Preserving field values using with DetailsView_ItemInserted

[rlueneberg]

I am having difficulty with preserving field values in a DetailsView
control after clicking the insert button event.
protected void DetailsView1_ItemInserted(object sender,
DetailsViewInsertedEventArgs e)
{
e.KeepInInsertMode = true;
GridView1.DataBind();
}

What I noticed is if I click in a button outside DetailsView it does
preserve the values. My question is if is there any way to reproduce
the previous behavior without having to programatically restore the
control state values. Or maybe override the parte where the values are
being cleaned.

The reason I ask that is because I over 50 controls (template and
bound) and it will be a pain to recreate the state of these controls
manually.

Thanks
