Question

如何在运行时在gridview中的Label中放置值？我想在pageload期间在gridview中的标签中放置动态值。这是我的示例代码

    private void SplitStrings()
    {
        List<string> listvalues = new List<string>();
        listvalues = (List<string>)Session["mylist"];
        string[] strvalues = listvalues.ToArray();

        if (listvalues != null)
        {
            foreach (string strElement in listvalues)
            { 
                string[] test = strElement.ToString().Split("|".ToCharArray());
                string prodQuantity = test[0].ToString();
                foreach (GridView row in gvOrderProducts.Rows)
                {
                    prodQuantity = ((Label)row.FindControl("lblQuantity")).Text;
                }
            }
        }
    }

我希望 lblQuantity 标签在我的gridview中显示数量值

Answer 1

List<double> productQty = //Filled with your quantity values
        int i = 0;
        foreach (GridViewRow row in grvProducts.Rows)
        {
            ((Label)row.FindControl("lblQuantity")).Text = productQty[i];
            i++;
        }

{
    List<string> listvalues = new List<string>();
    listvalues = (List<string>)Session["mylist"];
    string[] strvalues = listvalues.ToArray();

    if (listvalues != null)
    {
        foreach (string strElement in listvalues)
        { 
            string[] test = strElement.ToString().Split("|".ToCharArray());
            string prodQuantity = test[0].ToString();
            foreach (GridView row in gvOrderProducts.Rows)
            {
                prodQuantity = ((Label)row.FindControl("lblQuantity")).Text;
