how to bind shopping cart total value in my cart box

推荐答案

假设您具有用于显示购物车项目和价格的网格视图，则可以使用下面的代码绑定购物车总计:

Assuming you have a grid view for displaying the cart items and prices, then you can use the below code to bind shopping cart total:

decimal grdTotal = 0;

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

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
  if (e.Row.RowType == DataControlRowType.DataRow)
  {
    decimal rowTotal = Convert.ToDecimal(DataBinder.Eval(e.Row.DataItem, "price"));
    grdTotal = grdTotal + rowTotal;
  }
  lbl.Text = grdTotal.ToString("c");
}
