Viewstate ...

[Borry]

Hello everybody,


I'm already since a few day looking for my solution ...
I want to save a viewstate with a certain value. When the first autopostback occurs, then my viewstate isn't saved, the second postback then I have my viewstate but it's like one step behind.

Look at my following example. It's very simple.. it contains one dropdownlist which is on autopostback=true

Public Class WebForm2
    Inherits System.Web.UI.Page
    Protected WithEvents list1 As System.Web.UI.WebControls.DropDownList
 
    Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        'Put user code to initialize the page here
 
        If Not Page.IsPostBack Then
            list1.Items.Add("test")
            list1.Items.Add("test2")
        End If
 
        Response.Write(viewstate("test"))
 
    End Sub
 
    Private Sub list1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles list1.SelectedIndexChanged
 
        viewstate("test") = list1.SelectedItem.Text
 
    End Sub
End Class

When you select a value in the list, then the autopostback occurs. It doesn't give me a value. But when you choose a second value now, then the first value will be written on the page...

Please don't look at the selecteditem value that I pass through. I know this goes directly. It's just for TESTING purposes.
My final thought is that I have three or four dropdownlists and that I can know with the viewstate which combo has been used.
Example : combo1_selectedindexchanged gives viewstate("combo")="combo1"
combo2_selectedindexchanged gives viewstate("combo")="combo2"

Does anyone know a solution for my problem ?

Thanks in advance !
