ASP.NET GridView利用PagerTemplate自定义分页

前端：

<asp:GridView ID="GridView1" runat="server" AllowPaging="True">
<PagerTemplate>
当前第:
<%--//((GridView)Container.NamingContainer)就是为了得到当前的控件--%>
<asp:Label ID="LabelCurrentPage" runat="server" Text="<%# ((GridView)Container.NamingContainer).PageIndex + 1 %>"></asp:Label>
页/共:
<%--//得到分页页面的总数--%>
<asp:Label ID="LabelPageCount" runat="server" Text="<%# ((GridView)Container.NamingContainer).PageCount %>"></asp:Label>
页
<%--//如果该分页是首分页，那么该连接就不会显示了.同时对应了自带识别的命令参数CommandArgument--%>
<asp:LinkButton ID="LinkButtonFirstPage" runat="server" CommandArgument="First" CommandName="Page"
Visible='<%#((GridView)Container.NamingContainer).PageIndex != 0 %>'>首页</asp:LinkButton>
<asp:LinkButton ID="LinkButtonPreviousPage" runat="server" CommandArgument="Prev"
CommandName="Page" Visible='<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>'>上一页</asp:LinkButton>
<%--//如果该分页是尾页，那么该连接就不会显示了--%>
<asp:LinkButton ID="LinkButtonNextPage" runat="server" CommandArgument="Next" CommandName="Page"
Visible='<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>'>下一页</asp:LinkButton>
<asp:LinkButton ID="LinkButtonLastPage" runat="server" CommandArgument="Last" CommandName="Page"
Visible='<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>'>尾页</asp:LinkButton>
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="GO" />
</PagerTemplate>
</asp:GridView>

C#后台

// 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
