问个GridView改变列值的问题

[wylovemzc]

protected void Page_Load(object sender, EventArgs e)
{
try
{
string sql = "select SurveyID,SurveyDate,SurveyProject,SurveyCPI,SurveyLength,SurveyMemo,SurveyStatus from survey";
con = new SqlConnection(connstr);
con.Open();
SqlCommand com = new SqlCommand(sql, con);
SqlDataReader read = com.ExecuteReader();
while (read.Read())
{
SurveyID = read["SurveyID"].ToString();
SurveyDate = read["SurveyDate"].ToString();
SurveyProject = read["SurveyProject"].ToString();
SurveyCPI = read["SurveyCPI"].ToString();
SurveyLength = read["SurveyLength"].ToString();
SurveyMemo = read["SurveyMemo"].ToString();
SurveyStatus = read["SurveyStatus"].ToString();
string sql1 = "select * from surveylog where Username='wangyi1687' and SurveyID='" + SurveyID + "'";
con = new SqlConnection(connstr);
con.Open();
SqlCommand com1 = new SqlCommand(sql1, con);
SqlDataReader reader = com1.ExecuteReader();
if (reader.Read())
{
SurveyStatus2 = reader["SurveyStatus"].ToString();
con = new SqlConnection(connstr);
string sql2 = "select * from survey where SurveyID='" + SurveyID + "'";
//创建SqlDataAdapter对象,调用sql
SqlDataAdapter myadapter = new SqlDataAdapter(sql2, con);
//创建并填充DataSet
myadapter.Fill(ds);
GridView1.DataSource = ds;
GridView1.DataBind();
con.Close();
}
}
}
catch (Exception ex)
{
ex.ToString();
}
}
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
if (SurveyStatus2 == "有效")
{
e.Row.Cells[6].Text = "<a href=CategoryInfoInfo.aspx?SurveyID=" + SurveyID + ">有效</a>";
}
else
{
e.Row.Cells[6].Text = SurveyStatus2;
}
}
}

现在的问题是，如果判断出来的SurveyStatus2是有效，那么就把另外的那条数据给覆盖了，而且RowDataBound事件里执行了2次if (SurveyStatus2 == "有效")

你现在的数据是否有两天记录？

GridView1_RowDataBound事件是每次绑定行的时候都会触发的

[奔跑的蜗牛007]

页面装载事件表明,每回调一次,就重新绑定业次,如果你在表格上进行操作,那肯定要回调一次再执行对应的事件一次,加起来应是二次

是不是要调整这个列的宽度啊。
GridView1_RowDataBound 每行会进一次。

那么就把另外的那条数据给覆盖了

另外的那條數據是什么數據？聽不明白。
