    Hi is it possible to have the Initiator a particular Tab in a Tab Strip and its respective PageView as target Updated Control?
    In the Configurator, I only see an index type name like i0, i1, i2 under my TabStrip Control... So I tried to select it as I though ti twould but got the following error

    at Telerik.Web.UI.RadPageViewCollection.AddAt(Int32 index, Control child) at Telerik.Web.UI.RadAjaxControl.MoveUpdatePanel(Control initiator, Control updated) at Telerik.Web.UI.RadAjaxControl.PerformRender() at Telerik.Web.UI.RadAjaxControl.OnPageRender(HtmlTextWriter writer, Control page) at Telerik.Web.UI.RadAjaxControl.RenderPageInAjaxMode(HtmlTextWriter writer, Control page) at System.Web.UI.Control.RenderChildrenInternal(HtmlTextWriter writer, ICollection children) at System.Web.UI.Control.RenderChildren(HtmlTextWriter writer) at System.Web.UI.Page.Render(HtmlTextWriter writer) at System.Web.UI.Control.RenderControlInternal(HtmlTextWriter writer, ControlAdapter adapter) at System.Web.UI.Control.RenderControl(HtmlTextWriter writer, ControlAdapter adapter) at System.Web.UI.Control.RenderControl(HtmlTextWriter writer) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

    <telerik:RadTabStrip ID="tsCRMPPSA" runat="server" MultiPageID="mpCRMPPSA" SelectedIndex="0"
            <telerik:RadTab runat="server" Text="Search PPSA" PageViewID="pvSearch" Selected="True">
            <telerik:RadTab runat="server" Text="Register" PageViewID="pvRegister">
            <telerik:RadTab runat="server" Text="Results" PageViewID="pvResults">
    <telerik:RadMultiPage ID="mpCRMPPSA" runat="server" SelectedIndex="0">
        <%---------------------- Search Pageview ---------------------------%>
        <telerik:RadPageView ID="pvSearch" runat="server">
        <%---------------------- Registration Pageview ---------------------------%>
        <telerik:RadPageView ID="pvRegister" runat="server">
        <%---------------------- Results Pageview ---------------------------%>
        <telerik:RadPageView ID="pvResults" runat="server" EnableViewState="false">

    I've tried different combination without success:
    1. Actual Index of the Tab  as initiator and pvSearch, pvRegister , pv Result as Updated Controls
    2. tsCRMPPSA as Initiator and pvSearch, pvRegister , pv Result as Updated Controls

    The only combination that works is I used the top level
    tsCRMPPSA to update mpCRMPPSA .... so the whole multiplage is transferred as opposed to controls of the individual tab selcted.

    Also there is a bug in the COnfigurator... When you select the indexed ta b i0, i2, i3... closed it and you try to open the configurator again to do another change, the Ajax Settings are duplicated...

    Hello Gotcha,

    This is not possible, you cannot ajaxify particular Tab or PageView. You should ajaxify the whole RadTabStrip and MultiPage. And to optimiza the performance in this case, you should set AutoPostBack for the RadTabStrip and RenderSelectedPageOnly for the RadMultiPage to true.
