I'm using Firebird 2.5 and the .net provider with an asp.net web application. Data is provided by an EntityDataSource backed by an EDM generated from a firebird database. I can load a type 0 blob field with image data by handling the DetailsView ItemUpdating event.
protected void DetailsView1_ItemUpdating(object sender, DetailsViewUpdateEventArgs e) { ..... e.NewValues.Add("PHOTO", <image data as byte[]>); //PHOTO is a blob field } However, when I try something similar to delete the image data, nothing happens object value = (byte[])null; e.NewValues.Add("PHOTO", value); Can anyone explain how to put null into the blob field? pablo ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
