求助求助：gridView中RowCommand事件 的问题

Question

红色是错误 处，应该怎么改正？急急。。
protected void GVdetail_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        if (e.CommandName == "AddToBus")
        {
            string petID = this.GVdetail.DataKeys[e.Row.RowIndex].ToString();         
           if (Session["bus"] == null)
            {
                System.Collections.Hashtable ht = new Hashtable();                ht.Add(petID, 1);
                Session["bus"] = ht;
               // Session.Add("bus", ht);
            }
            else 
            {System.Collections .Hashtable ht=(Hashtable )Session ["bus"];
            if (ht[petID] == null)
            {
                ht[petID] = 1;
            }            else
            {
                ht[petID] = (int)ht[petID] + 1;
            }            Session["bus"] = ht;
            }
        }    }
错误 1 “System.Web.UI.WebControls.GridViewCommandEventArgs”并不包含“Row”的定义

Answer 1

试试: Button btn = (Button)sender;
        GridViewRow gvr = (GridViewRow)btn.Parent.Parent;
        string pk = GVdetail.DataKeys[gvr.RowIndex].Value.ToString();

Answer 2

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
int rowIndex = int.Parse(e.CommandArgument.ToString());
}

Answer 3

<asp:TemplateField ShowHeader="False">
     <ItemTemplate>
        <asp:Button ID="Button1" runat="server" CausesValidation="false" CommandName="Fuck" Text="Test" CommandArgument='<%# Container.DisplayIndex %>' />
     </ItemTemplate>
</asp:TemplateField>protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
        if (e.CommandName == "Fuck")
        {
            Response.Write(string.Format("{0}", GridView1.DataKeys[Convert.ToInt32(e.CommandArgument)].Value));
        }
}

Answer 4

string petID = this.GVdetail.DataKeys[e.Row.RowIndex].ToString();   
少了个.value()!!!!        

Answer 5

 protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        if (e.CommandName == "aaa")
        {
            string id = GridView1.DataKeys[e.CommandArgument].ToString();
        }    }你的那个控件里面的必须绑定你要得到的id;<asp:GridView ID="GridView1" runat="server" OnRowCommand="GridView1_RowCommand">
    <Columns>
        <asp:TemplateField>
            <ItemTemplate>
                <asp:Button ID="Button1" runat="server" Text="Button" CommandName="aaa" CommandArgument='<%#Eval("Id") %>' />
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
    </asp:GridView>   

Answer 6

综合 了一下，成功了！string petID = this.GVdetail.DataKeys[Convert.ToInt32(e.CommandArgument)].Value.ToString ();

Answer 7

 把红的那点换成下面的代码
int index=Convert.ToInt32(e.CommandArgument);
DataKey key=this.GridView1.DataKeys[index];
string petID =key.value.ToString();
