    You, my friend, are a genius.

    Nobody else on the interwebs even had a clue on how to achieve this little gem of a feature involving linq.

    Thank you so much!

      Thanks :)

      I have search the web for a solution because I knew (deep inside me) that something should exists…

      Found some sources and sample, then i made it from my own and ‘voila’…

      Happy that my experience bring you some help.
