I have a Textbox control inside a listbox under  DataTemplate where I am adding dynamically.
I am checking in the collection whether TextBox is empty or not, if Empty then I am displaying message.
But I want to set the focus to that control  where the textbox is empty.

inside the code where you display the message add in code to set the focus to the textbox.

assuming an event is triggered for the textbox when the text box is to get focus you'd use add this line of code inside the if statement displaying the message:
//if textbox is empty do this:
{
  //... code to display your message
  (TextBox)sender.IsTabStop = True;
  (TextBox)sender.Focus();
}

I have found the solution

below will be the code
 TextBox txt = sender as TextBox;
            Collection client= txt.DataContext as Collection;
            if (string.IsNullOrEmpty(client.Code))
            {
                lstbox.ScrollIntoView(client);
                txt.Focus();
            }
