binding to a list within list

I have a very simple problem. I have a list of cars and each car can further contain its name and a list of parts that consist the car. Now i want to show the cars(names) in a grid and the corresponding parts in a combobox in the same row using GridViewComboBoxColumn.
I have set the itemsource property of grid to Cars. Then i used the GridViewDataColumn's unique name to display the name and item source property of GridViewComboBoxColumn to display parts. Here is the code

<

telerik:RadGridView Name="UserListGrid" DockPanel.Dock="Top" Height="520"

ScrollMode="RealTime"

UseAlternateRowStyle="True"

AutoGenerateColumns="False"

ShowGroupPanel="False"

IsReadOnly="False"

RowIndicatorVisibility ="Visible"

CanUserFreezeColumns="False"

SelectionMode="Single"

ItemsSource="{Binding OperatorInfoItems, Mode=TwoWay}"

SelectedItem="{Binding SelectedRow, Mode=TwoWay}"

IsSynchronizedWithCurrentItem="True"

SelectionChanged="UserListGrid_SelectionChanged">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn UniqueName="Cars" DataType="{x:Null}" Header="Names" IsVisible="True" IsFilterable="False" IsGroupable="False" IsReadOnly="True" IsSortable="False" Width="150"/>

<telerik:GridViewComboBoxColumn ItemsSource="{Binding Parts}" Header="Parts"/>

</telerik:RadGridView.Columns>

</telerik:RadGridView>

But after running the project i could only see names and a data binding error message instead of a populated combobox.
Pl tell me what to do.

RadMap - DynamicLayer performance problem

Hi,
I was trying to use the dynamic layer and my goal was to only get items within the viewport. My data is stored with a quadkey up to lever 2^14 and because of that  I need to set the ZoomGrid to 2^level * 2^level cells.
    Looking with reflector in the the DynamicLayer code I've realized that the call back for getting the items for a particular cell is iterating through the entire cell set rather than being restirected to the one in the view.
This is obviously causing the application to freeze on high levels(9+). Am I missing something in my implementation?
   Are there any plans to introduce a DynamicLayer class that is similar with the Bing Tile system? I would take any beta version into consideration as where I am standing now I have to implement my own. Please advise!
Regards,
Dan

RadTabControl / RadTabItem events.

I have a small RadTabControl that has 3 RadTabItems as children. I've tried setting up the GetFocus events on the RadTabItem in both XAML and in code, but they do not fire. Has anyone else seen this issue?

Also, I tried to use the RadTabControl.SelectionChanged event as a work around, but that fires when the control loads, not just when the user changes selection so it didn't help.

GenericVista.xaml not found

I am in the process of evaluating the Telerik controls and have moved to trying to use them in our actual project. However, I cannot get a design time experience for any Rad control in Blend. I get an error in the results panel that reads: Cannot locate resource 'themes\genericvista.xaml'. I can create a standard out-of-the-box project and it works ok. Our project is a bit different. Here is the setup to hopefully find a solution:

VS2010, Blend 4, .Net 3.5
Telerik 2010.1.422.35

Our WPF exe project is separate from where we design. We have a Shell.exe project and it references our "Views.dll" project where all of the design takes place. Our shell project builds to a non-default location. It builds to ..\bin\Debug instead of bin\debug. We have also changed all project to have a build target platform of x86 instead of Any CPU. (Just pointing this out because you never know what might help get an answer).

My next step is to create an out of the box solution - get it to work with Telerik - and then step by step mirror what we are doing in our project. If I get the same error then I will have a solution I can upload it here. I am hoping someone can read this and help me with a solution before I go through all of that :)

Thanks.

Deleting a child in a Hierarchical Data Template

Hi, I have a database set up with a Client table and a Project table. Clients have projects, and I set up a Hierarchical Data Template to display them in the treeview. I am now putting functionality in for adding/removing both clients and projects, but I've run into an issue.

Adding and removing Clients (the parent nodes) will update the treeview immediately when I call the INotifyPropertyChanged on the ObservableCollection that it is bound to, but the Projects (the children nodes) won't update until I close the application and start it again.

Here is all the relevant code I can think of:

my xaml:

<Page.Resources>

<DataTemplate x:Key="Projects" DataType="{x:Type local:Project}">

<StackPanel Orientation="Horizontal">

<Image Source="/Images/Project.png" Height="20" Margin="0,0,8,0" />

<TextBlock Text="{Binding Name}" />

</StackPanel>

</DataTemplate>

<HierarchicalDataTemplate x:Key="Clients" DataType="{x:Type local:Client}" ItemTemplate="{StaticResource Projects}" ItemsSource="{Binding Projects}">

<StackPanel Orientation="Horizontal">

<Image Source="/Images/Client.png" Height="20" Margin="0,0,2,0" />

<TextBlock Text="{Binding Name}" />

</StackPanel>

</HierarchicalDataTemplate>

<Style x:Key="ItemContainerStyle" TargetType="{x:Type telerik:RadTreeViewItem}">

<Setter Property="Template" Value="{StaticResource SavanetekTreeItem}"/>

</Style>

</Page.Resources>

<telerik:RadTreeView x:Name="RadTreeView1" Grid.Row="1" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"

Style="{StaticResource SavanetekTreeViewStyle}" ItemsSource="{Binding ClientList}" SelectedItem="{Binding Path=SelectedObject, Mode=TwoWay}"

ItemTemplate="{StaticResource Clients}" ItemContainerStyle="{StaticResource ItemContainerStyle}">

<telerik:RadTreeView.ContextMenu>

<ContextMenu>

<MenuItem Header="New Client..." Click="MenuItemNewClientDetails_Click" />

<MenuItem Header="New Project..." Command="{Binding NewProjectCommand}" />

<Separator />

<MenuItem Header="Edit..." Click="MenuItemEditClientDetails_Click"/>

<Separator />

<MenuItem Header="Remove..." />

</ContextMenu>

</telerik:RadTreeView.ContextMenu>

</telerik:RadTreeView>

my remove function:

Public Sub Remove()

If (IsProject(SelectedObject)) Then

DB.Projects.DeleteOnSubmit(SelectedObject)

SubmitChangesToDatabase()

ElseIf (IsClient(SelectedObject)) Then

DB.Clients.DeleteOnSubmit(SelectedObject)

SubmitChangesToDatabase()

Else

End If

RefreshClientList()

End Sub

And my code for the ClientList with the Refresh and the function to cast the SelectedObject to a Client or a Project:

Private _clientList As ObservableCollection(Of Client)

Public Property ClientList() As ObservableCollection(Of Client)

Get

Return _clientList

End Get

Set(ByVal value As ObservableCollection(Of Client))

_clientList = value

OnPropertyChanged("ClientList")

End Set

End Property

Public Sub RefreshClientList()

ClientList = New ObservableCollection(Of Client)()

ClientList = ClientRepo.FindAll()

OnPropertyChanged("ClientList")

End Sub

I had tried putting a for each loop in the refresh function that listed all the projects in the ClientList, and it does in fact delete/add the Projects to it, so I know that it has the proper data. It just isn't displaying it for some reason.

I would greatly appreciate if anyone knows how to remove a child from a parent on the treeview and have it refresh
