How to disable the page refresh due to activeTabChange of TabContainer inside UpdatePanel?

[mittalpa]

Hi I am using AJAX TabContainer control with following settings. When I change a tab the postback happens and whole page refreshes. Because AutoPostBack="true"> . To AJAxify the behavior, I added UpdatePanel around it but still the page is refreshing. The control need to go to server because user controls contains some grids which need to be populated. <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager> <asp:UpdatePanel ID="upTLTop" runat="server" UpdateMode="Conditional"> <ContentTemplate> <AjaxCT:TabContainer ID="tcProducts" runat="server" ActiveTabIndex="0" Style="height: 100%; vertical-align: top; margin: 0px; padding: 0px;" OnActiveTabChanged="Products_OnActiveTabChanged" AutoPostBack="true"> <AjaxCT:TabPanel runat="server" HeaderText="MBS" ID="pnlMBS"> <ContentTemplate> <uc1:ucA ID="ucA1" runat="server" /> </ContentTemplate> </AjaxCT:TabPanel> <AjaxCT:TabPanel runat="server" HeaderText="ABS" ID="TabPanel1"> <ContentTemplate> <uc2:ucB ID="ucB1" runat="server" /> </ContentTemplate> </AjaxCT:TabPanel> </AjaxCT:TabContainer> </ContentTemplate> </asp:UpdatePanel> How can I disable the page refresh and at the same time server side operation happens in this case? Please advise. Thanks AJ
