asp.net 2010 vb formview

I have a formview that does an insert.  When user inserts a duplicate key, it errors out, how can I catch this?  Something like this?

formview1.itemInserting.......
label1.text = "Item already exists"
end sub

I just can seem to find the right event.

you might want to try FormView_ItemInserted event in which you can check EventArgs for proper information if the item has inserted or not.
here is some sample code:


protected void MyFormView_ItemInserted(object sender, FormViewInsertedEventArgs e)
{
      if (e.Exception != null)
      {
            // display exception
            lblException.Text = e.Exception.ToString();
            e.KeepInInsertMode = true;
            e.ExceptionHandled = true;
       }
}
