Hi Telerik

Again required your help….

I am using radrataform. I am not using auto-generating column.  I have two Textbox. One is Autocomplete and second is Textbox.

Now my requirement is when autocomplete focus is lost I have to perform one operation like…

 I am entering city name in Autocomplete box then second textbox zip code should automatically fill (through service).

Now my Issue is I am not able to getting lost focus event of my autocomplete textbox in my View Model.

 Here I attached screen of my xaml.

<telerik:RadDataForm   Width="600" Grid.Row="1" VerticalAlignment="Top"
                                x:Name="myRadDataForm"
                                Header="Data"
                                                    
                                                    
                                ItemsSource="{Binding Product }"                                       
                                          AutoGenerateFields="False"
                           ReadOnlyTemplate="{StaticResource MyTemplate}"
                           EditTemplate="{StaticResource MyTemplate}"
                           NewItemTemplate="{StaticResource MyTemplate}">
                            </telerik:RadDataForm>
 
 
<Grid.RowDefinitions>
                                <RowDefinition></RowDefinition>
                                <RowDefinition></RowDefinition>
 
                            </Grid.RowDefinitions>
 
                            <Grid.Resources>
 
                                <DataTemplate x:Key="MyTemplate">
                                    <Grid>
                                        <Grid.RowDefinitions>
                                            <RowDefinition></RowDefinition>
                                            <RowDefinition></RowDefinition>
                                        </Grid.RowDefinitions>
                                        <Grid.ColumnDefinitions>
                                            <ColumnDefinition></ColumnDefinition>
                                            <ColumnDefinition></ColumnDefinition>
                                            <ColumnDefinition></ColumnDefinition>
 
                                        </Grid.ColumnDefinitions>
 
 
 
                                        <TextBlock Text="Barcode" Grid.Row="0" Grid.Column="0" >
                                        </TextBlock>
                                        <syncControls:AutoCompleteBox  x:Name="autBarcode"  Text="{Binding Barcode, Mode=TwoWay}" Grid.Row="0" Grid.Column="1">

MyRadDataForm.CurrentItemChanged += new EventHandler<EventArgs>(MyRadDataForm_CurrentItemChanged);

void MyRadDataForm_ValidatingItem(object sender, CancelEventArgs e)

           TextBox k = sender as TextBox;
           if (k != null)

               string d = k.Name;
               string r = k.Text;
           }
 
       }

           if ((sender as RadDataForm).IsItemChanged)
           {
