another try:
during the oninit I add the control in the page, then I render this control
only later, but in this case the error is:
Control 'ctl00_MainContent_MyControl_FormView1' of type 'FormView' must be
placed inside a form tag with runat=server.
The rendering process of the formview verify that the control is correctly
created in a page.
Can I create a page in memory???

allready tried, and this cause another error
which is:
The RegisterRequiresViewStateEncryption() method needs to be called before
or during Page_PreRender.
when I try to add the control in the placeholder.

RenderControl() then remove it :)
somePlaceHolder.Controls.Add(ctl);
ctl.DataBind();
ctl.RenderControl(htmlTExtWriter);
somePlaceHolder.Controls.Remove(ctl);
where somePlaceHolder is just an <asp:placeholder control inside a form.

And I want to render the result into a string.

StringBuilder stringBuilder = new StringBuilder();
StringWriter stringWriter;
HtmlTextWriter htmlTextWriter;
stringWriter = new StringWriter(stringBuilder);
htmlTextWriter = new HtmlTextWriter(stringWriter);
ctl = Page.LoadControl("~/controls/Overview.ascx");
.... some commands here ....
ctl.DataBind();
ctl.RenderControl(htmlTextWriter);
return stringBuilder.ToString();
