Set GridViewComboBoxColumn ItemsSource on Got Focus

Hi

I trying to set GridViewComboBoxColumn itemsSource when GotFocus event is fired but it doesn't work.
I ' m using Q2 2010 SP1 libraries and I put

this.AddHandler(RadComboBox.GotFocusEvent, new RoutedEventHandler(comboGotFocus));

in the control constructor while the handler is

void comboGotFocus(object sender, RoutedEventArgs args)

{

GridViewCell cell = args.OriginalSource as GridViewCell;

if (cell != null && cell.Column.UniqueName == "RegionId")

{

District district = cell.DataContext as District;

if (district != null && cell.Content is LookupElement)

{

string countryId = district.CountryId;

RadGridView gridView = (RadGridView)this.districtRegistryControl.ChildrenOfType<RadGridView>().First();

RadComboBox comboBox = (cell.Content as LookupElement).ComboBox;

if (comboBox != null)

{

comboBox.ItemsSource = null;

if (string.IsNullOrEmpty(countryId) == false)

comboBox.ItemsSource = from r in iGasContext.Context.Regions

where r.CountryId == countryId

select r;

else

comboBox.ItemsSource = iGasContext.Context.Regions;

}

Thanks

Binding data of a column to an array element

If I use the following binding expression in a GridViewDataColumn

DataMemberBinding="{Binding Path=Days[1]}"

("Days" is an Array like Days[10])

I get the following error in the Visual Studio debug output window:

A first chance exception of type 'System.ArgumentException' occurred in Telerik.Windows.Data.dll

and the filter menu button in the column header is missing and the sorting function doesn't work anymore.

If I wrap the array element in a porperty in the business object and use this for binding, everything is fine. What's going on here?

Thanks

How to get a reference to new PaneGroup

When you have a DocumentHost and you drag one of the documents to create a new PaneGroup (using the compass), RadDocking dynamically creates a new PaneGroup. What is the recommended way to get a reference to it when it is created? I would like to add an event handler and set some other properties. I'm not seeing an obvious way of doing this.

Also, then you have multiple PaneGroups, each has a SelectedPane property. Is there any way to determine which RadPane is actually the one that is currently selected/has the focus?

ShowDialog and MSN messenger

Why does a window opened with ShowDialog set my MSN to "busy"?

If I turn off "showme as 'BUsy' when i'm running a full-screen program or presentation settings are turned on" in messenger, that seems to fix it. Are modal dialogs secretly full-screen? or do they have some sort of presentation settings?

Programmatically adding columns with display and edit templates for different data types

I display a collection of items in a RadGridView, each having a collection of parameters of possibly different types.

It works quite nicely if I use the resource definitions below along with an identical definition for each of the parameter columns:

01.<t:RadGridView.Resources>

02. <DataTemplate DataType="{x:Type vm:AnalogParam}">

03. edit template definition....

04. </DataTemplate>

05. <DataTemplate DataType="{x:Type vm:DigitalParam}">

06. edit template definition....

07. </DataTemplate>

08. <DataTemplate DataType="{x:Type vm:DummyParam}">

09. edit template definition....

10. </DataTemplate>

11.

12. <DataTemplate DataType="{x:Type vm:AnalogParamDisplay}">
