RadGridView export for nested ItemsControl

[Aviv]

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

Hello Aviv,

I would suggest you to check this troubleshooting article, which demonstrates how to export custom CellTemplate.
