I mean i need to bind unbound fields programmatically but i cannot manage to bind to a DataSource of type ObservableCollection<ObservableCollection<String>> sCol :

        <igDP:XamDataGrid x:Name="xamDataGrid" DataSource="{Binding sCol}">
            <igDP:XamDataGrid.FieldLayoutSettings>
                <igDP:FieldLayoutSettings AutoGenerateFields="False" />
            </igDP:XamDataGrid.FieldLayoutSettings>
            <igDP:XamDataGrid.FieldLayouts>
                <igDP:FieldLayout>
                    <igDP:FieldLayout.Fields>
                        <igDP:UnboundField Label="Col1" BindingPath="[0]" BindingMode="TwoWay" DataType="sys:String" />
                        <igDP:UnboundField Label="Col2" BindingPath="[1]" BindingMode="TwoWay" DataType="sys:String"/>
                    </igDP:FieldLayout.Fields>
                </igDP:FieldLayout>
            </igDP:XamDataGrid.FieldLayouts>
        </igDP:XamDataGrid>

Ouput traces say :

System.Windows.Data Error: 39 : BindingExpression path error: '[' property not found on 'object' ''EnumerableObjectWrapper' (HashCode=14407208)'. BindingExpression:Path=[1]; DataItem='EnumerableObjectWrapper' (HashCode=14407208); target element is 'a' (HashCode=44344604); target property is 'Value' (type 'Object')

I can achive a correct binding through a regular listView though :

        <ListView ItemsSource="{Binding sCol}">
            <ListView.View>
                <GridView>
                    <GridViewColumn Header="Col1" DisplayMemberBinding="{Binding [0]}"/>
                    <GridViewColumn Header="Col2" DisplayMemberBinding="{Binding [1]}"/>
                </GridView>
            </ListView.View>
        </ListView>

It seems that the grid DataSource property does not behave like the list ItemsSource property.

What am I missing ?

Cheers.
