Default Chapter 12: p. 410 Try It Out - DetailsView Control

Hi Imar,

First of all - excellent book, I'm really enjoying learning ASP.NET 3.5!

I've run into a problem with the Try It Out starting on page 410 (Managing Data with the DetailsView Control). I have followed all of the steps (I believe to the letter) four separate times, and every time I run the code I get the error:

"The version of SQL Server in use does not support datatype 'date'."

with the following stack trace:

Code:
[ArgumentException: The version of SQL Server in use does not support datatype 'date'.]

Any help would be greatly appreciated!

Not sure if this is where you're having your problem, but the data type for the CreateDateTime and the UpdateDateTime fields is supposed to be "datetime" not just date (p375).

In my AddEditReview.aspx I have:
Code:
<asp:Parameter Name="UpdateDateTime" Type="DateTime" />
in the UpdateParameters and InsertParameters section - as opposed to what you have:
Code:
<asp:Parameter DbType="Date" Name="UpdateDateTime" />
It could be there's a mismatch of data type which is causing the error...

Hope this helps...

Hi Hans,

Good to hear you like the book so much.

The issue you came across is listed in the errata section of the book: http://www.wrox.com/WileyCDA/WroxTit...Cd-ERRATA.html

It's caused by a change in VWD where a DateTime is inferred as a Date. As cbspira indicated, changing Date to DateTime should fix the problem.

Cheers,

Imar
