I am a beginner to ASP.Net Web Pages using razor. Trying to build a site for the first time.... I need some help regarding String format was incorrect while updating/inserting Image details:
fileTitle = Path.GetFileNameWithoutExtension(photo.FileName).Trim() ;
fileExtension = Path.GetExtension(photo.FileName).Trim();
-------------------------------------------------------------------------------

Any assistence in above code to check whether it is optimized or not efficient is welcomed
I m not a pro nor intermediate.. just modifying the templates from webmatrix...
One more thing, currOrg does not enter any value into database... it shows blank field even though Update/Insert commands work!
