GridView 使用方法总结（二）

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)：

        <style>

   {

   position:relative ;
   table-layout:fixed;
   top:expression(this.offsetParent.scrollTop);

<body style="font-size=12px">
    <form id="form1" runat="server">
    <div style="overflow-y: scroll; height: 200px;300px" id="dvBody">
                   <asp:GridView ID="GridView1" runat="server"    AutoGenerateColumns="False" CellPadding="3" OnRowDeleting="GridView1_RowDeleting" OnRowEditing="GridView1_RowEditing"

                        <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;200px" >

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

代码

GridView1.DataBind();
        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：

代码

private double sum = 0;//取指定列的数据和，你要根据具体情况对待可能你要处理的是int
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();

        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！

代码

<asp:GridView ID="GridView1" runat="server"    AutoGenerateColumns="False" CellPadding="3"  OnRowEditing="GridView1_RowEditing"
                        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" />
                        <Columns>
                            <asp:CommandField HeaderText="编辑" ShowEditButton="True" />
                            <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="家庭住址" HeaderText="家庭住址"  />
                            <asp:BoundField DataField="邮政编码" HeaderText="邮政编码" />
                            <asp:BoundField DataField="起薪" HeaderText="起薪"  />

                        </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" />
                    </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：

代码

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();
    }

//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：

代码

using System;
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)
    {
    }

}

前台

代码

<asp:GridView ID="GridView1" runat="server"    AutoGenerateColumns="False" CellPadding="3"
                         BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" Font-Size="12px"   >
                        <FooterStyle BackColor="White" ForeColor="#000066" />
                        <Columns>
                            <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="家庭住址" HeaderText="家庭住址"  />
                            <asp:BoundField DataField="邮政编码" HeaderText="邮政编码" />
                            <asp:BoundField DataField="起薪" HeaderText="起薪"  />

                        </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" />
                    </asp:GridView>
        <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
