Hi. I have some trouble.
Briefly...
I'm using:
- Silverlight
- MVVM
- RIA
- RadGridView (2010.2.0714 (July 14, 2010))
- Editing entity in Modal Dialog (RadWindow)
- Modal Dialog content is DataForm (Silverlight toolkit)
Grid XAML:


...
xmlns:grid="clr-namespace:Bridge.Helpers.Grid"
xmlns:clb="clr-namespace:Calabonga.Silverlight.Framework;assembly=Calabonga.Silverlight.Framework"



...

<

telerik:RadGridView Grid.Row="1"

EnableColumnVirtualization="True"

EnableRowVirtualization="True"

ActionOnLostFocus="CancelEdit"

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

ItemsSource="{Binding ElementName=Source, Path=Data}"

grid:RadGridViewHelper.ColumnsCollection="{Binding Path=ColumnsCollection}"

AutoGenerateColumns="False">

<i:Interaction.Triggers>

<i:EventTrigger EventName="Deleting">

<clb:EventToCommand Command="{Binding Path=DeleteEntityCommand}"

IsSendEventArgsToCommand="True" />

</i:EventTrigger>

<i:EventTrigger EventName="RowActivated">

<clb:EventToCommand Command="{Binding Path=EditEntityCommand}"

IsSendEventArgsToCommand="True" />

</i:EventTrigger>

<i:EventTrigger EventName="AddingNewDataItem">

<clb:EventToCommand Command="{Binding Path=AddEntityCommand}"

IsSendEventArgsToCommand="True" />

</i:EventTrigger>

<i:EventTrigger EventName="Filtering">

<clb:EventToCommand Command="{Binding Path=FilteringCommand}"

IsSendEventArgsToCommand="True" />

<clb:EventToCommand Command="{Binding Path=UpdateDDSFilterCommand}"

CommandParameter="{Binding ElementName=Source}" />

</i:EventTrigger>

</i:Interaction.Triggers>

</telerik:RadGridView>

MVVM method EditEntityCommand:

ModalDialogWorker mdw = new ModalDialogWorker();

RadWindow dialog = new ExtendedRadWindow();

IModalView view = new PersonDialogModalView();

dialog.Header = ApplicationStrings.DialogEditingTitle;

Person person = (Person)this.SelectedItem;

GridViewCell grid = ((GridViewCell)e.OriginalSource);

ModalViewContext<Person> cntx = new ModalViewContext<Person>(Dictionary.List, person, new PersonViewModel());

mdw.ShowDialog(dialog, view, cntx, p =>

{

if (dialog.DialogResult.HasValue && dialog.DialogResult.Value)

{

this.BridgeContext.SubmitChanges();

}

else

{

this.BridgeContext.RejectChanges();

}

});

remark: this.BridgeContext = DomainContext (RIA)

Everything work fine, BUT!!!
If I make error in DataForm, I'll see the red validation mark (and in gridview too), that is ok. But when I click Cancel button on ModalDialog, the dialog will closed and this.BridgeContext.RejectChanges. But the gridview stay marked error (see attached images), however, DomainContext has no errors.

Help to fine solution!!! PLEASE!!!
