GridView[2]
接着上面GridView 使用方法总结 (一) http://www.cnblogs.com/sufei/archive/2010/03/27/1698590.html#commentform
的内容开始吧。
14.GridView固定表头(不用javascript只用CSS!,很好用):
前台代码

<title>GridView固定表头 清清月儿http://blog.csdn.net/21aspnet </title>
<style>
.Freezing
{
position:relative ;
table-layout:fixed;
top:expression(this.offsetParent.scrollTop);
z-index: 10;
}
.Freezing th{text-overflow:ellipsis;overflow:hidden;white-space: nowrap;padding:2px;}
</style>
</head>
<body style="font-size=12px">
<form id="form1" runat="server">
<div style="overflow-y: scroll; height: 200px;width:300px" id="dvBody">
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="3" OnRowDeleting="GridView1_RowDeleting" OnRowEditing="GridView1_RowEditing"
OnRowUpdating="GridView1_RowUpdating" OnRowCancelingEdit="GridView1_RowCancelingEdit" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" Font-Size="12px" OnRowCreated="GridView1_RowCreated" >
<FooterStyle BackColor="White" ForeColor="#000066" />
<Columns>
<asp:BoundField DataField="身份证号码" HeaderText="编号" ReadOnly="True" />
<asp:BoundField DataField="邮政编码" HeaderText="邮政编码" SortExpression="邮政编码" />
<asp:BoundField DataField="家庭住址" HeaderText="家庭住址" />
<asp:BoundField DataField="姓名" HeaderText="姓名" />
</Columns>
<RowStyle ForeColor="#000066" />
<SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" CssClass="ms-formlabel DataGridFixedHeader"/>
<HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" CssClass="Freezing"/>
</asp:GridView>
</div>
</form>
</body>
</html>
用法:CSS设如上的样式,HeaderStyle加CssClass="Freezing,套住GridView的Div设置高度宽度 <div style="overflow-y: scroll; height: 200px;width:200px" >
15.GridView合并表头多重表头无错完美版(以合并3列3行举例)

16.GridView突出显示某一单元格(例如金额低于多少,分数不及格等)
解决方案:主要是绑定后过滤
![](https://images.cnblogs.com/OutliningIndicators/ContractedBlock.gif)
for (int i = 0; i <= GridView1.Rows.Count - 1; i++)
{
DataRowView mydrv = myds.Tables["飞狐工作室"].DefaultView[i];
string score = Convert.ToString(mydrv["起薪"]);
if (Convert.ToDouble(score) < 34297.00)//大家这里根据具体情况设置可能ToInt32等等
{
GridView1.Rows[i].Cells[4].BackColor = System.Drawing.Color.Red;
}
}
sqlcon.Close();

17.GridView加入自动求和求平均值小计
解决方法:
![](https://images.cnblogs.com/OutliningIndicators/ContractedBlock.gif)
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowIndex >= 0)
{
sum += Convert.ToDouble(e.Row.Cells[6].Text);
}
else if (e.Row.RowType == DataControlRowType.Footer)
{
e.Row.Cells[5].Text = "总薪水为:";
e.Row.Cells[6].Text = sum.ToString();
e.Row.Cells[3].Text = "平均薪水为:";
e.Row.Cells[4].Text = ((int)(sum / GridView1.Rows.Count)).ToString();
}
}
后台所有代码:
![](https://images.cnblogs.com/OutliningIndicators/ContractedBlock.gif)
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Data.SqlClient;
using System.Drawing;
public partial class Default7 : System.Web.UI.Page
{
SqlConnection sqlcon;
SqlCommand sqlcom;
string strCon = "Data Source=(local);Database=北风贸易;Uid=sa;Pwd=sa";
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
bind();
}
}
protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
{
GridView1.EditIndex = e.NewEditIndex;
bind();
}
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
sqlcon = new SqlConnection(strCon);
string sqlstr = "update 飞狐工作室 set 姓名='"
+ ((TextBox)(GridView1.Rows[e.RowIndex].Cells[1].Controls[0])).Text.ToString().Trim() + "',家庭住址='"
+ ((TextBox)(GridView1.Rows[e.RowIndex].Cells[3].Controls[0])).Text.ToString().Trim() + "' where 身份证号码='"
+ GridView1.DataKeys[e.RowIndex].Value.ToString() + "'";
sqlcom = new SqlCommand(sqlstr, sqlcon);
sqlcon.Open();
sqlcom.ExecuteNonQuery();
sqlcon.Close();
GridView1.EditIndex = -1;
bind();
}
protected void GridView1_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
{
GridView1.EditIndex = -1;
bind();
}
public void bind()
{
string sqlstr = "select top 5 * from 飞狐工作室";
sqlcon = new SqlConnection(strCon);
SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon);
DataSet myds = new DataSet();
sqlcon.Open();
myda.Fill(myds, "飞狐工作室");
GridView1.DataSource = myds;
GridView1.DataKeyNames = new string[] { "身份证号码" };
GridView1.DataBind();
sqlcon.Close();
}
private double sum = 0;//取指定列的数据和
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowIndex >= 0)
{
sum += Convert.ToDouble(e.Row.Cells[6].Text);
}
else if (e.Row.RowType == DataControlRowType.Footer)
{
e.Row.Cells[5].Text = "总薪水为:";
e.Row.Cells[6].Text = sum.ToString();
e.Row.Cells[3].Text = "平均薪水为:";
e.Row.Cells[4].Text = ((int)(sum / GridView1.Rows.Count)).ToString();
}
}
}
前台:唯一的花头就是设置ShowFooter="True" ,否则默认表头为隐藏的!
![](https://images.cnblogs.com/OutliningIndicators/ContractedBlock.gif)
OnRowUpdating="GridView1_RowUpdating" OnRowCancelingEdit="GridView1_RowCancelingEdit" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" Font-Size="12px" OnRowDataBound="GridView1_RowDataBound" ShowFooter="True" >
<FooterStyle BackColor="White" ForeColor="#000066" />

