Hi.

I have an issue to bind two custom classes with comboboxColumn.

My custom classes in viewmodel are below:

public class Logic{                                    // this is available selections in combobox column

    privae int no

    private string desc;

    public int No { //getter, setter }

    public string Desc { //getter, setter}

}

private ObservationCollection<Logic> lstLogic;

public ObservationCollection<Logic> LstLogic { // getter, setter }

public class DetailInfo{                                  // this includes real data for showing in grids

   public int idx {get;set;}

   public string name {get; set;}

   ...

   public int logic_no {get;set;}                    

   public string logic_desc {get;set;}               // first selected desc in combobox

}

private ObservationCollection<DetailInfo> lstInfo;

public ObservationCollection<DetailInfo> LstInfo { // getter, setter }

And, in my xaml I binded my custom classes like this.

<ig:XamGrid x:Name="xamGridInfo" ItemSource="{Binding Path=LstInfo, NofityOnTargetChanged=True}">

    <ig:XamGrid.Columns>

        <ig:TextColumn Key="idx" HeaderText="idx" Width="*" IsReadOnly="True"/>

        <ig:TextColumn Key="name" HeaderText="idx" Width="*" IsReadOnly="True"/>

        <ig:ComboBoxColumn Key="logic_desc" HeaderText="logic" ItemsSource="{Binding LstLogic}" DisplayMemberPath="Desc" SelectedValuePath="Desc"/>

    </ig:XamGrid.Columns>

</ig:XamGrid>

Other text columns are shown well, but only a combobox column shows nothing in it.

Also, I got this bug message:

System.Windows.Data Error: 2 : Cannot find governing FrameworkElement or FrameworkContentElement for target element. BindingExpression:Path=LstLogic; DataItem=null; target element is 'ComboBoxColumn' (HashCode=608860); target property is 'ItemsSource' (type 'IEnumerable')

What should I do..?

I appreciate for your help in advance.
