server.transfer question

[wsyeager]

After using Server.Transfer to transfer data from one page to another, I would like to know if there is a way to keep the receiving web page variables intact after a postback.

 

Here is the code from the "sending" page:

<code>

Public ReadOnly Property SelectedDate() As Date

Get

Return Calendar1.SelectedDate

End Get

End Property

.

.

.

Server.Transfer("SignUp.aspx")

</code>

 

Here is the code in the receiving page:

<code>

Protected SelectedDate As Date

Public clsCalendar As Calendar

.

.

.

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

 

If Not IsPostBack Then

clsCalendar = CType(Context.Handler, Calendar)

SelectedDate = clsCalendar.SelectedDate

Session.Item("dteSelectedDAte") = CType(SelectedDate, Date)

End Sub

</code>

 

I am forced to place the property SelectedDate into a Session variable (Session.Item("dteSelectedDAte") = CType(SelectedDate, Date)

) because after the postback, I lose access to the receivning varaible (SelectedDate) which was transferred from the original page. Now, however, after a postback, the sending page is the same page, not the original.

 

It's no big deal. I would just like to know if this is the way it supposed to work...

You can use the Context.Handler without resorting to the session objects.

[wsyeager]

Yes, that's true, but after postback you lose reference to the Context.Handler, forcing you to place any of the variables in session state, etc.

 

Using the Context.Hanlder seems great for one time page usage on passing values to the receiving page.

Passing the variable to the receiving page via its query string would make the most sense. Session state really wasn't meant for such a use.
