I am having a problem cahnging default mode in the code.What i am trying to
do is: on page load event:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
Handles Me.Load

If Page.IsPostBack Then

itemview.DefaultMode = DetailsViewMode.ReadOnly

Else

itemview.DefaultMode = DetailsViewMode.Insert

End If

End Sub

doesn't change the mode on detailsview.

ANY HELP PLEASE
 
Try moving that code to Page_Init. I think the viewstate is being saved
before you make that change, so it doesn't push through to the output.
