Partially Bound RadTreeView

I'm attempting (with limited success) to create a TreeView that contains a mixture of dynamic and static data.

You'll find my current best attempt at this below, however since I'm nesting TreeViews there is a side effect wherein it is possible to have multiple items within the parent TreeView selected. When I've tried nesting TreeViewItems the results were not positive, i.e. only the parent level TreeViewItem in the ItemTemplate is displayed and space for it's children is created but nothing is output.

I would really like to know how to acheive my goal without resorting to specifying the entire menu in collections which I bind to the TreeView.

Thank you

Does anyone have any explanation for what's going on? I'm not using the "my" prefix anywhere in my code.

NullReferenceException when changing the selected date

Hi.
I use RadCalendar in my project for selection date.

<telerik:RadCalendar HeaderVisibility="Collapsed" Height="150"

SelectableDateStart="{Binding SelectedDateStart}"

SelectableDateEnd="{Binding SelectedDateEnd}"

SelectedDate="{Binding Date, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}"/>

public class NextActionDate : INotifyPropertyChanged

{

public DateTime SelectedDateStart { get; set; }

public DateTime SelectedDateEnd { get; set; }

private DateTime date;

public DateTime Date

{

get

{

return date;

}

set

{

date = value;

GenerateEvent("Date");

}

}

public event PropertyChangedEventHandler PropertyChanged;

private void GenerateEvent(string inName)

{

if (PropertyChanged != null)

{

PropertyChanged(this, new PropertyChangedEventArgs(inName));

}

}

}

Usually it works correctly.

But sometimes I have exceptions:

LegendLabel Binding

I'd like to databind the LegendLabel to a field of my viewmodel.
<telerikCharting:SeriesMapping LegendLabel="{Binding ViewModelField}" >

When opening my window the Legend displays "Series 0" instead of the value from my ViewModelField. When I refresh the View by updating the ItemsSource of the RadChart control I get the LegendLabel value I want.

Any ideas of what is going wrong?
I'm using the Q1/2011 WPF chart control.

CellEditTemplate TabNavigation

I have a CellEditTemplate that contains a UserControl composed of two comboboxes. I wish to have the first combobox selected when I tab into the cell, then have the second combobox selected with the next tab. (Keyboard focus so that arrow keys can move through the items in the combobox)

Both comboboxes have their IsTabStop properties set to True. The control in the CellEditTemplate (DataTemplate) has its IsTabStopProperty set to true.

How can I accomplish this?

Thank you in advance,
Scott Lee
