各位高手帮忙看下这段代码哪里有错。。绑定的GRIDVIEW没有显视出来。没有提示代码有错

[congc1212]

private void SetBind()
{
string conntext = (ConfigurationManager.ConnectionStrings["ConnectionString"]).ToString();
SqlConnection conn = new SqlConnection(conntext);
conn.Open();
string sql="SELECT FlightNO,BillNO,ReceiveTicket FROM Positioning";
SqlDataAdapter da = new SqlDataAdapter(sql,conn);
DataSet ds = new DataSet();
da.Fill(ds);
GridView1.DataSource = ds;
GridView1.DataBind();

}

Page_load里面有没调用该方法

[congc1212]

还是不行

你在此方法里任何地方加上断点看是否运行到这里的代码了吗????

[slove1116]

AutoGenerateColumns=true

AutoGenerateColumns=true

SetBind() 方法在放在Page_load?

protected void Page_Load(object sender, EventArgs e)
    {
     SetBind() ;
     }

[diertiantang]

把你的代码照如下来改

protected void Page_Load(object sender, EventArgs e)
{
SetBind() ;
}



private void SetBind()
{
string conntext = (ConfigurationManager.ConnectionStrings["ConnectionString"]).ToString();
SqlConnection conn = new SqlConnection(conntext);
conn.Open();
string sql="SELECT FlightNO,BillNO,ReceiveTicket FROM Positioning";
SqlDataAdapter da = new SqlDataAdapter(sql,conn);
DataSet ds = new DataSet();
da.Fill(ds);
DataTable dt;
dt=ds.Tables[0];
GridView1.DataSource = dt;
GridView1.DataBind();

}

[takako_mu]

GridView1.DataSource = ds.Tables[0];

[幕夜]

private void SetBind()
{
string conntext = (ConfigurationManager.ConnectionStrings["ConnectionString"]).ToString();
SqlConnection conn = new SqlConnection(conntext);
conn.Open();
string sql="SELECT FlightNO,BillNO,ReceiveTicket FROM Positioning";
SqlCommand cmd = new SqlCommand(sql,con);
SqlDataAdapter da = new SqlDataAdapter();
da.SelectCommand = cmd;
DataSet ds = new DataSet();
da.Fill(ds);
GridView1.DataSource = ds;
GridView1.DataBind();

}
应该是这样吧！
