Hi,
Can you try to isolate the problem into a test page and post the test page? Once we have that we will take a look and see what we can find.
Thanks!

CODE BEHIND PAGE****************
protected void btnSubmit_Click(object sender, EventArgs e)
{
EO.Pdf.Runtime.AddLicense("*dummy***");
EO.Pdf.HtmlToPdf.Options.MinLoadWaitTime = 5000;
ASPXToPDF1.RenderAsPDF("test.pdf");
}
I can see chart rendereing completely in my aspx page but when I generate PDF it shows only chart area (not bars).
Thanks

Hi,
Please try to isolate the problem into a working test page so that we can try to run it here to reproduce problem.
Thanks!

Hi - I was able to fix this problem by setting viewstate of the asp.net chart control to true.
What actually happens that when I click the button it postbacks page and viewstate being false won't allow chart to be shown in the PDF.
Unlike other .net controls, the viewstate property of chart control is set to false by default .
Enabling viewstate property to true solved the problem.
Thanks

Hi,
Glad that you got it working. ASPXToPDF does not require ViewState to function. You can try to think ASPXToPDF as an output redirector: If you comment out RenderAsPDF call in your btnSubmit_Click event and the chart displays correctly on screen, then it should display fine when you call RenderAsPDF.
Thanks!
