  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.
