GridView 问题？

Question

怎样在gridview里合并单元格？

Answer 1

在GridView_RowCreated上作文章。这可能是老办法了。我简单做了个测试。
效果：点击
<form id="form1" runat="server">
    <div>
        <asp:GridView ID="GridView1" runat="server" onrowcreated="GridView1_RowCreated">
        </asp:GridView>
    </div>
</form>
protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
            GridView1.DataSource = GetTable();
            GridView1.DataBind();
    }
}private DataTable GetTable()
{
        DataTable dt = new DataTable();        DataColumn dc = new DataColumn();
        dc.ColumnName = "ID";
        dc.AutoIncrement = true;
        dc.AutoIncrementSeed = 1;
        dc.AutoIncrementStep = 1;        dt.Columns.Add(dc);
        dt.PrimaryKey = new DataColumn[] { dc };        dt.Columns.Add("FirstName", typeof(string));
        dt.Columns.Add("LastName", typeof(string));        dt.Columns.Add("City", typeof(string));
        dt.Columns.Add("Street", typeof(string));        DataRow dr = dt.NewRow();
        dr["FirstName"] = "元甲";
        dr["LastName"] = "霍";
        dr["City"] = "上海";
        dr["Street"] = "南京路325号";
        dt.Rows.Add(dr);        dr = dt.NewRow();
        dr["FirstName"] = "真";
        dr["LastName"] = "陈";
        dr["City"] = "佛山";
        dr["Street"] = "东山路15号";
        dt.Rows.Add(dr);        return dt;}
protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
{
        if (e.Row.RowType == DataControlRowType.Header)
        {
            // 第一行表头
            TableCellCollection tcHeader = e.Row.Cells;
            tcHeader.Clear();
            tcHeader.Add(new TableHeaderCell());
            tcHeader[0].Attributes.Add("rowspan", "3"); //跨三行。
            tcHeader[0].Text = "人员ID";            tcHeader.Add(new TableHeaderCell());
            tcHeader[1].Attributes.Add("colspan", "4"); //跨四列
            tcHeader[1].Text = "基本资料</th></tr><tr>"; // 作弊            // 第二行表头
            tcHeader.Add(new TableHeaderCell());
            tcHeader[2].Attributes.Add("colspan", "2");
            tcHeader[2].Text = "姓名";
            
            tcHeader.Add(new TableHeaderCell());
            tcHeader[3].Attributes.Add("colspan", "2");            
            tcHeader[3].Text = "联系方式</th></tr><tr>"; //作弊            // 第三行表头
            tcHeader.Add(new TableHeaderCell());
            tcHeader[4].Text = "名";            tcHeader.Add(new TableHeaderCell());
            tcHeader[5].Text = "姓";            tcHeader.Add(new TableHeaderCell());
            tcHeader[6].Text = "城市";            tcHeader.Add(new TableHeaderCell());
            tcHeader[7].Text = "街道";
            
                    }
