FormView update problem

[jphaycock]

I've been trying to do this all day.

Sorry if the lingo isn't right but I think this is close:

I have a formview that is using an ObectDataSource to bind to a class
in my app_code folder. I have an update method in that class that
works fine. and I am using this as the formViews update method. There
are just 4 fields

ID int
Name string
Description string
added boolean

The ID is taken from a dropdownList (selectedValue). When I choose an
item from the dropdown the formview is populated. I can add and delete
items in the form view but when i do an update it complains that the
ID column is read only.

I have used this check in the ItemUpdating event to check the value of
the id and it is null

Label skillID = FormView2.FindControl("Id") as Label;
if (skillID != null)
{
e.NewValues["Id"] = skillID.Text;
}
else
{
//get annoyed!!
}

I have no idea why it is getting set to null.

Has anyone got any ideas? Any help is much appreciated I have Googled
it to death but got nowhere

Can anyone help me with this it's driving me nuts.

It was easier to use the old datagrids!!!

I have tried doing this in the FormView_ItemUpdating method:

Label labelID = (Label)FormView2.FindControl("IdLabel1");
string myID = labelID.Text;
if (myID != null)
{

e.NewValues["Id"] = Convert.ToInt32(myID);
}

but it wont perform the update it complains that the column Id is read
only. It should be read only shouldn't it? It's a primary key.

I have set the DataKeyNames propery to "Id" so I can't understand what
is going wrong.

Thanks in advance
