Hi everyone.

I actually try to understand how Ajax Tookit Tabs control works.

In one of my tab, I will load a lot of pictures, and I guess that if I put all the pics directly in a TabPanel, it will load all the pics at start.

What I would, is to load the pics ONLY when I click on the tabs called "Pictures".

I've looked a while for doing this, bug It still not working.

My aspx page is : 

<cc1:TabContainer ID="TabContainer1" runat="server" ActiveTabIndex="0" OnClientActiveTabChanged="clientActiveTabChanged">
            <cc1:TabPanel HeaderText="tab1" runat="server">
                <ContentTemplate>
                    <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
                        <ContentTemplate>
                        yeah ?
                        </ContentTemplate>
                    </asp:UpdatePanel>
                </ContentTemplate>
            </cc1:TabPanel>
            <cc1:TabPanel HeaderText="tab2" runat="server">
                <ContentTemplate>
                    <asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional">>
                        <ContentTemplate>
                            Photos...
                        </ContentTemplate>
                    </asp:UpdatePanel>
                </ContentTemplate>
            </cc1:TabPanel>
        </cc1:TabContainer>

 I find a Javascript source to do that :

        function RefreshUpdPanels() {
            var index = $find('TabContainer1').get_activeTabIndex();
            if (index == 0) {
                __doPostBack('UpdatePanel1', '');
            } else if (index == 1) {
                __doPostBack('UpdatePanel2', '');
            }
        }

And it doesn't work T_T When I click on the 2nd tab, I think a "postback" is realized and It turn back to the tab1. How to do a "loading" like in this forum (with a "loading..." animation, etc...)

 Thank you !
