ASP.NET 2.0中合并 GridView 的表头单元格(转)-白红宇

在实际工作中，往往需要合并表格头部的单元格，下面就是一个实现的例子。运行结果如图：

<%@ Page Language="C#" AutoEventWireup="true" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

ICollection CreateDataSource()

{

System.Data.DataTable dt = new System.Data.DataTable();

System.Data.DataRow dr;

dt.Columns.Add(new System.Data.DataColumn("学生姓名", typeof(System.String)));

dt.Columns.Add(new System.Data.DataColumn("语文", typeof(System.Decimal)));

dt.Columns.Add(new System.Data.DataColumn("数学", typeof(System.Decimal)));

dt.Columns.Add(new System.Data.DataColumn("英语", typeof(System.Decimal)));

for (int i = 0; i < 8; i++)

{

System.Random rd = new System.Random(Environment.TickCount * i); ;

dr = dt.NewRow();

dr[0] = "学生" + i.ToString();

dr[1] = System.Math.Round(rd.NextDouble() * 100, 2);

dr[2] = System.Math.Round(rd.NextDouble() * 100, 2);

dr[3] = System.Math.Round(rd.NextDouble() * 100, 2);

dt.Rows.Add(dr);

}

System.Data.DataView dv = new System.Data.DataView(dt);

return dv;

}

protected void Page_Load(object sender, EventArgs e)

{

if (!IsPostBack)

{

GridView1.BorderColor = System.Drawing.Color.DarkOrange;

GridView1.DataSource = CreateDataSource();

GridView1.DataBind();

}

protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)

{

if (e.Row.RowType == DataControlRowType.Header)

{

GridViewRow rowHeader = new GridViewRow(0, 0, DataControlRowType.Header, DataControlRowState.Normal);

rowHeader.BackColor = System.Drawing.Color.White;

rowHeader.Font.Bold = true;

TableCellCollection cells = e.Row.Cells;

TableCell headerCell = new TableCell();

headerCell.Text = "";

rowHeader.Cells.Add(headerCell);

headerCell = new TableCell();

headerCell.Text = "学生成绩";

headerCell.ColumnSpan = cells.Count - 1;

headerCell.HorizontalAlign = HorizontalAlign.Center;

rowHeader.Cells.Add(headerCell);

rowHeader.Visible = true;

GridView1.Controls[0].Controls.AddAt(0, rowHeader);

}

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)

{

e.Row.Attributes.Add("style", "background:#FFF");

}
