wheni run显示错误如下



ID为'updatepanel'的控件需要页面上的ScriptManager 。 ScriptManager必须出现在任何需要它的控件之前。



我的源页面有什么问题。



问候，

解决方案

您需要添加脚本管理器才能使用更新面板



添加以下

 <   asp：ScriptManager     ID  < span class =code-keyword> =  ScriptManager1    runat   =  server >  
 <   / asp：ScriptManager  >  

<块引用>为你的gridview添加这个： -

 <  < span class =code-leadattribute> asp：ToolkitScriptManager     ID   =  ScriptManager1    runat   =  server >  
 <   / asp：ToolkitScriptManager  >

         <asp:GridView ID="gvshowcourse" runat="server"

                      CellPadding="4" ForeColor="#333333" Height="120px" Width="32%">
                        <footerstyle backcolor="#990000" font-bold="True" forecolor="White" />
                        <rowstyle backcolor="#FFFBD6" forecolor="#333333" />
                        <pagerstyle backcolor="#FFCC66" forecolor="#333333" horizontalalign="Center" />
                        <SelectedRowStyle BackColor="#FFCC66" Font-Bold="True" ForeColor="Navy" />
                        <HeaderStyle BackColor="#990000" Font-Bold="True" ForeColor="White" />
                        <alternatingrowstyle backcolor="White" />
                    
         
         </contenttemplate>
        
       <Aasp:ModalPopupExtender Drag="true" PopupDragHandleControlID="tdHeader" DropShadow="true"

            PopupControlID="pnlcofirmationsms" BackgroundCssClass="modalBackground" TargetControlID="dummy"

            ID="ModalPopupExtender2"  runat="server" CancelControlID="btnCancelRoom">

wheni run shows error as follows

The control with ID 'updatepanel' requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it.

what is the problem in my source page.

解决方案

You need to add the script manager to work with update panel

Add the following

<asp:ScriptManager ID="ScriptManager1" runat="server">
       </asp:ScriptManager>

add this befor your gridview:-

<asp:ToolkitScriptManager ID="ScriptManager1" runat="server">
</asp:ToolkitScriptManager>
