gridview自定义分页无法触发PageIndexChanging事件?

Question

自定义了一个GridView分页.但是为什么无法进入onpageindexchanging="gv_PageIndexChanging" 事件.------------------------------------
<asp:GridView ID="gv" runat="server" ForeColor="Black" Width="100%" 
                              CssClass="gridviewStyle" EnableViewState="false"
                        EmptyDataText="暂无数据，请添加！" DataKeyNames="KEYID" CellPadding="0" AutoGenerateColumns="False"
                        PageSize="19" BackColor="LightBlue" BorderStyle="None" AllowPaging="True"  onpageindexchanging="gv_PageIndexChanging"
                             onrowdatabound="gv_RowDataBound">
---------------------------------
分页代码:<PagerTemplate>
                    <table style="font-size: 12px" width="100%" >
                    <tbody>
                        <tr>
                            <td style="height: 18px; text-align: right">
第<asp:Label id="lblPageIndex" runat="server" text='<%# ((GridView)Container.Parent.Parent).PageIndex + 1  %>' />页
                                共/<asp:Label id="lblPageCount" runat="server" text='<%# ((GridView)Container.Parent.Parent).PageCount  %>' />页 
                                <asp:linkbutton id="btnFirst" runat="server" causesvalidation="False" commandargument="First" commandname="Page" text="首页" />
                              <asp:linkbutton id="btnPrev" runat="server" causesvalidation="False" commandargument="Prev" commandname="Page" text="上一页" />
                             <asp:linkbutton id="btnNext" runat="server" causesvalidation="False" commandargument="Next" commandname="Page" text="下一页" />                          
                             <asp:linkbutton id="btnLast" runat="server" causesvalidation="False" commandargument="Last" commandname="Page" text="尾页" />                                            
                             <asp:TextBox id="txtNewPageIndex" runat="server" width="20px" text='<%# ((GridView)Container.Parent.Parent).PageIndex + 1  %>' />
                             <asp:linkbutton id="btnGo" runat="server" causesvalidation="False" commandargument="-1" commandname="Page" text="GO" />
                             </td>
                        </tr>
                    </tbody>
                </table>                             </PagerTemplate>-------------------------------------------------------问题来了:<asp:linkbutton id="btnNext" runat="server" causesvalidation="False" commandargument="Next" commandname="Page" text="下一页" />   
点击下一页,那个gv_PageIndexChanging事件无法激发. 所以页面显示[无法显示该网页].之前有2个页面都做好了的.分页能成功.这里为什么就失灵了?是不是什么东西有冲突导致?小弟实在琢磨不透了.忘各位大虾帮把劲`

Answer 1

就楼主提供代码,试了一下,完全没问题,onpageindexchanging是可以触发的!
问题肯定不是代码!!

Answer 2

接2楼!把GridView删掉,重新创建onpageindexchanging事件试试!

Answer 3

检查页面是否有其他设置
其他事件是否正常如onrowdeleting="GridView1_RowDeleting" onrowediting="GridView1_RowEditing" 

Answer 4

貌似是数据源太大了?
我试了下  SQL加了句  top 100
就能正常分页`  原来有接近100页
这样也行?
