hi,

i've been working out a module, and want to use a dropdownlist web control with code behind. but there is something wrong

when i run this code below, the dropdownlist shows the months list but when i select a month - for example "June" - then click the button, the label text always changed into "January"...

but

when i run the code independently - outside DNN module - it works fine.

Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.LoadMe.DropDownList1.Items.Clear()Dim months() As String = {"January", "February", "March", "April", "May", "June", "July"}Me.DropDownList1.DataSource = monthsMe.DropDownList1.DataBind()End SubProtected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.ClickMe.Label1.Text = Me.DropDownList1.SelectedItem.ValueEnd Sub

Private

In your Page_Load handler, only bind the drop-down list control when Page.IsPostback is false. Note that Page_Load always runs before your button handler code is called:

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

       If Not Page.IsPostBack Then
            DropDownList1.Items.Clear()
            Dim months() As String={"January", "February" . . . "December"}
            DropDownList1.DataBind()
       End If
End Sub
