Hello,

I am creating a table has follows:

create table dbo.Tags
(
    TagID uniqueidentifier not null
        default NewID()
     constraint PK_Tag primary key clustered,
    TagText nvarchar(100) not null
)

I am using a LinqDataSource and a ListView to create records in this
table. I am able to delete and update records but when I insert a
record I get the error:

Violation of PRIMARY KEY constraint 'PK_Tag'. Cannot insert duplicate
key in object 'dbo.Tags'. The statement has been terminated.

In fact I am able to insert ONE record and its ID becomes:
00000000-0000-0000-0000-000000000000

So when I insert a second one, I suppose, the ID is 000... again and
this is why I get the error ...

What am I doing wrong?

Thanks,
Miguel
