pdfDocumentViewer page Size control(fit)

[kelesym]

How can i make fit page width size to control width size? I want this to work dynamically with form(or control).

Thank you.

+ What is the difference between PdfViewer and PdfDocumnetViewer?

Hello,

Thanks for your inquiry. Please refer to the below code snippet to make the page width fit to the control width.

Code: Select all

            float controlWidth = this.pdfDocumentViewer1.Width; 
            float pageWidth = 815;
            float rate = controlWidth / pageWidth*100;
            var result = rate.ToString("#0");
            int percentage = int.Parse(result);
            this.pdfDocumentViewer1.ZoomTo(percentage);

The difference between PdfDocumnetViewer and PdfViewer is that PdfDocumnetViewer supports customized design and PdfViewer doesn't, it's not allowed to modify.

Thanks! I found another method! //ZoomTo(Spire.PdfViewer.Forms.ZoomMode.FitWidth);
