _vmConfiguration = new CConfigurationViewModel();

        this.DataContext = _vmConfiguration;

      }

CConfigurationView.Xaml

<xctk:PropertyGrid x:Name="_propertyGrid" Width="Auto" Height="Auto" Margin="10" 
 SelectedObject="{Binding}" />
