DetailsView gives a blank page on update

My problem is that when i press the update button on a detailsview i
get a blank page with no events being called. Not even page_load gets
called, nor does an exception get thrown. In the detailsview i have
autogenerateedit enabled and it does switch modes but no update. Im
using a tableadabter with all the insert/update/delete methods. So im
asking if anybody else has had this problem and how do i fix it.

code below

in cs file

protected void DetailsView1_ItemUpdating(object sender,
DetailsViewUpdateEventArgs e)
{
//never gets called by the update button
e.Cancel = false;
}

protected void DetailsView1_ItemUpdated(object sender,
DetailsViewUpdatedEventArgs e)
{
//never gets called by the update button
if (e.Exception != null)
{
//notifiy user

}
}

in aspx
