Javascript error on clicking a link in a datalist

[Drew Mace]

We are getting this error when someone clicks on the asp:hyperlink in the datalist below:

this.get_linkElement() is null

<telerik:RadPanelBar ID="pbarUsersGroups" runat="server" Skin="WebBlue" AllowCollapseAllItems="True" CausesValidation="False"
           PersistStateInCookie="True"  >
                <collapseanimation duration="100" type="Linear" />
                    <telerik:RadPanelItem runat="server" Text="Online Users" PostBack="False">
                        <Items>
                            <telerik:RadPanelItem>
                                <ItemTemplate>
                                    <asp:DataList ID="dlOnlineUsers" runat="server" Width="100%" CellPadding="0" CellSpacing="0">
                                        <ItemTemplate>
                                            <asp:HyperLink ID="lnkOpenChatWindow" NavigateUrl='<%# "javascript:openChatWindow(false, \"" + Eval("Bare") + "\");" %>' runat="server" CssClass="rpLink">
                                                <span class="onlineUser"><%# Eval("User") %></span>
                                            </asp:HyperLink>
                                        </ItemTemplate>
                                    </asp:DataList>
                                </ItemTemplate>
                            </telerik:RadPanelItem>
                        </Items>
                 </telerik:RadPanelItem>
                <expandanimation duration="100" type="Linear" />
            </telerik:RadPanelBar>


Can anyone shed some light on why our users would be consistently getting this error when they click on the link?

Thanks

Hi Drew,

This error occurs because of the "rpLink" cssClass which is set to the asp:HyperLink, it's confused with the item's anchor tag.
