使用GridView控件，利用其PageIndexChanging事件实现分页却不能实现，请问该如何解决，谢谢！
html页面的代码如下：<asp:GridView CssClass ="top" ID="gv_class_list" runat="server" AutoGenerateColumns ="false" DataKeyNames ="classID" CellPadding ="4"
GridLines ="none" Width ="100%" OnPageIndexChanging="gv_class_list_PageIndexChanging" PageIndex ="15" AllowPaging ="true" >
<Columns >
<asp:BoundField DataField ="grade" HeaderText ="年级" />
<asp:HyperLinkField DataNavigateUrlFields="classID" DataNavigateUrlFormatString="" HeaderText ="专业(专业方向)" DataTextField="speciality" />
<asp:BoundField DataField ="numbers" HeaderText ="人数" />
<asp:BoundField DataField ="headTeacher" HeaderText ="班主任" />
</Columns>
<PagerTemplate>
<table style="font-size :12px;height:50px;">
<tr>
<td> 总共<asp:Label ID="Label1" runat="server" Text="<%#((GridView)Container.NamingContainer).PageCount %>"></asp:Label>页 </td>
<td> 第<asp:Label ID="Label2" runat="server" Text="<%#((GridView)Container.NamingContainer).PageIndex+1 %>"></asp:Label>页 </td>
<td> <asp:LinkButton ID="LinkButton1" runat="server" CommandArgument ="1" CommandName ="Page" Enabled ="<%#((GridView)Container.NamingContainer).PageIndex!=0 %>">首页</asp:LinkButton> </td>
<td><asp:LinkButton ID="LinkButton2" runat="server" CommandArgument ="Prev" CommandName ="Page" Enabled ="<%#((GridView)Container.NamingContainer).PageIndex!=0 %>">上一页</asp:LinkButton> </td>
<td><asp:LinkButton ID="LinkButton3" runat="server" CommandArgument ="Next" CommandName ="Page" Enabled ="<%#((GridView)Container.NamingContainer).PageIndex!=((GridView)Container.NamingContainer).PageCount-1 %>">下一页 </asp:LinkButton> </td>
<td><asp:LinkButton ID="LinkButton4" runat="server" CommandArgument ="Last" CommandName ="Page" Enabled ="<%#((GridView)Container.NamingContainer).PageIndex!=((GridView)Container.NamingContainer).PageCount-1 %>">尾页</asp:LinkButton> </td>
<td><asp:LinkButton ID="LinkButton5" runat="server" CommandArgument ="-1" CommandName ="Page" ValidationGroup="1" >GO</asp:LinkButton> </td>
<td><asp:TextBox ID="txtNum" runat="server" Width="30px" Text ="<%#((GridView)Container.NamingContainer).PageIndex+1 %>" ValidationGroup="1"></asp:TextBox>
<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server" ErrorMessage="" ValidationExpression ="^\d+$" ControlToValidate ="txtNum" ValidationGroup="1"></asp:RegularExpressionValidator></td>
</tr>
</table>
</PagerTemplate>
<RowStyle HorizontalAlign="center" />
</asp:GridView>
后台代码如下：
protected void bind()
{
DataSet ds = null;
try
{
ds=DataBusiness.DataExecute.ExecuteDataset(DataBusiness.DataExecute.CONN_STRING, CommandType.StoredProcedure, "getAllClass");
}
catch (SqlException ex)
{
throw new Exception(ex.Message, ex);
}
if (ds.Tables[0].Rows.Count != 0)
{
this.gv_class_list .DataSource = ds;
this.gv_class_list .DataBind();
//this.Count = ds.Tables[0].Rows.Count;
}
}
protected void gv_class_list_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
GridView gv = (GridView)sender;
int newPageIndex = 0;
if (2 == e.NewPageIndex)
{
TextBox tb = null;
GridViewRow gvr = gv.BottomPagerRow;
if (gvr != null)
{
tb = (TextBox)gvr.FindControl("txtNum");
}
if (tb != null)
{
newPageIndex = int.Parse(tb.Text) - 1;
}
}
else
{
newPageIndex = e.NewPageIndex;
}
newPageIndex = newPageIndex <= 0 ? 0 : newPageIndex;
this.gv_class_list.PageIndex = newPageIndex;
//分页后重新绑定数据源
this.bind();

还是问题，这段代码没显示出来！没效果！
