I bound standard ListBox to ObservableCollection<XmlDataProvider>, then set:

<ListBox ItemTemplate="{StaticResource SimpleDataTemplate}">

"SimpleDataTemplate" is defined as follows:

<DataTemplate x:Key="SimpleDataTemplate" DataType="XmlDataProvider">

<DockPanel Name="mdockElementHolder">

                <igDP:XamDataGrid DataSource="{Binding XPath=//Elements/Element}"

                                        AutoFit="True"

                                        GroupByAreaLocation="None"

                                        ScrollingMode="Immediate"

                                        RecordLoadMode="PreloadRecords"

                                        RecordContainerGenerationMode="PreLoad"

                                        CellContainerGenerationMode="PreLoad">

...

I also implemented manual field layout of XamDataGrid:

<igDP:XamDataGrid.FieldLayouts>

                        <igDP:FieldLayout Key="Key_Elements" >

                            <igDP:FieldLayout.Settings>

                                <igDP:FieldLayoutSettings DataRecordCellAreaStyle="{StaticResource TopItemRecordCellAreaStyle}">

                                    <igDP:FieldLayoutSettings.DataRecordCellAreaGridTemplate>

                                        <ItemsPanelTemplate>

                                            <Grid>

                                                <Grid.ColumnDefinitions>

                                                    <ColumnDefinition Width="200" />

                                                    <ColumnDefinition Width="50" />

                                                    <ColumnDefinition Width="250" />

                                                </Grid.ColumnDefinitions>

                                                <Grid.RowDefinitions>

                                                    <RowDefinition />

                                                    <RowDefinition />

                                                    <RowDefinition />

                                                </Grid.RowDefinitions>

                                            </Grid>

                                        </ItemsPanelTemplate>

                                    </igDP:FieldLayoutSettings.DataRecordCellAreaGridTemplate>

                                </igDP:FieldLayoutSettings>

                            </igDP:FieldLayout.Settings>

                            <igDP:FieldLayout.Fields>

                                <igDP:Field Name="Name" Label="NAME" Column="0" Row="0" DataType="{x:Type sys:String}">

                                </igDP:Field>

                                <igDP:Field Name="DataType" Label="TYPE" Column="1" Row="0" DataType="{x:Type sys:String}">

                                </igDP:Field>

                                <igDP:Field Name="IsSelected" Label="Is Selected" Column="1" Row="1" DataType="{x:Type sys:String}" Visibility="Hidden">

                                </igDP:Field>

                                <igDP:Field Name="IsSortBy" Label="Is Sort By" Column="0" Row="1" DataType="{x:Type sys:String}">

                                </igDP:Field>

                                <igDP:Field Name="Description" Label="DESCRIPTION" Column="0" Row="3" ColumnSpan="2" DataType="{x:Type sys:String}">

                                </igDP:Field>

                                <igDP:Field Name="Condition" Label="Condition" Column="2" Row="0" RowSpan="3" DataType="{x:Type sys:String}">

                                </igDP:Field>

                            </igDP:FieldLayout.Fields>

                        </igDP:FieldLayout>

                    </igDP:XamDataGrid.FieldLayouts>

Form constructor instantiates ObservableCollection and adds few XmlDataProviders.

Problem arises when this form is shown. Only first ListBoxItem contains properly formatted XamDataGrid. All other ListBoxItems show blank XamDataGrid.

What am I doing wrong?

Thank you
