显示 HTML 动态按钮

Question

我正在尝试在 c# 中生成动态 html 按钮，但是当我运行代码时正在生成按钮。我正在尝试以两种不同的方式生成动态按钮，但没有一种方法适合我。如果代码有任何问题，请告诉我。我在 page _Load 和 page_init 事件中尝试过。这是我正在使用的代码......

protected void page_Init(object sender, EventArgs e)

{             

    Table tblControls = new Table();

    TableRow trControl1 = new TableRow();

    TableCell tdControl1 = new TableCell();

    tdControl1.Text = "<input id='Submit" + "' runat='server' type='button' value='Submit' onclick='alert('Yahooooo');' onserverclick='Submit_Click'></input>";

    trControl1.Cells.Add(tdControl1);                   

    tblControls.Rows.Add(trControl1);





    int i = 1;

    string strMessage = "hi";

    HtmlButton htmSubmit = new HtmlButton(); 

    htmSubmit.ID = "Submit" + i; 

    htmSubmit.InnerHtml = "Submit";



    htmSubmit.Attributes.Add("onclick", "alert('Yahoooooo');");





    htmSubmit.Attributes.Add("GuestId", "GuestUserId" + i.ToString()); 

    htmSubmit.Attributes.Add("UserId", "UserId" + i.ToString()); 

    htmSubmit.Attributes.Add("Message", strMessage); 

    htmSubmit.ServerClick += new System.EventHandler(this.Submit_Click);

}





protected void Submit_Click(object sender, EventArgs e)

{

    HtmlButton btn = (HtmlButton)sender; 

    string strGuestUserId = btn.Attributes["GuestId"]; 

    string strUserId = btn.Attributes["UserId"]; 

    string strMessage = btn.Attributes["Message"]; 

    Response.Write("Your have clicked " + btn.ID.ToString() + "<br/>" + strGuestUserId + "<br/>" + strUserId + "<br/>" + strMessage);

}

看起来您缺少将 tblControls 添加到 Page.Controls 集合的语句。您可能还打算将动态按钮添加到 tdControl1 控件中。
