Answer 1

您必须添加RadAjaxManager和RadAjaxLoadingPanel

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="RadGrid1">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="RadGrid1" LoadingPanelID="RadAjaxLoadingPanel1" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManager>
<telerik:RadAjaxLoadingPanel runat="server" ID="RadAjaxLoadingPanel1"></telerik:RadAjaxLoadingPanel>
<div class="demo-container no-bg">
    <telerik:RadGrid RenderMode="Lightweight" ID="RadGrid1" runat="server" DataSourceID="SqlDataSource1" AllowSorting="True"
        AllowPaging="True" GridLines="None" Width="100%">
        <PagerStyle Mode="Slider" Position="TopAndBottom" PageSizeControlType="RadComboBox"></PagerStyle>
    </telerik:RadGrid>
