File Upload Button

[rjmiller]

I still have issues with the file upload button.  It does it job with regards to the uploading of files very well.  The issues I have is with processing before and after.

I have a button on a netwebform that uploads a file.  It is associated with a file column that stores it's filename.  After placing _traces in various places I have managed to get all associated processing done on upload.  My problem is that on deletion of the file I need to clear the field of its filename (assign ''' to it).  I cannot find a way to do this.  I have done gsv's at MANY locations and it would appear that even without clicking on the file upload button some type of processing occurs that results in the saving of the field after I have cleared this field.

Where does processing take place for the file upload on exit from the form?  Is there some way to associate the file upload button with a local field?  I have tried this but without much success.

I am obviously missing something.

Thanks for any help...
