If I ever had to add a property to my data object, the UI would automatically work.I wanted to set Default Mode to Edit and set Auto Generate Rows to true. Whether Auto Generate Rows is true or whether it is false and I use asp: Bound Field, if Default Mode is Edit then dvr. But if I am not creating a simple CRUD application and I want a separate button that does some action other than update, I must also create 20 template fields and 20 lines using Find Control.

But we need to set the proper command Name for them such as "Edit", "Update", "Cancel" ... =" | MIME-Version: 1.0 | Content-Type: text/plain; | charset="Utf-8" | Content-Transfer-Encoding: 7bit | X-Newsreader: Microsoft CDO for Windows 2000 | Content-Class: urn:content-classes:message | Importance: normal | Priority: normal | X-Mime OLE: Produced By Microsoft Mime OLE V6.00.3790.0 | Newsgroups: microsoft.public.dotnet.framework.aspnet | NNTP-Posting-Host: TK2MSFTNGXA03gbl 10.40.2.250 | Path: TK2MSFTNGXA01gbl!In addition to saving the developer from constructing a data object from a collection of new values, this would enable the developer to store the object in the session, which is not availble in the select and update methods of the data object.Also, it would permit a more intuitive UI because buttons would not have to be in the Detail View except when that makes sense.NET autogenerate | an update button, and then press update after making changes, but I don't | want that update button.

If Auto Generate Rows is true, then the order of the fields seems random and thus how could they be mapped to each dvr. This is still easier than a UI that uses no data binding at all, but it seems like it would have been pretty easy for MS to have eliminated the need to write and maintain these additional 40 lines of code.
