ASP.NET中Button控件的CommandName和CommandArgument属性用法

在Repeater中的使用：

            <asp:Repeater ID="rptActionList" runat="server" OnItemCommand="rptActionList_ItemCommand" OnItemDataBound="rptActionList_DataBinding">

                <ItemTemplate>

                    <tr class="info">

                        <td>

                            <%#Eval("ActionName") %>

                        </td>

                        <td>

                             <asp:LinkButton ID="btn_Down_Exchanged" runat="server" Text="下载" CommandName="downloadExchanged"

                                CommandArgument='<%#Eval("ActionId")+"$"+Eval("ActionName")%>' />

                        </td>

                        <td>

                            <asp:LinkButton ID="btn_Del" runat="server" Text="删除" OnClientClick="return confirm('确认删除活动吗?')" CommandName="del" CommandArgument='<%#Eval("ActionId")%>' />&nbsp;&nbsp;
                            <a href="/Actives/ActiveCodeMgr.aspx?ActionId=<%#Eval("ActionId")%>&isedit=1">修改</a> &nbsp;&nbsp;
                            <a href="/Actives/ActiveCodeMgr.aspx?ActionId=<%#Eval("ActionId")%>&isshowprize=1">查看</a>&nbsp;&nbsp;
                            <asp:LinkButton runat="server" ID="lbAddRecycled" CommandName="add" CommandArgument='<%#Eval("ActionId") %>'>放进回收站</asp:LinkButton>

                            <asp:LinkButton runat="server" ID="lbRemoveRecycled" CommandName="remove" CommandArgument='<%#Eval("ActionId") %>'>移出回收站</asp:LinkButton>

                        </td>

                        <td>

                            <asp:LinkButton ID="btn_Down" runat="server" Text="导出激活码" CommandName="download" CommandArgument='<%#Eval("ActionId")+"$"+Eval("ActionName")%>' />

                        </td>

                    </tr>

                </ItemTemplate>

            </asp:Repeater>

        protected void rptActionList_ItemCommand(object source, RepeaterCommandEventArgs e)

        {

            if (e.CommandName.ToString() == "del") //通过判断CommandName来区分执行什么操作

            {

                int ActionId = int.Parse(e.CommandArgument.ToString());

                if (ActionId > 0)

                {

                    int ret = activeCodeNewMgr.DelAction(ActionId);

                    if (ret != Const.SUCCESS)

                    {

                        LogHelper.Error("活动删除失败:ActionId:" + ActionId);

                    }

                    else

                    {

                        BindData();

                    }

                }

            }

            else if (e.CommandName.ToString() == "download")

            {

                string[] args = e.CommandArgument.ToString().Split('$');

                int _ActionId = int.Parse(args[0]);

                if (_ActionId > 0)

                {

                    List<ActivationInfo> list = activeCodeNewMgr.GetActivationByActionId(_ActionId, 0, 1, 500000);

                    string _actionName = string.Empty;

                    if (args.Length > 1) _actionName = args[1];

                    this.DownLoadActvation(list, _actionName);

                }

                else

                {

                    JSAlert("活动不存在!!");

                }

            }

            else if (e.CommandName == "add")

            {

                int actionId = Convert.ToInt32(e.CommandArgument);

                activeCodeNewMgr.ChangedActivety(1, actionId);

                this.BindData();

            }

            else if (e.CommandName == "remove")

            {

                int actionId = Convert.ToInt32(e.CommandArgument);

                activeCodeNewMgr.ChangedActivety(0, actionId);

                this.BindData();

            }

            else if (e.CommandName == "downloadExchanged")

            {

                string[] args = e.CommandArgument.ToString().Split('$');

                int _ActionId = int.Parse(args[0]);

                int count = 0;

                if (_ActionId > 0)

                {

                    List<ActivationInfo> list = activeCodeNewMgr.GetActioncodeExchanged(_ActionId, out count);

                    if (list != null && list.Count > 0)

                    {

                        foreach (ActivationInfo ai in list)

                        {

                            UserProfile userInfo = new UserProfile();

                            userInfo.getUserInfo(ai.UserId);

                            ai.NickName = userInfo.UserNickName;

                        }

                    }



                    string _actionName = string.Empty;

                    if (args.Length > 1) _actionName = args[1];

                    this.DownLoadActionCodeExchanged(list, _actionName);

                }

                else

                {

                    JSAlert("活动不存在!!");

                }

            }

        }

 

另外的用法：让点击不同按钮的事件共用一个，通过判断CommandName和CommandArgument来区分
