获取网格行值的问题 [英] problem with getting grid row values

问题描述

我正在尝试使用此代码获取选定的网格行值，但是会发生一些错误.

I am trying to get selected grid row values using this code but some errors occur.

 protected void list_products_RowCommand(object sender, GridViewCommandEventArgs e)
{
     int RowIndex_ = int.Parse(e.CommandArgument.ToString());

     for (int i = 0; i < list_products.Rows.Count; i++)
        {
            if (RowIndex_ == i)
            {

                GridViewRow selectedRow = list_products.SelectedRow;
                product objproduct = new product();
                objproduct.userid = Convert.ToString(Session["id"]);
                this.Label5.Text = list_products.SelectedRow.Cells[2].Text;
                objproduct.productid = list_products.SelectedRow.Cells[2].Text;
                objproduct.product_name = list_products.SelectedRow.Cells[3].Text;
                objproduct.product_quantity = list_products.SelectedRow.Cells[4].Text;
                objproduct.product_type = list_products.SelectedRow.Cells[5].Text;

            }
            else
            { this.Label4.Text = "cant be select"; }
}

推荐答案

这是网格，也可以在末尾看到错误消息.编辑...
在此先感谢

错误::


错误9"System.Web.UI.WebControls.GridViewCommandEventArgs"不包含"RowIndex"的定义，并且没有扩展方法"RowIndex"接受类型为"System.Web.UI.WebControls"的第一个参数.GridViewCommandEventArgs''(您是否缺少using指令或程序集引用?)D:\ Projectz \ attendace \ Products.aspx.cs 72 64 D:\ Projectz \ attendace \

here is the grid also see the error message at the end..please also you can suggest me better solution and for updating row in inline editing...
thanks in advance

error::


Error 9 ''System.Web.UI.WebControls.GridViewCommandEventArgs'' does not contain a definition for ''RowIndex'' and no extension method ''RowIndex'' accepting a first argument of type ''System.Web.UI.WebControls.GridViewCommandEventArgs'' could be found (are you missing a using directive or an assembly reference?)
