public ObservableCollection<Employee> SofiaCarRentalDomainContextCollection
{
    get { return _productionDataCollection; }
    set
    {
        _productionDataCollection = value;
        RaisePropertyChanged("SofiaCarRentalDomainContextCollection");
        EnableCommands();
    }
}

 

<telerik:RadGridView x:Name="RadGridView1" ItemsSource="{Binding SofiaCarRentalDomainContextCollection}" MinHeight="100" MaxHeight="500" Width="600" Height="200"

I am also having same problem with 2012 Q3 sp1 release.
Do not know steps to invoke EndEdit event in MVVM ICOMMAND

<telerik:RadGridView x:Name="radGridview"
                            ItemsSource="{Binding AllItems}" SelectedItem="{Binding SelectedItem,Mode=TwoWay}" Grid.Row="0"
                              AutoGenerateColumns="True"
                            IsReadOnly="True" HorizontalContentAlignment="Stretch"
                            >
           <telerik:RadGridView.Columns>
               <telerik:GridViewToggleRowDetailsColumn>
               </telerik:GridViewToggleRowDetailsColumn>
           </telerik:RadGridView.Columns>
           <telerik:RadGridView.RowDetailsTemplate>
               <DataTemplate>
                   <telerik:RadDataForm Grid.Row="0"
                            Name="clubsForm" CurrentItem="{Binding}" Margin="5">
                       <i:Interaction.Triggers>
                           <i:EventTrigger EventName="EditEnded" >
                               <i:InvokeCommandAction Command="{Binding EditEndedCommand}"  CommandParameter="{Binding ElementName=clubsForm, Path=CurrentItem}" />
                           </i:EventTrigger>
                       </i:Interaction.Triggers>
                   </telerik:RadDataForm>
               </DataTemplate>
           </telerik:RadGridView.RowDetailsTemplate>
       </telerik:RadGridView>

Here EditEndedCommand is not hit in view model

Private _ic1 As ICommand
   Public ReadOnly Property EditEndedCommand As ICommand  ' System.Windows.Input.ICommand
       Get
           If _ic1 Is Nothing Then
               _ic1 = New RelayCommand(AddressOf EditEnded_Click)
           End If
           Return _ic1
       End Get
   End Property

please suggest..

Hello,

Can you please check whether you have any BIndingExpressionPath errors in your Output at runtime. In case the issue persists, I would kindly ask you to send us a repro project that we would be able to debug on our side and locate the issue.

All the best,
