在C#.Net中在面板内动态创建表

这是我的密码

   protected void Button1_Click(object sender, EventArgs e)
    {
        Panel panel1 = new Panel();
        Label newLabel = new Label();
        newLabel.ID = "lbltest";
        newLabel.Text = "my new label..";
        panel1.Controls.Add(newLabel);
    }

单击按钮时，我看不到“我的标签”文本

有什么帮助吗

您必须将面板添加到页面上存在的任何控件中。

您必须将面板添加到页面上存在的任何控件中。

如果您没有其他地方可以放置面板，您必须将面板添加到网页或顶级表单元素中的某个控件中

protected void Button1_Click(object sender, EventArgs e)
{
    Panel panel1 = new Panel();
    Label newLabel = new Label();
    newLabel.ID = "lbltest";
    newLabel.Text = "my new label..";
    panel1.Controls.Add(newLabel);
    this.Form.Controls.Add(panel1); // YOU ARE MISSING THIS
}
