If it's data bound, why not saving from data source instead? Besides, one thing at a time. Learn reading from DataGridView (or, better, updating a data source and using data source, not the control) separately, memory string — separately. At least, explain where do you face a problem.

It's no different than any other implementation. The column gives you an Image object, usually a Bitmap, and you can use any of the thousands of examples all over the web.

Google for "c# convert image to byte array".

Yeh, I have searched the web since for days. I haven't found one example on how to save an image from an existing datagridviewImage cloumn to sql. everything is about saving an image either with filestream memorystream using opendialog

Take the one with MemoryStream. There are bytes in it.

Then you're really not understanding what the pieces of code do. You're NOT going to get a copy'n'paste solution to this. It's not that hard.

Every example starts with an Image or Bitmap (same thing really!) object, correct? You get that from your row in your data source that you bound the grid to.

Now they'll move on to setting up a MemoryStream object. Easy enough. Every implementation setups a Stream, be it a MemoryStream or FileStream, they are both Streams and work the exact same way. One just requires a filename, the other doesn't.
