将新事件添加到按钮(add new event to button)

将新事件添加到按钮(add new event to button) protected void Page_Load(object sender, EventArgs e) { Button a = new Button(); a.Width = 100; a.Height = 100; a.Text = "one"; a.Click += new EventHandler(test); form1.Controls.Add(a); } protected void test(object sender, EventArgs e) { Button b = new Button(); b.Width = 100; b.Height = 100; b.Text = "two"; b.Click += new EventHandler(test2); form1.Controls.Add(b ); Response.Write("aaaaaaaaaaaaaaaaaa"); } protected void test2(object sender, EventArgs e) { Response.Write("bbbbbbbbbbbbbbb"); }

当点击one显示按钮two但是当点击two按钮时不运行test2 ???? 点击two页刷新时。

我想首先点击'one'，然后'two'只在点击按钮a后显示按钮

protected void Page_Load(object sender, EventArgs e) { Button a = new Button(); a.Width = 100; a.Height = 100; a.Text = "one"; a.Click += new EventHandler(test); form1.Controls.Add(a); } protected void test(object sender, EventArgs e) { Button b = new Button(); b.Width = 100; b.Height = 100; b.Text = "two"; b.Click += new EventHandler(test2); form1.Controls.Add(b ); Response.Write("aaaaaaaaaaaaaaaaaa"); } protected void test2(object sender, EventArgs e) { Response.Write("bbbbbbbbbbbbbbb"); }

when click on one show Button two but when click on twobutton does not run test2???? when click on two page refresh.

i want first click on 'one' and then 'two' show the button only after button a has been clicked

最满意答案

尝试这个：

protected void Page_Init(object sender, EventArgs e) { Button a = new Button(); a.Width = 100; a.Height = 100; a.Text = "one"; a.Click += new EventHandler(test); form1.Controls.Add(a); Button b = new Button(); b.Visible = false; b.Width = 100; b.Height = 100; b.Text = "two"; b.Click += new EventHandler(test2); form1.Controls.Add(b); } protected void test(object sender, EventArgs e) { b.Visible = true; Response.Write("aaaaaaaaaaaaaaaaaa"); } protected void test2(object sender, EventArgs e) { Response.Write("bbbbbbbbbbbbbbb"); }

Try this:

protected void Page_Init(object sender, EventArgs e) { Button a = new Button(); a.Width = 100; a.Height = 100; a.Text = "one"; a.Click += new EventHandler(test); form1.Controls.Add(a); Button b = new Button(); b.Visible = false; b.Width = 100; b.Height = 100; b.Text = "two"; b.Click += new EventHandler(test2); form1.Controls.Add(b); } protected void test(object sender, EventArgs e) { b.Visible = true; Response.Write("aaaaaaaaaaaaaaaaaa"); } protected void test2(object sender, EventArgs e) { Response.Write("bbbbbbbbbbbbbbb"); }
