Im close to my solution but i cant figure out my last step. I have a RowDetailsTemplate for each row in a RadTreeListView. My Probplem is I can figure out how to bind it. Im binding it to CurrentSelected but now evrytime I click on a other row the RowDetailsTemplate changes ofcourse. MY XAML is to big to post it so I ll show some examples.
<RadTreeListView Name="positionenDataGrid"
HierarchyColumnIndex="3"
ItemsSource="{Binding Path=Model.ModelChildList}"
SelectedItem="{Binding Path=CurrenPosition}">
<RadTreeListView.ChildTableDefinitions>
<TreeListViewTableDefinition ItemsSource="{Binding PositionChildList}" />
</RadTreeListView.ChildTableDefinitions>
<RadTreeListView.Columns>
<columns:CustomToggleButtonColumn x:Name="ExpanderColumn" Header="DetailView" DataMemberBinding="{Binding IsPositionExpanded}" ToggleButtonVisibility="{Binding Path=CanHavePositionen}"/>
</RadTreeListView.Columns>
<RadTreeListView.RowDetailsTemplate>
<DataTemplate>
<Views:DetailPositionView HorizontalAlignment="Left" />
</DataTemplate>
</RadTreeListView.RowDetailsTemplate>
</RadTreeListView>
Example of Binding in DetailPositionView;:
Value="{Binding RelativeSource={RelativeSource Mode=FindAncestor,AncestorType={x:Type Views:ParentView}}, Path=DataContext.CurrenPosition.Number}"
If I open two RowDetailsTemplates at the same time they have both the same Content because I bind on the SelectedItem. The question now is: How can I give them each Data of each Row without SelectedItem?
DataContext of your DetailPositionView is the row data. So just doing
Value="{Binding Number}"
will do the trick
