用户遵循的方式.

Hi,

User following way.

Button btn = new Button();
btn.Click += 

在上面的代码中，执行+ =后，您将看到选项卡的工具提示消息.

In above code after doing += you will see tooltip message for tab.

尝试此操作

公共局部类TempFunction:System.Web.UI.Page
{
TextBox txt =新的TextBox();
Button btn = new Button();
标签lbl = new Label();
受保护的void Page_Load(对象发送者，EventArgs e)
{

lbl.Text =输入文字:";
lbl.Font.Bold = true;

this.Form.Controls.Add(lbl);
this.Form.Controls.Add(txt);
txt.Text ="Hello World";
btn.Text ="btnsave";
btn.Attributes.Add("runat"，"server");
this.Form.Controls.Add(btn);
btn.Click + = new System.EventHandler(this.Button_Click);
}

受保护的void Button_Click(对象发送者，EventArgs e)
{
txt.Text =更改";
}

try this

public partial class TempFunction : System.Web.UI.Page
{
TextBox txt = new TextBox();
Button btn = new Button();
Label lbl = new Label();
protected void Page_Load(object sender, EventArgs e)
{

lbl.Text = "Enter Text : ";
lbl.Font.Bold = true;

this.Form.Controls.Add(lbl);
this.Form.Controls.Add(txt);
txt.Text = "Hello World";
btn.Text = "btnsave";
btn.Attributes.Add("runat", "server");
this.Form.Controls.Add(btn);
btn.Click += new System.EventHandler(this.Button_Click);
}

protected void Button_Click(object sender, EventArgs e)
{
txt.Text = "Change";
}
