Master/Detail problem on Whidbey CTP build

[Johnny §õ«¶¿« \(Microsoft MVP for ASP.NET\)]

The following code is from the online tutorial but it doesn't run on my CTP
build I've just installed.

The first problem is, ImageField doesn't have a public DataField field. Ok,
I removed this line.

The second problem is that "the @EmployeeID column can not be found." Hmmm,
could any one help me verify if the program happens on your side?

BTW, I didn't install SQL 2005. I still use SQL 2000. Can it be the cause of
the problems?

<table cellpadding="10">

<td valign="top">
<asp:GridView

DataSourceID="MasterSource"

<asp:TemplateField HeaderText="Employee">

Haaa! I found the solution by myself from the MSDN product feedback center.

There is a syntax change in the new version, just change

FilterExpression="EmployeeID='@Employee'"

to

FilterExpression="EmployeeID='{0}'"

and the problem is gone.
