C# 无法注销ID为'；AjaxPanel'；因为它没有向ScriptManager注册。如果

请注意，我有这个错误，我不能摆脱它，我有一个用户控件在另一个用户控件的子控件面板中

父控件包含一个Radgrid，希望有一个editformTemplate，子控件加载在其中，我将在代码中显示u：

<EditFormSettings EditFormType="Template">
                <EditColumn FilterControlAltText="Filter EditCommandColumn column">
                </EditColumn>
                <FormStyle BackColor="#FCFCFC"></FormStyle>
                <FormTemplate>
                       <table>
                            <tr>
                                <td class="LblWidth" style="padding-top: 5px;">
                             <asp:Label ID="Label1" runat="server" Text="Center logo:">
                                    </asp:Label>
                                </td>
                                <td style="padding-top: 10px;">

                 <uc1:MAYAUploadImageControl ID="UploadImageControl1" runat="server" />


                                    <span class="redSpan">
                                    </span>
                                </td>
                            </tr>
                        </table>
   </FormTemplate>
            </EditFormSettings>

很抱歉，我的解释很混乱，但是我在这个问题上被困了好几天，我无法解决它。

根据下面链接中的信息，看起来

RadAjaxPanel

正在从它所属的控件集合中移动或移除。第三个链接包含Telerik特定的解决方法

你能发布完整的错误信息吗？另外，您不需要父窗体中的

ScriptManager

吗？我的脚本管理器位于母版页中，完整错误是：无法注销ID为“AjaxPanel”的UpdatePanel，因为它未向ScriptManager注册。如果从控件树中删除UpdatePanel，然后再次添加，则可能会发生这种情况，这是不受支持的。参数名称：updatePanel
