Ok, I figured it out. Default value for string size is 0, that's why empty strings were updated. I changed the size and now everything works fine :)

Hi, I have problem with updating string values using GridView. After pressing edit button i insert new values into textboxes. But after update, updated are only columns, which are not string. String values become empty. Im using Oracle database. Here is relevant code fragment: Can anyone help me please?

Hi I have the same problem. I spent a lot of time trying to fix this but without any success. I added some bounded and template fields to detailsview, witch may caused the problem. If you find a solution, can you please share it with me? Thanks
