Weird exception when viewing design

I've got a window that contains a RadSplitButton control in it. Here's a snippet of the code surrounding the RadSplitButton:

When the program runs, everything works fine and the window displays without any errors. But, when I view the window in the Designer panel in Visual Studio 2010, an exception is reported!

Here's the exception that appears instead of the rendering of the window:

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,

GridView grouping throws ArgumentOutOfRangeException

Hello,

We just updated our telerik-controls to the latest version (2011 Q1). Now I am getting an exception when trying to use the gridview grouping.

This is the xaml for my gridview :

<telerik:RadGridView AutoExpandGroups="True" ShowColumnHeaders="False"

ItemsSource="{Binding SelectedCategoryDataItems}"

CanUserFreezeColumns="False" CanUserReorderColumns="False"

CanUserResizeColumns="False"

EditTriggers="None" IsReadOnly="True"

AutoGenerateColumns="False"

ActionOnLostFocus="None" RowIndicatorVisibility="Collapsed"

ShowGroupPanel="False"

HorizontalAlignment="Stretch" Grid.Column="1"

RowStyle="{StaticResource GridItemStyle}"

/>

The SelectedCategoryDataItems property is a QueryableCollectionView. The groupdescriptor is added from the viewmodel code-behind :

DataItems.GroupDescriptors.Add(new GroupDescriptor() { Member = "Status2" });

When I set AutoExpandGroups = True, the following exception is immediately thrown (application doesn't start) :

Hierarchical grid view from hierarchical object

I have a WPF gridview in which I specify the datacolumns and load the data simply with (C#)::

gridFeeEarnerGroups.ItemsSource = Bill.FeeEarnerGroups;

"FeeEarnerGroups" is of type List<FeeEarnerGroup> and this works fine.

I need a sub table to use the data from FeeEarnerGroup.RateSets which is of type List<RateSet> , showing each (0 or more) RateSet per FeeEarnerGroup row.

I've looked at the documentation and tried a few things but I'm struggle to get this working.
Can anyone help please?
