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")+"$"+Eval("ActionName")%>' />
</td>
<td>
<asp:LinkButton ID="btn_Del" runat="server" Text="删除" OnClientClick="return confirm('确认删除活动吗?')" CommandName="del" CommandArgument='<%#Eval("ActionId")%>' />
<a href="/Actives/ActiveCodeMgr.aspx?ActionId=<%#Eval("ActionId")%>&isedit=1">修改</a>
<a href="/Actives/ActiveCodeMgr.aspx?ActionId=<%#Eval("ActionId")%>&isshowprize=1">查看</a>
<asp:LinkButton runat="server" ID="lbAddRecycled" CommandName="add" CommandArgument='<%#Eval("ActionId") %>'>放进回收站</asp:LinkButton> <asp:LinkButton runat="server" ID="lbRemoveRecycled" CommandName="remove" CommandArgument='<%#Eval("ActionId") %>'>移出回收站</asp:LinkButton>
</td>
<td>
<asp:LinkButton ID="btn_Down" runat="server" Text="导出激活码" CommandName="download"
CommandArgument='<%#Eval("ActionId")+"$"+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);

else
{

}
}
}
}
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();
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 <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="ButtonTest.aspx.cs" Inherits="WebFormTest.TestCollect.ButtonTest" %>
