Question

当我点击按钮时，我正在尝试发送object sender。

以前我的事件点击不会触发，但现在它正在制作我的代码：

 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并启动所有内容的事件：

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";

            }
        }

这里是创建的按钮开始他的活动的地方

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

如何将sender的{{1}}事件发送到DynamicButton进行更改？

我的意思是：

DButton

我需要Button Btn_clic = (Button)sender; var name = Btn_clic.Text;的事件发件人来更改此

DButton

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

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

如何创建动态按钮的事件DynamicButton，如何从DButton获取事件以发送到sender？

我的意思是

NewButton_Click

并更改来自Button Btnclick = (Button)sender; var team = Btnclick.Text; string name = Btnclick.CommandArgument;的

newButton_Click

我还在处理你的问题。但我确实让你的活动奏效了。如果这有帮助，请告诉我，我会继续提供帮助。在newButton_Click的开头放置一个断点，看它现在在这里打破了。到目前为止对互联网邮件的信用。
