Gridview 分页

当GridView中显示的记录很多的时候,可以通过GridView的分页功能来分页显示这些记录如图显示

<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>
<%-- //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>

 

 

后台:

public void BindDate()
{

UserDA uDa = new UserDA();
List<SYS_User> list = new List<SYS_User>();
list = uDa.GetUsers();
this.gvUserManager.DataSource = list;
this.gvUserManager.DataBind();
}

protected void gvUserManager_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
this.gvUserManager.PageIndex = e.NewPageIndex;//当前页显示的索引
// 得到该控件
GridView theGrid = 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 = 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
BindDate();

}
