Hello,

Using Telerik version 2013.2.611.40, i'm trying to export a (grouped) grid which contains only 1 column, that has a nested items control in a GridViewDataColumn.CellTemplate. The result (ExcelML) file doesn't contain the values from the nested list.

The result (in GUI) is just what i want (and need) the problem is with the export.

* I need to be able to export to ExcelML and to display (in GUI) the data grouped like this:
^Name
some key some value
some key2 some value2
^Name2
some key3 some value3
some key4 some value4
* the 'Items' (and SourceAttributes) is an ObservableCollection of my custom view model

(part) of the xaml:

<UserControl...

<xmlns:telerik="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.GridView"

...>

<DataTemplate x:Key="sourceAttributesDataTemplate">

<ItemsControl ItemsSource="{Binding Path=SourceAttributes}">

<ItemsControl.ItemsPanel>

<ItemsPanelTemplate>

<StackPanel Orientation="Vertical"/>

</ItemsPanelTemplate>

</ItemsControl.ItemsPanel>

<ItemsControl.ItemTemplate>

<DataTemplate>

<Grid>

<Grid.ColumnDefinitions>

<ColumnDefinition Width=".3*"/>

<ColumnDefinition Width=".7*"/>

</Grid.ColumnDefinitions>

<Label Grid.Column="0" Content="{Binding Path=Key}"/>

<Label Grid.Column="1" Content="{Binding Path=Value}"/>

</Grid>

</DataTemplate>

</ItemsControl.ItemTemplate>

</ItemsControl>

</DataTemplate>

<telerik:RadGridView ItemsSource="{Binding Path=Items}" AutoGenerateColumns="False" GroupRenderMode="Flat" AutoExpandGroups="False" ShowColumnHeaders="False">

<telerik:RadGridView.GroupDescriptors>

<data:GroupDescriptor Member="Name" SortDirection="Ascending" />

</telerik:RadGridView.GroupDescriptors>

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn Width="*" Header="" CellTemplate="{StaticResource sourceAttributesDataTemplate}">

</telerik:GridViewDataColumn>

</telerik:RadGridView.Columns>

</telerik:RadGridView>

Is there any way to achieve this functionality? (where is the problem?)
I know that 'DataMemberBinding' is crucial - but in this case they are nested inside the ItemsControl....

Thanks in advance,
Aviv
