復制代碼 代碼如下:

//動態生成三個控件
protected void Button1_Click(object sender, EventArgs e)
{
for (int i = 0; i < 3; i++)
{
TextBox t = new TextBox();
t.ID = string.Format("newTextBox{0}",i);
Panel1.Controls.Add(t);
}
ListControlsInPanel();
}

復制代碼 代碼如下:

//獲取動態生成的控件的值
protected void Button3_Click(object sender, EventArgs e)
{
string str="";
string[] ak = Request.Form.AllKeys;
for (int i = 0; i < Request.Form.Count; i++)
{
//只篩選出動態生成的三個控件的值
if(ak[i].IndexOf ("new")>-1)
str += string.Format("<li>{0}</li><br>",Request .Form [i]);
}
Label1.Text = str;
}
