Storing values without using Session var.

After the page loads and the 2 strings "rbid" and "rbmt" are validated, I want to "store"
them to be used later and then inserted into the database when Submit is clicked.
(I want these values to persist over any amount of time so using a Session variable won't work)
With VB, I used a Property.

What is the Object Oriented Programming approach (or the best way) in C# to do this?
If you have code examples, that would be great. Thanks

public partial class joinssl : System.Web.UI.Page
{

protected void Page_Load(object sender, EventArgs e)
{
string rbid = Request.QueryString["rbid"];
string rbmt = Request.QueryString["rbmt"];
// need to insert those values into the Database later, but don't want to
// rely on using Request.QueryString[] when the insertion occurs

Are you just wanting to make them be variables that are usable throughout the entire class instead of just in the page_load method? if so, do this:

public partial class joinssl : System.Web.UI.Page
{
//define some "global-class" variables that can be used anywhere inside this page
private string rbid = "";
private string rbmt = "";

protected void Page_Load(object sender, EventArgs e)
{
rbid = Request.QueryString["rbid"];
rbmt = Request.QueryString["rbmt"];
// need to insert those values into the Database later, but don't want to
// rely on using Request.QueryString[] when the insertion occurs
}

private void someMethod() {
//now in here you can use them again as needed
string blah = rbmt; //this value was set in the page_load method
}

thanks Bob . .
what syntax do I use to retrieve the value later in the code, ex:

ViewState["rbid"] = Request.QueryString["rbid"];
...

CreateProduct(newName.Text, ViewState["rbid"], . .

Bob Learned

CreateProduct(newName.Text, ViewState["rbid"].ToString(),

or

CreateProduct(newName.Text, (int)ViewState["rbid"],

depending on the data type stored.

Looking back at some VB code, I was actually doing the same thing
with the viewstate using a Property:

Private Property CustomerID() As Integer
Get
Dim value As Integer = 0
If Not ViewState("CustomerID") Is Nothing Then
value = DirectCast(ViewState("CustomerID"), Integer)
End If
Return value
End Get
Set(ByVal value As Integer)
ViewState("CustomerID") = value
End Set
End Property

Is it better to use a Property or does it not matter?

I love the idea of using properties, but only if they need to be public.
