After changing my ListBox to a DropDownList I noticed another issue and it could just be me so forgive me if I'm just doing it wrong but here goes.

Ok so I have a CustomControl this control is made up of several Panels of which some are hidden and others are not based on the users progress through the questionnaire.

Markup Snippet:

 <asp:Label ID="Sec1Q8Label" resourcekey="Sec1Q8Label" runat="server" />
 <asp:DropDownList ID="Sec1Q8"  OnSelectedIndexChanged="Sec1Q8SelectChanged" runat="server" Rows="1" CausesValidation="false" AutoPostBack="true">
  <asp:ListItem resourcekey="Sec1Q8Option0" />
  <asp:ListItem resourcekey="Sec1Q8Option1" />
  <asp:ListItem resourcekey="Sec1Q8Option2" />
  <asp:ListItem resourcekey="Sec1Q8Option3" />
  <asp:ListItem resourcekey="Sec1Q8Option4" />
  <asp:ListItem resourcekey="Sec1Q8Option5" />
  <asp:ListItem resourcekey="Sec1Q8Option6" />
  <asp:ListItem resourcekey="Sec1Q8Option7" /> 
 </asp:DropDownList>

 <asp:Label ID="Sec1Q8OtherLabel" resourcekey="Sec1Q8OtherLabel" runat="server" Visible="false" />
 <asp:TextBox ID="Sec1Q8Other" resourcekey="Sec1Q8Other" runat="server" Visible="false" />

Code Snippet:

        protected void Sec1Q8SelectChanged(object sender, EventArgs e)
        {
            if (((DropDownList)sender).SelectedIndex == 7)
            {
                Sec1Q8OtherLabel.Visible = true;
                Sec1Q8Other.Visible = true;

            }
            else
            {
                Sec1Q8OtherLabel.Visible = false;
                Sec1Q8Other.Visible = false;
            }
        }

Now the problem is this in the PostBack the DropDownList appears to be rebuild from scratch nulling out the selection. The same is true for RadioButtonList, I haven't tested any other than standard TextBox which is NOT regenerated and DOES retain its inputted value. I know this control works in a normal web form environment but prehaps I have got in over my head as far as understanding how DNN is implementing the web form.

Any information would be great.

Thanks again,

Josh

PS.

I did report the enhancement you wanted me to do Sebastian

Hi Josh,

Is SelectedIndex Null, -1, or 0?  Try assigning some unique values to your ListItem's

Thanks,
Mike

Mike is on the right track - without each ListItem having a unique value, the ASP.Net's determination of the selected item will always return the first matching, that is, the first item in the list.  In the control localization method in DotNetNuke.Framework.PageBase the following sets each ListItems Text property but does nothing to set the Value property:

If Not key Is Nothing Then
      Dim value As String = Services.Localization.Localization.GetString(key, ResourceFileRoot)
      If value <> "" Then
           ctrl.Items(i).Text = value
      End If
End If

Although you might want to add another bug report to Gemini for this, I'm not sure I would want to add any extra processing steps list control localization as most developers will provide a unique value to each list item as part of the markup. Try assigning a unique value (i.e. 0, 1, 2, 3 . . .) to each ListItem and let us know what happens.
