Hi,
(Using ASP.Net 2.0)
I have a wizard control inside a detailsview control. When I attempt
to call the InsertItem method on the DetailsView I get an error
"ObjectDataSource 'ObjectDataSource1' has no values to insert. Check
that the 'values' dictionary contains values."
I have found I can suppress the error by placing a hidden field inside
the DetailsView, but outside the Wizard control. This hidden field
must be bound to the DetailsView dataitem. The only problem with this
is that the two-way databinding is broken.
This behaviour seems very similar to that in bug FDBK27772,
http://lab.msdn.microsoft.com/Produc...1-7e93b1d52077
I was going to submit this to Microsoft, but I thought I'd try here
first.
Thanks,
Chris Needham
Sample code below...
In app_code...
public class Animal
{
public Animal()
{
}
private int id;
public int Id
{
get { return id; }
set { id = value; }
}
private string description;
public string Description
{
get { return description; }
set { description = value; }
}
}
public class AnimalBL
{
public AnimalBL() { }
public void Insert(Animal newAnimal) { }
public Animal Select()
{
return new Animal();
}
}
