in an asp.net page you can create controls dynamically by instantiating the object of the control class and then adding that control on the page.
e.g. To create a dynamic label use
Label l = new Label();
Page.Controls.Add(l);
This will add the control to this page.

There is 2 way to add control dynamically
One add HTML controls using string builder another on user control class object.
Ist Option
StringBuilder sb = new StringBuilder();
sb.append("<input type='text' size='20' value='' ID='text1' />");
2nd Option
TextBox txt1 = new textBox();
PlaceHolder.Controls.Add(txt1);
By this way you can add dynamic controls on your page.

Hi,
Here is a sample code
Dim lblMessage as New Label()
lblMessage.Text = "Hello, World!"
lblMessage.Font.Bold = True
'Finally, we need to add this control to the Web page. Not surprisingly, the Controls property has an Add method, which is demonstrated in the following code:
Controls.Add(lblMessage)
Thanks & Regards,
Deepika
