using the FeatureDataRow.Fid. Like this:

FeatureDataRow featureDataRow =featureDataTable.NewRow();
featureDataTable.Rows.Add(featureDataRow);
.
.
int oid =featureDataRow.Fid;
.
.
AttachmentManager manager =featureDataTable.FeatureSource.AttachmentManager;
Attachment attachment=New Attachment(featureDataTable.FeatureSource, oid, fileName);
.

i try this. but i get this error. it means tha the id that you said is a temporary id so it doesnt work to create attachments, i need to make this work with only one form, i wouldnt like have to create the feature and then selected to add the file.

The code i showed to you is one of the project i did. It add the new feature and attachments if user choose to attach files. it woked for me. You are right on the sense that you has to create the feature in the featuresource so you can have an tempory id (actually it is a negitive number) in the map cache for you to add attachment. But you can definitely created the user experience through the code that user don't feel that way....
