I bind my grid to an EF4.1 object 

        public ObservableCollection<InventoryItem> InventoryItems
        {
            get
            {
                    if (!_loadComplete)
                        return null;
                    return _data.InventoryItems.Local;
            }
        }

- The load happens on a task thread 

             Task.Factory.StartNew(Load);

My problem is that if I turn off AutoGenerateFields, the all I ever see is the row selectors, never any column data.  

If I set AutoGenerateFields=True then it works as expected.

        <igDP:XamDataGrid Style="{StaticResource fadeIn}" Opacity="0"
            Name="grid" Theme="Office2k7Blue" DataSource="{Binding InventoryItems}" BindToSampleData="False"   >
            <igDP:XamDataGrid.ViewSettings>
                <igDP:GridViewSettings />
            </igDP:XamDataGrid.ViewSettings>
            <igDP:XamDataGrid.FieldSettings>
                <igDP:FieldSettings AllowRecordFiltering="True" 
                                    AllowEdit="True" 
                                    CellClickAction="EnterEditModeIfAllowed"  
                                    LabelClickAction="SortByMultipleFields" 
                                    FilterClearButtonVisibility="Visible" 
                                    LabelTextAlignment="Center" 
                                    LabelTextTrimming="CharacterEllipsis" 
                                    LabelTextWrapping="WrapWithOverflow" 
                                    FilterOperatorDefaultValue="Contains" />
            </igDP:XamDataGrid.FieldSettings>
 
            <igDP:XamDataGrid.FieldLayoutSettings>
                <igDP:FieldLayoutSettings AllowAddNew="True" AllowDelete="True" AutoGenerateFields="True" />
            </igDP:XamDataGrid.FieldLayoutSettings>
 
            <igDP:XamDataGrid.FieldLayouts>
                <igDP:FieldLayout IsDefault="true">
                    <igDP:FieldLayout.Fields>
                        <igDP:Field Name="item" Label="Item" Column="0" />
                        <igDP:Field Name="itmdesc" Label="Name" Visibility="Visible">
                            <igDP:Field.Settings>
                                <igDP:FieldSettings AllowGroupBy="False"   />
                            </igDP:Field.Settings>
                        </igDP:Field>
                        <igDP:Field Name="supplier" Label="Supplier"/>
                        <igDP:Field Name="stkumid" Label="Units"/>
                        <igDP:Field Name="price" Label="Price" />
                        <igDP:Field Name="price3" Label="Price3" />
                    </igDP:FieldLayout.Fields>
                </igDP:FieldLayout>
            </igDP:XamDataGrid.FieldLayouts>
        </igDP:XamDataGrid>

What am I doing wrong?