<asp:BoundField DataField="身份证号码" HeaderText="编号" ReadOnly="True" />
<asp:BoundField DataField="姓名" HeaderText="姓名" />
<asp:BoundField DataField="出生日期" HeaderText="邮政编码" />

<asp:BoundField DataField="邮政编码" HeaderText="邮政编码" />
<asp:BoundField DataField="起薪" HeaderText="起薪" />

<SelectedRowStyle BackColor="#669999" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="White" ForeColor="#000066" HorizontalAlign="Left" CssClass="ms-formlabel DataGridFixedHeader"/>
<HeaderStyle BackColor="#006699" Font-Bold="True" ForeColor="White" />
</asp:GridView>
18.GridView数据导入Excel/Excel数据读入GridView
页面增加一个按钮,单击事件添加如下方法:
![](https://images.cnblogs.com/OutliningIndicators/ContractedBlock.gif)
{
Export("application/ms-excel", "学生成绩报表.xls");
}
private void Export(string FileType, string FileName)
{
Response.Charset = "GB2312";
Response.ContentEncoding = System.Text.Encoding.UTF7;
Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(FileName, Encoding.UTF8).ToString());
Response.ContentType = FileType;
this.EnableViewState = false;
StringWriter tw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(tw);
GridView1.RenderControl(hw);
Response.Write(tw.ToString());
Response.End();
}
//如果没有下面方法会报错类型“GridView”的控件“GridView1”必须放在具有 runat=server 的窗体标记内
public override void VerifyRenderingInServerForm(Control control)
{
}
还有由于是文件操作所以要引入名称空间IO和Text
后台代码:
![](https://images.cnblogs.com/OutliningIndicators/ContractedBlock.gif)
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Data.SqlClient;
using System.Drawing;
using System.IO;
using System.Text;
public partial class Default7 : System.Web.UI.Page
{
SqlConnection sqlcon;
SqlCommand sqlcom;
string strCon = "Data Source=(local);Database=北风贸易;Uid=sa;Pwd=sa";
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
bind();
}
}
public void bind()
{
string sqlstr = "select top 5 * from 飞狐工作室";
sqlcon = new SqlConnection(strCon);
SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon);
DataSet myds = new DataSet();
sqlcon.Open();
myda.Fill(myds, "飞狐工作室");
GridView1.DataSource = myds;
GridView1.DataKeyNames = new string[] { "身份证号码" };
GridView1.DataBind();
sqlcon.Close();
}
protected void Button1_Click(object sender, EventArgs e)
{
Export("application/ms-excel", "学生成绩报表.xls");
}
private void Export(string FileType, string FileName)
{
Response.Charset = "GB2312";
Response.ContentEncoding = System.Text.Encoding.UTF7;
Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(FileName, Encoding.UTF8).ToString());
Response.ContentType = FileType;
this.EnableViewState = false;
StringWriter tw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(tw);
GridView1.RenderControl(hw);
Response.Write(tw.ToString());
Response.End();
}
public override void VerifyRenderingInServerForm(Control control)
{
}
}

<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="导出" />
读取Excel数据的代码:这个很简单的
private DataSet CreateDataSource()
{
string strCon;
strCon = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + Server.MapPath("excel.xls") + "; Extended Properties=Excel 8.0;";
OleDbConnection olecon = new OleDbConnection(strCon);
OleDbDataAdapter myda = new OleDbDataAdapter("SELECT * FROM [Sheet1$]", strCon);
DataSet myds = new DataSet();
myda.Fill(myds);
return myds;
}
protected void Button1_Click(object sender, EventArgs e)
{
GridView1.DataSource = CreateDataSource();
GridView1.DataBind();
}
由于时间关系,这个文章先到此。有时间再写,其实还有很多技巧,不过我觉得如果能融汇贯通应该可以举一反三。
--------------------------------------------------------------------------------------------------------------------------------
文章到这里算是把月儿老师的文章整理完了
应该说说我的想法了,呵呵,真多啊,月儿老师真能写,呵呵
月儿老师呢没有使用Sqlhelper或是什么三层工厂等更高一级的东西,只是使用简单直接的方法来实现 功能 ,让大家明白这个功能可以实现,但是大家一定不要以为
老师只会这些,其实老师是想让高手看方法,水平一般的可以得到启示,而刚入门的可以直接拿来用并得到提高,我感觉应该是这样意吧
如果写的太深了初学都就看不明白了,而水平高点的会感觉不舒服,高手会不绡于看,因为他们也会。
月儿老师的最后一项 18.GridView数据导入Excel/Excel数据读入GridView
说到导入大家一定能想到导出的功能 ,在C# 将数据导出到Excel汇总 http://www.cnblogs.com/sufei/archive/2009/05/23/1487540.html
这里有总结的不少导出的方法有兴趣的朋友可以去看看。
关于Gridview的使用我也写过一个,不过写的没有这么详细,可以参考 一下
1.解决DataGridView绑定List后不能排序的问题

这里强说不是写的Girdview的但是这个问题很容易碰到加个导航吧在这里
