Hi Coder,
Thank you for using syncfusion products,
First question:
Currently we don't have the support for using the custom font , we have already logged the feature request "Need add the support to use custom font in Windows phone platform". we will update you once the feature has been implemented.
Second question:
We can draw dashed line as follow,
PdfPen pen = new PdfPen(PdfBrushes.Red);
pen.DashStyle = PdfDashStyle.Dash;
page.Graphics.DrawLine(pen, new PointF(10, 10), new PointF(100, 10));
Please let us know if you need further assistance.
With Regards,
Praveen
