Question

我创建动态按钮，我正在尝试使用FindControll来避免多个ID，我将ID分配给UpdatePanel的触发器，但这总是说是null，当我按下按钮并使循环创建按钮并将id（动态地）分配给触发器。这总是说是重复的

这是我正在使用的代码：

protected void DynamicButton()
    {
        //BAD TOOLS INTO THE LIST AND SHOW
        List.ListUsers listsArea = new List.ListUsers();
        List<Data.Area> Area = listsArea.AreaList();

        List<Data.Area> ListOfEquiposNoOk = Area.Where(x => x.AREA == "ENG" && x.STANDBY == 1).ToList();

        List<Button> BotonesBad = new List<Button>();

        List<Data.Area> ListOfEquiposOk = Area.Where(x => x.AREA == "ENG" && x.STANDBY == 0).ToList();

        List<Button> Botones = new List<Button>();

        var TeamGood = ListOfEquiposOk.Select(x => x.TEAM).Distinct().ToList();
        foreach (var team in TeamGood)
        {
            AsyncPostBackTrigger trigger = new AsyncPostBackTrigger();
            UpdatePanel Update = (UpdatePanel)Master.FindControl("BtnG_" + team);
            Button newButtonGood = new Button();
            Control controlGoodID = FindControl("BtnG_" + team;);
            if (controlGoodID == null && controlGoodID == null)
            {
                newButtonGood.CommandName = "Btn" + team;
                newButtonGood.Text = team;
                newButtonGood.CommandArgument = "ENG";
                newButtonGood.ID = "BtnG_" + team;

                trigger.ControlID = newButtonGood.ID;
                trigger.EventName = "Click";
                UpdatePanel4.Triggers.Add(trigger);

                newButtonGood.Click += new EventHandler(Button1_Click);

                Good.Controls.Add(newButtonGood);

                newButtonGood.CssClass = "btn-primary outline separate";
            }
            else
            {
                Botones = Good.Controls.OfType<Button>().ToList();
                Botones.Add(newButtonGood);
            }
        }
    }

这是我在动态按钮上输入的HTML，以及我在尝试将id分配给trigger

的地方

<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
            <ContentTemplate>
                <div id="tools_info" role="dialog">
                    <div class="modal-dialog modal-sm" style="width: 450px">
                        <div class="modal-content">
                            <h2>&nbsp Tools information</h2>
                            <br />
                            <ul class="nav nav-tabs">
                                <li><a data-toggle="tab" href="#good">Good Condition</a></li>
                                <li><a data-toggle="tab" href="#bad">Bad Condition</a></li>
                            </ul>
                            <br />
                            <div id="good" class="tab-pane fade in active">
                                <asp:UpdatePanel runat="server" ID="UpdatePanel2">
                                    <ContentTemplate>
                                        <asp:Panel runat="server" ID="Good">
                                            <asp:TextBox ID="TextBoxA1" runat="server" Visible="False"></asp:TextBox>
                                        </asp:Panel>
                                    </ContentTemplate>
                                </asp:UpdatePanel>
                            </div>
                        </div>
                    </div>
                </div>
            </ContentTemplate>
            <Triggers>
            </Triggers>
        </asp:UpdatePanel>

如何使用FindControl
