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

 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

 

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();
            
        }
    }

后台所有代码：

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;

 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！

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

     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 " );

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();
    }
