How to set the Selected.Index of an asp:DropDownList in ViewState?

[sa5cha]

Hi,

can someone help me ? I need to select the correct value of an ASPropdownList after an autopostback ?

The following wont work :

    Protected Sub ddl_printout_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs)
        
        ddl_printout.SelectedIndex = Session("Index_ddl_printout") 
        ddl_printout.DataBind()
        
        Tabs.ActiveTabIndex = 2
        Tabs.DataBind()
    End Sub



                <asp:DropDownList ID="ddl_printout" runat="server" DataSourceID="tb_printout" 
                    DataTextField="TB_PRNT_Longname" DataValueField="TB_PRNT_Index" 
                    Width="295px" OnSelectedIndexChanged="ddl_printout_SelectedIndexChanged" 
                    AutoPostBack="True">
                </asp:DropDownList>

Thank You Sascha

there are couple ways

ListItem item = DropDownList.Items.FindByValue("the value")
if(item != null) item.Selected = true;

ListItem item = DropDownList.Items.FindByValue("the value")
DropDownList.SelectedIndex = DropDownList.Items.IndexOf(item)

i'm sure they're are more too.
