 {

 DataTable dt = new DataTable（）; 
 
 
 dt =（DataTable）会话[bestStocks];

 BestStockslb.DataBind（）; 
} 
} 
}

解决方案

似乎你已经忘记了DataTextField和DataValueField

  dt =（DataTable）Session [ bestStocks]; 
 
 DataView dv = new DataView（dt）; 
 BestStockslb.DataSource = dt; 
 BestStockslb.DataTextField =Name; 
 BestStockslb.DataValueField =ID; 
 BestStockslb.DataBind（）; 
  

I have a session object that contains a DataTable from my previous page, and i would like to bind this DataTable to a ListBox.

I'v done this:

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        if (Session["bestStocks"] !=null)
        {
            DataTable dt = new DataTable();


            dt = (DataTable)Session["bestStocks"];

            DataView dv = new DataView(dt);
            BestStockslb.DataSource = dt;
            BestStockslb.DataBind();
        }
     }
 }

I get this result:

Any suggestion?

解决方案

It seems you have forgot the DataTextField and DataValueField

 dt = (DataTable)Session["bestStocks"];

DataView dv = new DataView(dt);
BestStockslb.DataSource = dt;
BestStockslb.DataTextField =  "Name";
BestStockslb.DataValueField =  "ID"; 
BestStockslb.DataBind();
