Default RE: using Page.RenderControl()

Hi, try overriding the VerifyRenderingInServerForm method, like the following:
public override void VerifyRenderingInServerForm(Control control)
{ }
That worked for me and I hope it will help anyone that encounters this issue. Also I used a different third party component, this Word DLL written in C#, here is how you can try it out:
protected void ExportToPDF()
	System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
	System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
	string pageSoure = oStringWriter.ToString();

	DocumentModel document;
	HtmlLoadOptions option = new HtmlLoadOptions() { BaseAddress = this.Request.PhysicalApplicationPath };
	using (Stream htmlStream = new System.IO.MemoryStream(option.Encoding.GetBytes(pageSoure)))
		document = DocumentModel.Load(htmlStream, option);

	PageSetup page = document.Sections[0].PageSetup;
	page.PageWidth = 900;
	page.PageMargins.Left = 25;
	page.PageMargins.Right = 25;
	page.Orientation = Orientation.Landscape;
	page.PaperType = PaperType.A4;
	document.Save(Request.PhysicalApplicationPath + @"\temp\" + pageID.ToString() + ".pdf");
In one of my previous project I used it to convert HTML files (from various sources) into PDF files through C#. Also before showing them I needed to join these multiple files (this can also be easily done in this DLL with import method) and then export the generated PDF to an ASP.NET client.
