    I have created one C1PdfDocument Object to create pdf files.
    Now I am applying different settings to C1PdfDocument object to create customized pdf file like image, digital signature etc.

    I want to view this file before creation, because to verify how file looks after applying different settings.

    I came across PDFViewer control to view pdf file but it accepts file path means only created file can be viewed in that control.
    Is there any way to show C1PdfDocument object data in that PDFViewer window without creating file.

    Or is there any control available to fulfill my requirement?

    You can use the LoadDocument method of PDFViewer which load the Pdf from the stream. Please refer to the following documentation link:

    Yes. I know I can do it with LoadDocument Method.
    But my query is something different.

    I want to view the file before creation. I want to view C1PdfDocument Object in PDFViewer.

    Sorry for the delay!

    You can load the stream into PDFViewer using LoadDocument method. Please refer to the following lines of code:

    C1PdfDocument pdf = new C1.WPF.Pdf.C1PdfDocument();
    System.Windows.Rect rect = pdf.PageRectangle;
    rect.Inflate(-72, -72);
    Font font = new Font("Arial", 12);
    pdf.DrawString("Hello World!", font,Color.FromRgb(0,0,0), rect);
    System.IO.MemoryStream ms = new System.IO.MemoryStream();
    ms.Position = 0;

    Also, refer to the attached sample for implementing the same.
