Lost Focus event for textbox in raddataform.

[Amitkumar]

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"
