ASP.NET GridView利用PagerTemplate自定义分页

<PagerTemplate>
<asp:Label runat="server" ID="currentpage" Text="第"></asp:Label>
<asp:Label ID="LabelCurrentPage" runat="server" Text="<%# ((GridView)Container.NamingContainer).PageIndex + 1 %>"></asp:Label>
<asp:Label runat="server" ID="Lblye" Text="页"></asp:Label>
<span style="font-weight:bold">/</span>
<asp:Label runat="server" ID="lbl_gong" Text="共"></asp:Label>
<asp:Label ID="LabelPageCount" runat="server" Text="<%# ((GridView)Container.NamingContainer).PageCount %>"></asp:Label>
<asp:Label runat="server" ID="Label2" Text="页"></asp:Label>
<%--  <asp:Label ID="Scount1" runat="server" Text="共"></asp:Label>
<asp:Label ID="lbl_RecordScount" runat="server"></asp:Label>
<asp:Label ID="Scount2" runat="server" Text="条记录"></asp:Label> --%>
<asp:Label runat="server" ID="TotalItemsLabel"  Text="<%# Container.TotalRowCount%>" />条记录
<asp:LinkButton ID="LinkButtonFirstPage" runat="server" CommandArgument="First" CommandName="Page"
Enabled="<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>">首页</asp:LinkButton><%--Enabled属性可以改成Visible--%>
<span style="font-weight:bold">|</span>
<asp:LinkButton ID="LinkButtonPreviousPage" runat="server" CommandArgument="Prev"
CommandName="Page" Enabled="<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>">上一页</asp:LinkButton>
<span style="font-weight:bold">|</span>
<asp:LinkButton ID="LinkButtonNextPage" runat="server" CommandArgument="Next" CommandName="Page"
Enabled="<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>">下一页</asp:LinkButton>
<span style="font-weight:bold">|</span>
<asp:LinkButton ID="LinkButtonLastPage" runat="server" CommandArgument="Last" CommandName="Page"
Enabled="<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>">尾页</asp:LinkButton>
跳转到第
<asp:TextBox ID="txtNewPageIndex" runat="server" Width="20px" Text='<%# ((GridView)Container.Parent.Parent).PageIndex + 1 %>' />页
<%--这里将CommandArgument即使点击该按钮e.newIndex 值为3--%>
<asp:LinkButton ID="btnGo" runat="server" CausesValidation="False" CommandArgument="-2"
CommandName="Page" Text="跳转" />
<asp:RangeValidator ID="Range_Validator" runat="server" ErrorMessage="页码超出范围！" MaximumValue="100" MinimumValue="1"
ControlToValidate="txtNewPageIndex" ForeColor="Red" Type="Integer"></asp:RangeValidator>
</PagerTemplate>

protected void EmployeeDirectory_OnPageIndexChanging(object sender, GridViewPageEventArgs e)
{
// EmployeeGrid.PageIndex = e.NewPageIndex;
// InitialGridView_EmployeeDirectory();
// 得到该控件
GridView theGrid = sender as GridView;
int newPageIndex = 0;
if (e.NewPageIndex == -3)
{
//点击跳转按钮
TextBox txtNewPageIndex = null;

//GridView较DataGrid提供了更多的API，获取分页块可以使用BottomPagerRow 或者TopPagerRow，当然还增加了HeaderRow和FooterRow
GridViewRow pagerRow = theGrid.BottomPagerRow;

if (pagerRow != null)
{
//得到text控件
txtNewPageIndex = pagerRow.FindControl("txtNewPageIndex") as TextBox;
}
if (txtNewPageIndex != null)
{
//得到索引
newPageIndex = int.Parse(txtNewPageIndex.Text) - 1;
}
}
else
{
//点击了其他的按钮
newPageIndex = e.NewPageIndex;
}
//防止新索引溢出
newPageIndex = newPageIndex < 0 ? 0 : newPageIndex;
newPageIndex = newPageIndex >= theGrid.PageCount ? theGrid.PageCount - 1 : newPageIndex;
//得到新的值
theGrid.PageIndex = newPageIndex;
//重新绑定
