使用updatrpanel出錯
我使用了UpdatePanel和UpdateProgress ，點擊查詢什麼的都正常，因為我需要將GridView數據導出，在我點擊導出按鈕時候出錯，提示畫面如下：
Sys.WebForms.PageRequestManagerParserErrorException 解析錯誤

查看你的标签是否都成对出现？还有UpdatePanel上面要用到<asp:ScriptManager ID="smPage" runat="server"></asp:ScriptManager>要放在body里面哦！

版主你好，剛問題是解決了！
謝謝，那本來我點擊查詢的時候，會有一個加載的gif的log。那麼現在用了你的辦法，將:ScriptManager
移到body前，就是這個功能實現不了了。

<body>
//当然这里还可以添加<from>之类的标签
<asp:ScriptManager ID="smPage" runat="server"></asp:ScriptManager>
<UpdatePanel>...</UpdatePanel>
</body>

LZ你查看下是不是这样的顺序呢？

全部代码都在这里，比较简单。我只是想用个有加载图标的！所以使用了UpdatePanel

版主。我觉得吧，那个东西放哪边不重要，重要的是一个问题，我现在点查询那个加载的log会出现，我点导出那个按钮，同样出现加载的log
问题就是处在这里，按照道理，应该是我点查询出现加载的log图标，点导出，就会导出excel
那现在问题的关键就在这里了，提示的出错仍然还在！
迷茫中....
版主看来还要麻烦你看看了

        </ContentTemplate>
         <asp:UpdateProgress ID="UpdateProgress1" runat="server"
                AssociatedUpdatePanelID="UpdatePanel1">
                <ProgressTemplate>
                    &nbsp;&nbsp;
                    <img alt="" src="a8.gif" style="width: 36px; height: 32px" /> 數據撈取中，請耐心等待....
                </ProgressTemplate>
            </asp:UpdateProgress>
        <Triggers>
            <asp:AsyncPostBackTrigger ControlID="Button1" EventName="Click" />
        </Triggers>
    </asp:UpdatePanel>
    </form>
</body>

就在刚才的基础上改的，如果你不想加载的时候调用，那加载事件你就设为空，即将           
           if (base.IsPostBack)
            {
                this.query_data();
            }
注释掉。
