Gridview中显示的值根据数据库中带出的值作更改

前台页面对Gridview增加事件 OnRowDataBound="GridView1_RowDataBound"
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            if (e.Row.Cells[4].Text.Trim() == " ")
                e.Row.Cells[4].Text = "未签核";
            else if (e.Row.Cells[4].Text.Trim() == "AP")
            {
                e.Row.Cells[4].Text = "被否决";
            }
            else
            {
                e.Row.Cells[4].Text = "使用中";
            }
        }
    }
