I have a DVWP that is filtered by a query string parameter. When the user clicks on "Add New Item", I would like the column that the DVWP filters on to auto fill with the same value that the DVWP page is currently filering on. Also, I would like that column to be invisible so that the user cannot change it. I am not sure how to pass the query string value to NewForm.aspx when the user clicks on "Add New Item". Thank you for your help!
