按钮点击事件你可以写：

System.Web.UI.WebControls.Label myLabel = new Label（ ）;

myLabel.Text =" Sample Label";

Form1.Controls.Add（myLabel）;


系统.Web.UI.WebControls.TextBox myTextBox = new TextBox（）;

myTextBox.ID =" TextBox1";

myTextBox.Text =" Hi" ;; < br $>
Form1.Controls.Add（myTextBox）;


-Ankit

On button click event you can write:

System.Web.UI.WebControls.Label myLabel = new Label();
myLabel.Text = "Sample Label";
Form1.Controls.Add(myLabel);

System.Web.UI.WebControls.TextBox myTextBox = new TextBox();
myTextBox.ID = "TextBox1";
myTextBox.Text="Hi";
Form1.Controls.Add(myTextBox);

-Ankit

感谢Ankit的想法..但是问题是，当我点击按钮时，会出现一个文本框，询问文本框控件的数量。如果我给5，那么5个文本框; s应该出现要求标签&当我点击提交按钮时，


5标签盒带有给定的标签&相应的5个文本框; s将出现

那么我应该如何编码循环？为此。


请帮助...

Thanks Ankit for the idea..But the problem is,when i click the button,a textbox will appear asking for "number of textbox controls".so if i give 5,then 5 text box;s should appear asking for labels & when i click the button "submit",the

5 labelbox''s with the given labels & corresponding 5 textbox;s will appear
So how should i code the "loop" for this.

please help...
