passing session variable from DDL

[kai]

Hi, All
I put Drop Down List on a ASP.NET form, it contains "CustomerID" from
Northwind Database from SQL Server 2000 "Customers" table. I use
SqlDataAdapter, SqlConnection and DataSet control to connect the
"ddlCustomerID" control. When I select a customerID from the list, let say
"BLONP",
and navigate to next page, it always point to first item on the list
"ALFKI". This is my code on "btnNext_Click" event:

Session("customerID")=ddlCustomerID.SelectedItem.Value
Me.Response.Redirect("next.aspx")

On next.aspx page, I have Session("customerID")="ALFKI" all time. What is my
problem?

Thanks

Kai

Kai,

My immediate guess is that you are rebinding the drop down on every post
back.

If this is the case that means that you need to use code like this:

If Not IsPostBack Then
'---Bind your drop down list here
End If

What is happening is that, when the page is loaded, you are rebinding the
drop down. That resets it's selected item to the first item in the list.
