Hi, I am trying to silently save the pdf on the server on button click but get the following error at " ASPXToPDF1.RenderAsPDF(false);" while debugging:

"Value cannot be null.
Parameter name: type "

It generates pdf on the client successfully but when I try to save it silently, it gives error mentioned above.

Following is my code snippet:


protected void btnSubmit_Click(object sender, EventArgs e)
{
EO.Pdf.Runtime.AddLicense("****");
EO.Pdf.HtmlToPdf.Options.PageSize = new System.Drawing.SizeF(11F, 8.5F);// landscape
EO.Pdf.HtmlToPdf.Options.OutputArea = new System.Drawing.RectangleF(0.5f, 0.5f, 10f, 10f); // margins
EO.Pdf.HtmlToPdf.Options.MinLoadWaitTime = 5000;
ASPXToPDF1.RenderAsPDF(false);
//Cast the Result property to HtmlToPdfResult
HtmlToPdfResult result = (HtmlToPdfResult)ASPXToPDF1.Result;
//Save the conversion result to a file
result.PdfDocument.Save(Server.MapPath("test.pdf"));
}


Please help. Thanks.
