No matter what I select my dropdownlist box is posting the value of the first option.

Here is the drop down box

 <asp:DropDownList ID="locationDropDown" runat="server"
           
           
            style="top: 300px; left: 400px; position: absolute; height: 13px; width: 139px"
            DataSourceID="ds" DataTextField="description"
            DataValueField="pkey"
         
        >
           
        </asp:DropDownList>


here is the event that is triggered and passes the value to the next page.
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs)
         Context.Items.Add("requestor", requestorTextBox.Text)
         Context.Items.Add("supplier", supplierTextBox.Text)
         Context.Items.Add("location", locationDropDown.SelectedValue)
         Context.Items.Add("csRep", csRepDropDown.SelectedValue)
         Server.Transfer("poResults.aspx")
         requestorLabel.Text = locationDropDown.SelectedValue
     End Sub

Here is the catching code on the page load event of the page sumitted to


 Label1.Text = Context.Items("csRep")

Are all of the dropdowns doing this...I noticed you had more than one, or just this one?

try AutoPostBack = true and see what happens...It will produce a refresh but I want to see if it will change then...

Yes both drop downs are doing it. I have already tried setting the auto post back property.  Also if I set an event of a change of the drop down it will not work either.

Where is the code that binds the dropdownlist? Is it on the Page_Load event? If so, make sure to put it inside an Not IsPostBack if condition
