RegisterHiddenF ield() Not Updating After PostBack

[Pete Mahoney]

I have a datagrid with a button column that displays some partner
info. i.e. PartnerId, PartnerName ... The button column has a button
that when the user clicks it they are redirected or server.transfer to
a different page where I would like to pass the PartnerId. I could do
this very easy with a QueryString, but would rather not display this
info in the URL. I want to pass this by creating a form variable
using the RegisterHiddenF ield() function.

i.e.
Private Sub PartnerGrid_Ite mCommand(ByVal source As Object, ByVal e As
System.Web.UI.W ebControls.Data GridCommandEven tArgs) Handles
PartnerGrid.Ite mCommand
RegisterHiddenF ield("PartnerID ", _
PartnerGrid.Dat aKeys(e.Item.It emIndex)
If e.CommandName.T oString() = "Preview" Then
'Server.Transfe r("Somewhere" )
End If
End Sub

Now the problem here is when I call the RegisterHiddenF ield() the page
is not Posted again before the Server.Transfer so the value of
"PartnerId" is never updated. How do I repost this page so this value
is updated before I Server.Transfer ?

Pete,

There is a better way.

If you add your value to the page context object it will be passed to the
new page on server.transfer .

Do so like this:

Context.Items.A dd("PartnerId" , e.Item.ItemInde x)

Server.Transfer ("Somewhere" )

'---Retrieve the value on the next page...
Dim ItemIndex As Int32 = CType(Context.I tems.Item("Part nerId"), Int32)
