行绑定时间.aspx.cs代码如下：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace ASP.NET练习
{
public partial class 行绑定事件 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Onrowdatabound(object sender, GridViewRowEventArgs e)//GridViewRowEventArgs e
{
Response.Write(e.Row.RowType + "<br/>");//RowType类型有
if (e.Row.RowType == DataControlRowType.DataRow) {//RoeType共有三种类型：header datarow footer
for (int i = 2; i <= 6; i++) {
TableCell mytc = e.Row.Cells[i];//获取单元格
Single _f = Convert.ToSingle(mytc.Text);//将单元格内容转变成Single型
if (_f < 60) {
mytc.ForeColor = System.Drawing.Color.Red;
mytc.Text = "不合格";
}
if (_f > 90) {
mytc.ForeColor = System.Drawing.Color.Green;
}
}
}
}
}
}
效果如下：
