GridView自定义表头、复合表头、绑定

1、自定义表头

//自定义表头
protected void create(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.Header)
    {
        TableCellCollection tcHeader = e.Row.Cells;
        //清除自动生成的表头
        tcHeader.Clear();

        //查询数据库字段生成表头
        StringBuilder strSQL = new StringBuilder();
        strSQL.Clear();
        strSQL.Append("select name from syscolumns where id = object_id(N'data_table');");
        string strsql = strSQL.ToString();
        DataTable dt = DB.GetDataBySQL(strsql);

        //自动添加表头
        int count = dt.Rows.Count;
        for (int i = 0; i < count; i++)
        {
            string strdt = dt.Rows[i][0].ToString();
            tcHeader.Add(new TableHeaderCell());
            tcHeader[i].Text = strdt;
        }
    }
}

2、复合表头

    //复合表头
    protected void create(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.Header)
        {
            TableCellCollection tcHeader = e.Row.Cells;
            //清除自动生成的表头
            tcHeader.Clear();

            tcHeader.Add(new TableHeaderCell());
            tcHeader[0].RowSpan = 2;
            tcHeader[0].Text = "姓名";

            tcHeader.Add(new TableHeaderCell());
            tcHeader[1].RowSpan = 2;
            tcHeader[1].Text = "班级";

            tcHeader.Add(new TableHeaderCell());
            tcHeader[2].ColumnSpan = 3;
            tcHeader[2].Text = "成绩";

            tcHeader.Add(new TableHeaderCell());
            tcHeader[3].RowSpan = 2;
            tcHeader[3].Text = "总排名</th></tr><tr>";

            tcHeader.Add(new TableHeaderCell());
            tcHeader[4].Text = "语文";
            tcHeader[4].BackColor = System.Drawing.ColorTranslator.FromHtml("#1CB89E");     //设置单元格背景颜色

            tcHeader.Add(new TableHeaderCell()); 
            tcHeader[5].Text = "数学";
            tcHeader[5].BackColor = System.Drawing.ColorTranslator.FromHtml("#1CB89E");     //设置单元格背景颜色

            tcHeader.Add(new TableHeaderCell()); 
            tcHeader[6].Text = "英语"; 
            tcHeader[6].BackColor = System.Drawing.ColorTranslator.FromHtml("#1CB89E"); //设置单元格背景颜色 
        }
    }

3、数据绑定

    //GridView内容绑定
    public void GridViewBind()
    {
        StringBuilder strSQL = new StringBuilder();
        strSQL.Clear();
        strSQL.Append("select * from data_table");
        string strsql = strSQL.ToString();
        GridView1.DataSource = DB.GetDataBySQL(strsql);
        GridView1.DataBind();

    }
