Adding Controls at runtime ?

You could add them at that page load or event handlers of buttons, check
boxes etc. whenever needed.

Add them in the form object:
HtmlForm f =Page.FindControl("form1");
f.Controls.Add(<Control>);

what's the best way to add (web)controls at runtime ??
Add them to the Controls collection of the parent object. Here is a
simple example of how you can add a Label control to the web form.

C#:
Label message=new Label();
message.Text="Hello World!";
Controls.Add(message);

VB.NET:
Dim message As New Label()
message.Text="Hello World!"
Controls.Add(message)

How can I do that with a textbox, I'll get an error saying there must
be positioned in a formtag with runat = "server", but where if I
generate in at runtime??

You'll have to add it to the HtmlForm control. The following C# code
will add a textbox to the form:
TextBox tbx=new TextBox();
tbx.Text="Hello";
Page.FindControl("Form1").Controls.Add(tbx);

Great, one last question, is the a chance to directly insert XML-Data
to that textbox ?

The Text property of the TextBox hold the value displayed in the
textbox. Just assign the XML string to this property. If you have an
XmlDocument instance holding the XML data you can do this to display the
entire XML document in the TextBox:

myTextBox.Text=myXmlDocument.DocumentElement.OuterXml;

Sorry my fault,

ich don't mean the whole XML document, but only dataparts of it

i.E.

a very smple xml.file

<Name>Peter</Name>

The nametag should be inserted in a label and the content into a
textbox
