    I have a RadGrid headercontextmenu enabled and resizing and moving of columns set to true.
    When I show the grid these functions are working correct. When I switch to another page of the grid the contextmenu does not appear and I can't move of resize a column.
    How can I solve this problem?

    <telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="EntityDataSourceChangeLog"
        AllowPaging="True" AllowSorting="True" GridLines="None" CellSpacing="0" EnableHeaderContextMenu="True"
        AllowFilteringByColumn="True" EnableHeaderContextFilterMenu="True" AutoGenerateColumns="False"
        OnItemCommand="RadGrid1_ItemCommand" Width="100%">
        <MasterTableView DataSourceID="EntityDataSourceChangeLog" IsFilterItemExpanded="false"
            DataKeyNames="LogId" UseAllDataFields="True">
                <telerik:GridBoundColumn DataField="ProjectName" HeaderText="Project" SortExpression="ProjectName"
                <telerik:GridBoundColumn DataField="UserName" HeaderText="User" SortExpression="UserName"
                <telerik:GridBoundColumn DataField="LogMessage" HeaderText="Log Message" SortExpression="LogMessage"
                <telerik:GridBoundColumn DataField="LogTime" HeaderText="DateTime" SortExpression="LogTime"
            <PagerStyle AlwaysVisible="True"></PagerStyle>
        <ClientSettings AllowColumnsReorder="true" ReorderColumnsOnClient="true" ColumnsReorderMethod="Reorder">
            <Scrolling UseStaticHeaders="true" AllowScroll="false" />
            <Animation AllowColumnReorderAnimation="false" />
            <Resizing AllowColumnResize="true" AllowResizeToFit="true" EnableRealTimeResize="true"
                ResizeGridOnColumnResize="true" />
        <PagerStyle AlwaysVisible="true" Mode="NextPrevAndNumeric" />
        <FilterMenu EnableTheming="true">
            <CollapseAnimation Duration="200" Type="InOutQuint" />
        <ExportSettings ExportOnlyData="true" IgnorePaging="true" OpenInNewWindow="true"
            FileName="FlightMapChangelogExport" Excel-Format="ExcelML">
            <Excel Format="ExcelML"></Excel>

    I have added the grid to UpdatedControls of RadAjaxManager:

    <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
                <telerik:AjaxSetting AjaxControlID="RadGrid1">
                        <telerik:AjaxUpdatedControl ControlID="RadGrid1" />

    When I delete this the contextmenu and the reordering/resizing of columns works normally when I switch between pages in the grid.
    Why is this not working when addeing the grid to the UpdateControls?

    I have solved the problem.
    I had the grid in a usercontrol. The RadAjaxManager was also in that usercontrol.
    When I moved the RadAjaxManager to the form where the usercontrol was called from the contextmenu is working correctly.
