GridView分页用法
本人通过学习GridView，查看的相关资料，总结了实现上一页、下一页、首页、尾页、页面跳转的方法如下
新建一个.aspx页面：
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Sjy_Form.aspx.cs" Inherits="Sjy_Form" %>
<%@ OutputCache Duration="2" VaryByParam="*" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>数据源管理窗口</title>
<script language="javascript" src="Js/calendar.js" charset="gb2312"></script>
<style>
.c{
FILTER: alpha(style=1,opacity=0,finishOpacity=1,startX=1 , startY=1 , finishX=99, finishY=99 );
}
html{
html { overflow-x:hidden; }
}
</style>
</head>
<body>
<form id="form1" runat="server">
<div id="b" style="left: 11px; overflow-x :auto; overflow-y:auto;
width: 645px; position: absolute; top: 419px; height: 195px">
<asp:GridView ID="GridView1" runat="server" AllowPaging="True" AutoGenerateColumns="False"
CellPadding="3" Height="1px" Width="1005px" PageSize="5" Font-Size="10pt" BackColor="White" BorderColor="#E7E7FF" BorderWidth="1px" OnRowDataBound="GridView1_RowDataBound">
<Columns>
<asp:BoundField DataField="sjy_id" HeaderText="数据源编号" SortExpression="sjy_id" >
<HeaderStyle HorizontalAlign="Left" />
</asp:BoundField>
<asp:BoundField DataField="sjymc" HeaderText="数据源名称" SortExpression="sjymc" >
<HeaderStyle HorizontalAlign="Left" />
</asp:BoundField>
<asp:BoundField DataField="sjybt" HeaderText="数据源标题" SortExpression="sjybt" >
<HeaderStyle HorizontalAlign="Left" />
<ItemStyle Wrap="False" />
</asp:BoundField>
<asp:BoundField DataField="jlr" HeaderText="建立人">
<HeaderStyle HorizontalAlign="Left" />
</asp:BoundField>
<asp:BoundField DataField="jlrq" HeaderText="建立日期" DataFormatString="{0:d}">
<HeaderStyle HorizontalAlign="Left" />
<ItemStyle Wrap="False" />
</asp:BoundField>
</Columns>
<PagerTemplate>
<table width="100%">
<tr>
<td style="text-align: right">
第<asp:Label ID="lblPageIndex" runat="server" Text='<%# ((GridView)Container.Parent.Parent).PageIndex + 1 %>'></asp:Label>页
共/<asp:Label ID="lblPageCount" runat="server" Text='<%# ((GridView)Container.Parent.Parent).PageCount %>'></asp:Label>页
<asp:LinkButton ID="btnFirst" runat="server" CausesValidation="False" CommandArgument="First"
CommandName="Page" Text="首页" OnClick="LinkBtn_Sjy_Click"></asp:LinkButton>
<asp:LinkButton ID="btnPrev" runat="server" CausesValidation="False" CommandArgument="Prev"
CommandName="Page" Text="上一页" OnClick="LinkBtn_Sjy_Click"></asp:LinkButton>
<asp:LinkButton ID="btnNext" runat="server" CausesValidation="False" CommandArgument="Next"
CommandName="Page" Text="下一页" OnClick="LinkBtn_Sjy_Click"></asp:LinkButton>
<asp:LinkButton ID="btnLast" runat="server" CausesValidation="False" CommandArgument="Last"
CommandName="Page" Text="尾页" OnClick="LinkBtn_Sjy_Click"></asp:LinkButton>
<asp:TextBox ID="txtNewPageIndex" runat="server" Text='<%# ((GridView)Container.Parent.Parent).PageIndex + 1 %>'
Width="20px"></asp:TextBox>
<asp:LinkButton ID="btnGo" runat="server" CausesValidation="False" CommandArgument="Go"
CommandName="Page" Text="GO" OnClick="LinkBtn_Sjy_Click"></asp:LinkButton><!-- here set the CommandArgument of the Go Button to '-1' as the flag -->
</td>
</tr>
</table>
</PagerTemplate>
<FooterStyle BackColor="#B5C7DE" ForeColor="#4A3C8C" />
<RowStyle BackColor="#E7E7FF" ForeColor="#4A3C8C" />
<PagerStyle BackColor="#E7E7FF" ForeColor="#4A3C8C" HorizontalAlign="Right" />
<SelectedRowStyle BackColor="#738A9C" Font-Bold="True" ForeColor="#F7F7F7" />
<HeaderStyle BackColor="#7481BA" Font-Bold="True" ForeColor="Yellow" HorizontalAlign="Left" Wrap="False" />
<AlternatingRowStyle BackColor="#F7F7F7" />
</asp:GridView>
<asp:Label ID="Lab_info" runat="server" ForeColor="red"></asp:Label>
</div>
</form>
</body>
</html>
后台代码：
#region Gridview数据填充
/// <summary>
/// Gridview数据填充
/// </summary>
private void Gridview_Bind()
{
sqlStr = "select * from sys_pcedm_sjy";
DataSet ds = OracleDB.Dataset(sqlStr);
GridView1.DataSource = ds;
GridView1.DataBind();
if (ds.Tables[0].Rows.Count == 0)
{
GridView1.Visible = false;
Lab_info.Text = "当前数据记录为空";
}
else
{
GridViewRow pagerRow = GridView1.BottomPagerRow;
LinkButton linkBtnFirst = (LinkButton)pagerRow.Cells[0].FindControl("btnFirst");
LinkButton linkBtnPrev = (LinkButton)pagerRow.Cells[0].FindControl("btnPrev");
LinkButton linkBtnNext = (LinkButton)pagerRow.Cells[0].FindControl("btnNext");
LinkButton linkBtnLast = (LinkButton)pagerRow.Cells[0].FindControl("btnLast");
if (this.GridView1.PageIndex == 0)
{
linkBtnFirst.Enabled = false;
linkBtnPrev.Enabled = false;
}
else
{
linkBtnFirst.Enabled = true;
linkBtnPrev.Enabled = true;
}
if (GridView1.PageIndex == GridView1.PageCount - 1)
{
linkBtnLast.Enabled = false;
linkBtnNext.Enabled = false;
}
else
{
linkBtnLast.Enabled = true;
linkBtnNext.Enabled = true;
}
for (int i = 0; i <= GridView1.Rows.Count - 1; i++)
{
DataRowView mydrv;
string gIntro;
if (GridView1.PageIndex == 0)
{
mydrv = ds.Tables["data"].DefaultView[i];
gIntro = Convert.ToString(mydrv["sjysm"]); //这里取出单元格数据,
GridView1.Rows[i].Cells[7].Text = SubStr(gIntro, 4);//自定义了一个函数SubStr进行截取,返回的值重新绑定到gridview控件的单元格中.
}
else
{
mydrv = ds.Tables["data"].DefaultView[i + (5 * GridView1.PageIndex)];
gIntro = Convert.ToString(mydrv["sjysm"]);
GridView1.Rows[i].Cells[3].Text = SubStr(gIntro, 4);
}
}
}
}
#endregion
如果大家有其它好的方法，希望能提出。
