gridview分页的实现

//实现分页

AollowPaging = "true"

//分页数据设置

PageSize = "10"

//分页时触发事件

OnPageIndexChanging = "gv_List_PageIndexChanging"

//这里我给出一个通用显示分页的模板（网上搜的)

<PagerTemplate>
当前第:
//((GridView)Container.NamingContainer)就是为了得到当前的控件
<asp:Label ID="lab_CurrentPage" runat="server" Text="<%# ((GridView)Container.NamingContainer).PageIndex + 1 %>"></asp:Label>
页/共:
//得到分页页面的总数
<asp:Label ID="lab_PageCount" 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="btn_FirstPage" runat="server" CommandArgument="First" CommandName="Page"
Visible='<%#((GridView)Container.NamingContainer).PageIndex != 0 %>'>首页</asp:LinkButton>
<asp:LinkButton ID="btn_PreviousPage" 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="btn_NextPage" runat="server" CommandArgument="Next" CommandName="Page"
Visible='<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>'>下一页</asp:LinkButton>
<asp:LinkButton ID="btn_LastPage" 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="txt_NewPageIndex" 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="btn_Go" runat="server" CausesValidation="False" CommandArgument="-2"
CommandName="Page" Text="GO" />

</PagerTemplate>

对应该事件中代码为:

protectedvoid gvwDesignationName_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
// 得到该控件
GridView gv_list = sender as GridView;
int newPageIndex = 0;
if (e.NewPageIndex==-3)
{
//点击了Go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 = gv_list.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 >= gv_list.PageCount ? gv_list.PageCount - 1 : newPageIndex;

//得到新的值
gv_list.PageIndex = newPageIndex;

//重新绑定
BingGridViewData();
}
