Ok finally think I have found the difference, sorry about the delay.
In the C# version of the book it reads:
6) Create an event procedure for the
Updated event of the
Details data source, by selecting the
DetailsDataSource control and double-clicking into the
Updated event when viewing the events in the properties page.
I think (do not quote me on this) that they are referring to this bit of the code, which you can see in the END folder of the C# version:
Code:
protected void DetailsDataSource_Updated(object sender, System.Web.UI.WebControls.SqlDataSourceStatusEventArgs e)
{
GridView1.DataBind();
}
This is the line that directly refers to the
Updated method. I also have the same issue with the drop down list, however it is interesting in that the C# version does not refer to it at all in the TRY IT OUT, may be itâs something to do with the build of Studio the book was written using. If my mind served me correctly then the C# version was done with a Beta perhaps it has changed in the final release.
To be truthful however, I code everything straight by hand, very rarely using a control so I have never noticed that quirk before.
Good luck, I hope that this solves your problem.
