如何获取对象发件人？

Question

单击按钮时，我正在尝试发送object sender 。

以前，我的事件点击不会触发，但现在它使我的代码如下：

 public partial class Dashboard : System.Web.UI.Page
    {
        static bool enable = false;

        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                DynamicButton();
            }
            else if(enable)
            {
                DynamicButton();
            }    
        }

这是更改DynamicButton并启动所有操作的事件：

protected void DButton(object sender, EventArgs e)
        {
            ScriptManager.RegisterStartupScript(this, this.GetType(), "Pop", "showAndHide();", true);

            enable = true;
            DynamicButton();
        }

这是我开始创建动态按钮的地方：

protected void DynamicButton()
        {
            List.ListUsers listArea = new List.ListUsers();
            List<Data.Area> Area = listArea.AreaList();

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

            var TeamFCH = ListOfEquiposOk.Select(x => x.TEAM).Distinct().ToList();

            foreach (var team in TeamFCH)
            {
                LinkButton newButton = new LinkButton();
                newButton.CommandName = "Btn" + Convert.ToString(team);
                newButton.ID = "Btn_" + Convert.ToString(team);
                newButton.Text = team;
                newButton.CommandArgument = "ENG";

                newButton.Click += new EventHandler(newButton_Click);

                pan1.Controls.Add(newButton);

                newButton.CssClass = "btn-primary outline separate";

            }
        }

这是创建的按钮开始其事件的位置

protected void newButton_Click(object sender, EventArgs e)
        {
            ScriptManager.RegisterStartupScript(this, this.GetType(), "Pop", "ModalGood();", true);
            List.ListUsers listArea = new List.ListUsers();
            List<Data.Area> Area = listArea.AreaList();

            List<Data.Area> ListOfToolsOk = Area.Where(x => x.AREA == "ENG" && x.TEAM == "516" && x.STANDBY == 0).ToList();

            var ToolArea = ListOfToolsOk.Select(x => x.TEAM);
            Grv_Eng.DataSource = ListOfToolsOk;
            Grv_Eng.DataBind();
        }

我的问题是

如何获取DButton的事件sender以发送到DynamicButton进行更改？

我的意思是：

Button Btn_clic = (Button)sender;
var name = Btn_clic.Text;

我需要DButton的事件发送者来更改此设置

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

newButton.CommandArgument = CHANGE THIS -> "ENG";

这些来自DynamicButton

以及如何获取创建的动态按钮的事件sender ，以及如何从DButton获取事件并将其发送到NewButton_Click ？

我也是

Button Btnclick = (Button)sender;
var team = Btnclick.Text;
string name = Btnclick.CommandArgument;

并更改来自newButton_Click此newButton_Click ：

List<Data.Area> ListOfToolsOk = Area.Where(x => x.AREA == CHANGE THIS -> "ENG" && x.TEAM == CHANGE THIS -> "516" && x.STANDBY == 0).ToList();

我仍在努力解决您的问题。 但是我确实让您的活动上班了。 请告诉我是否有帮助，我会继续提供帮助。 在newButton_Click的开头放置一个断点，看看它现在在这里断了。 到目前为止，已记入互联网帖子。
