Hi I am using Autocomplete box inside Grid view.
I can use Autocompletecompbox but my requirement is different. Now I can also use GridviewData Column but I want to set My focus fix in my Autocomplete box till data loading or data validating. Here I am attaching my xaml file and .cs file I am not able to attached project here so I cannot attaching.
In Conclusion issue is when add new row focus going back of first cell, it should go in Autocompletebox.
