GridView突出显示某一单元格（例如金额低于多少，分数不及格等）
效果图：
-
解决方案：主要是绑定后过滤
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();全部后台代码：
