protected void gvTest_RowDataBound(object sender, GridViewRowEventArgs e)
{
    //如果是绑定数据行
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        //鼠标经过时，行背景色变
        e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='#E6F5FA'");
        //鼠标移出时，行背景色变
        e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='#FFFFFF'");
        //为gridview行添加双击事件
        string url = "http://www.baidu.com/";
        e.Row.Attributes.Add("ondblclick", "javascript:parent.location.href='"+url+"'");
        //为gridview列添加click事件
        e.Row.Cells[3].Attributes.Add("onclick", "javascript:parent.location.href='" + url + "'");
    }
    //如果是绑定数据行
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        if (e.Row.RowState == DataControlRowState.Normal || e.Row.RowState == DataControlRowState.Alternate)
        {
            //删除前弹出确认框
            ((LinkButton)e.Row.Cells[6].Controls[0]).Attributes.Add("onclick", "javascript:return confirm('你确认要删除：\"" + e.Row.Cells[2].Text + "\"吗?')");
        }
    }
    if (e.Row.RowIndex != -1)//自动生成编码列
    {
        int id = e.Row.RowIndex + 1;
        e.Row.Cells[0].Text = id.ToString();
    }
    if (e.Row.RowIndex != -1)//过长的内容，用...代替
    {
        string strInfo = e.Row.Cells[2].Text;
        e.Row.Cells[2].Text = SubStr(strInfo, 1);
        e.Row.Cells[2].ToolTip = strInfo;
    }
    if (e.Row.RowIndex == 5)//突出显示某信息
    {
        e.Row.Cells[0].BackColor = System.Drawing.Color.Red;
    }
}
public string SubStr(string sString, int nLeng)
{
    if (sString.Length <= nLeng)
    {
        return sString;
    }
    string sNewStr = sString.Substring(0, nLeng);
    sNewStr = sNewStr + "...";
    return sNewStr;
