I&#039;m loving the &#039;Extensive Examination of the Data Grid&#039; articles but have a question about the Master/Detail grid in Part 14. On the View Live Demo at this address:<BR><BR>http://aspnet.4guysfromrolla.com/demos/MasterDetail.aspx<BR><BR>the FAQCategoryID appears in the "nested" grid, even though it is not desirable to have it appear (at least in my implementation). I&#039;m assuming it is necessary to be able to apply the filter, and that there&#039;s nothing that can be done to make it invisible. If there is a way to make it invisible, please let me know. Thanks.
