ASP.NET多个按钮button调用同一事件，区分是哪一button被点击

ASP.NET多个按钮button调用同一事件，区分是哪一button被点击

方法1：

 Text="删除" CommandArgument='<%#Eval("ClassID")%>' CommandName="DeletePClass1"

OnCommand="DelArrange" OnClientClick="return confirm('确定要删除该分类信息吗?');"  >

 Text="删除" CommandArgument='<%#Eval("ClassID")%>' CommandName="DeletePClass2"

OnCommand="DelArrange" OnClientClick="return confirm('确定要删除该分类信息吗?');"  >

#region 编辑

protected void EditArrange(object sender, CommandEventArgs e)

{

        string id = e.CommandArgument.ToString();
        string flag = e.CommandName;
        string sql = string.Empty;
        if (flag == "DeletePClass1")
        {
            sql = "delete tb_pclass1 where id=@id";
        }
        else if (flag == "DeletePClass2")
        {
            sql = "delete tb_pclass2 where id=@id";
        }
        else if (flag == "DeletePClass3")
        {
            sql = "delete tb_pclass3 where id=@id";
        }
        else
        {
            sql = "delete tb_pclass4 where id=@id";
        }

｝

#endregion

方法2：

Text="保存并返回" runat="server" OnClick="btn_Save">">

Text="保存并新建" runat="server" OnClick="btn_Save">

后台aspx.cs的一个事件      

    protected void btn_Save(object sender, EventArgs e)
    {

            if (((Button)sender).ID == "SaveAndBack")//关键是((Button)sender).ID 这个把sender转换成Button类型的，然后在获取按钮的ID

            {
                Response.Write("你点你的是保存并返回按钮");
            }
            else //我这里只有两个按钮不是1就是2 你根据实际情况自己变通一下if

            {
                Response.Write("你点的保存并新建按钮");
            }

   }
