Answer 1

我内容页嵌套模板页 ，模板页引用了一些Ajax控件 内容页加载的时候调用了一些模板页上的treeview，dropdownlist，这些控件都在模板页来定义的并且用CascadingDropDown 监控dropdownlist，在内容页调用的时候每当调试到代码的最后 就报以上错误

例：
 <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional" RenderMode="inline">
            <ContentTemplate>                             
                <asp:TreeView ID="TreeView1" runat="server" ImageSet="WindowsHelp">
                <ParentNodeStyle Font-Bold="False" />
                <HoverNodeStyle Font-Underline="True" ForeColor="#6666AA" />
                <SelectedNodeStyle BackColor="#B5B5B5" Font-Underline="False" 
                    HorizontalPadding="0px" VerticalPadding="0px" />
                <NodeStyle Font-Names="Tahoma" Font-Size="8pt" ForeColor="Black" 
                    HorizontalPadding="5px" NodeSpacing="0px" VerticalPadding="1px" />
                
            </asp:TreeView>
            </ContentTemplate>
            
            <Triggers>
                <asp:AsyncPostBackTrigger ControlID="DDL_Class" EventName="SelectedIndexChanged" />
            </Triggers>
        </asp:UpdatePanel>模板页上的public partial class SetKnowledgeInfo : System.Web.UI.Page

        }
        DataTable tmpTable = cmd.Execommddataset(sqlStr);
        if (tmpTable.Rows.Count == 0)
            return;
        tmpTable.Columns.Add("Name");
        foreach (DataRow dr in tmpTable.Rows)
        {
            string code = dr["TypeCode"].ToString().Trim();

        DDL_Type.DataBind();
        DDL_Type.Items.Insert(0, new ListItem("请选择试题类型", ""));        //return;    }内容页上的

你模板页上的dropdownlist相关的代码呢？

Answer 5

试试这个吧：
(我用这个办法获得成功)工具->选项->调试->常规->去掉“要求源文件与原始版本完全匹配”复选框就OK 在解决方案资源管理器中右击解决方案->属性->通用属性->调试源文件。在不查找这些源文件对话框中查看是否有你想要调试的源文件，如果有就删除这一行，保存。
