PagingBulletedListExtender resets page



I have a BulletedList with LinkButton as DisplayType and a PagingBulletedListExtender inside a UpdatePanel.
I recently updated AjaxControlToolkit to the version 15.1, before that it was version 3.

However, after updating the control now resets the page when I click on a link.

For example I click on the page for letter "C" and after that I click on a name.
With version 3 the bulleted list would still contain all names starting with "C".
With version 15.1 it resets the page to first letter ("A" or some number).

The only thing I changed is the AjaxControlToolkit. Can someone verify this behavior and say
wether it's a bug or a feature?

Thank in advance and kind regards

Would you please provide both versions of your sample so we can research them?

The version where it worked was 3.0.20820.0
The version where it is not working is

Thanks for the quick reply!

By versions of a sample I meant a sample project with the BulletedList and corresponding layout.
Would you please attach these archived projects to this workitem?

Ah, I see, my bad.
Wouldn't it be sufficient if I just provide the sample with the newest version?
I mean, the behavior is kind of obvious and the question is wether it is intended.

I don't know what release AJAX Control Toolkit v3.0.20820.0 dll belongs to, so it will be more convenient to provide an old, non-upgraded version of the project, so that I can upgrade it to the latest version.

That is kind but not possible as I cannot publish the project.

I will try and build a minimal project that demonstrates the problem with the current release
of ajax.

sorry for the late reply.
I have a mini project demonstrating the problem, it's fairly simple:
Just put a BulletedList with some values inside an UpdatePanel,
add BulletListeExtender and a label showing the selected value.

Upload does not seem to work, so here is the code:

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="Test.aspx.vb" Inherits="BulletListTest.Test" %>
<%@ Register TagPrefix="cc1" Namespace="AjaxControlToolkit" Assembly="AjaxControlToolkit, Version=, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e" %>

<!DOCTYPE html>

<html xmlns="">
<head runat="server">
    <form id="form1" runat="server">
        <asp:ScriptManager runat="server" />
            <asp:UpdatePanel runat="server">
                    <asp:BulletedList ID="blTest" runat="server" OnClick="blTest_OnClick" DisplayMode="LinkButton" BulletStyle="Square">
                        <asp:ListItem Text="A" Value="A" />
                        <asp:ListItem Text="B" Value="B" />
                        <asp:ListItem Text="C" Value="C" />
                        <asp:ListItem Text="D" Value="D" />
                        <asp:ListItem Text="E" Value="E" />
                        <asp:ListItem Text="F" Value="F" />
                        <asp:ListItem Text="G" Value="G" />
                        <asp:ListItem Text="H" Value="H" />
                    <cc1:PagingBulletedListExtender ID="blTest_PagingBulletedListExtender"
                        runat="server" ClientSort="True" Enabled="True"
                        SelectIndexCssClass="lbStandardTV" TargetControlID="blTest"
                        UnselectIndexCssClass="lbStandardTV" />

                    <asp:Label runat="server" Text="Selected value: " />
                    <asp:Label runat="server" ID="lblTest" />

Public Class Test
    Inherits System.Web.UI.Page

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

    End Sub

    Protected Sub blTest_OnClick(sender As Object, e As BulletedListEventArgs)
        lblTest.Text = blTest.Items(e.Index).Value
End Sub
End Class
The webform shows the behavior described above.
Can you verify that?

Kind regards
