The RowUpdating event does pass the current row in the e.RowIndex property, so your code is correct for getting a reference to the DataRow being updated.

That will work if you want to store an empty date value rather than null...if you want to save a null instead, you should do this:

set { this.Row["svd_PostDT"] = (value == null) ? DBNull.Value : value; }
