ObjectDataSource and ReadOnly Object Property

[Guest]

LS,

I've an object who has an readonly property named Id, this property is
filled from the database with an Identity-value.

When I execute "DetailsView1.UpdateItem(true);" then I get the
following exception:

The 'Id' property on the type specified by the DataObjectTypeName
property in ObjectDataSource 'ObjectDataSource1' is readonly and its
value cannot be set.

I've tried al logical properties on the ObjectDataSource, but I can't
find an anwser.

Could somebody help me.

Thanx in advance.

Greetz,
