Spire.PDFViewer Not loading new PDF

[support@atlas.us.com]

Hi,

When using Spire.PDFViewer the first PDF is loaded, but once trying to load new PDF the first one stays in the viewer. We have tried disposing, setting the viewer to null, loading a new control via run time, and it still does it.

Is there a fix to this behavior?

Hello,

Thanks for your inquiry. I have noticed the issue when using LoadFromStream to load different files and our DEV team are investigating it. On the other hand, you could use LoadFromFile to view different files in a shared folder of your web application. Please refer to the below code snippet.

Code: Select all

        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                //The interval time of emptying caching, specified in seconds.
                this.PdfViewer1.CacheInterval = 1200;
                //caching time of an image, specified in seconds.
                this.PdfViewer1.CacheTime = 1000;
                //Cache the number of Image, default is 1000.
                this.PdfViewer1.CacheNumberImage = 1000;
                //The time of responding to event after stop scrolling, specified in milliseconds.default is 500.
                this.PdfViewer1.ScrollInterval = 300;
                //Zoom value of page, default is 1.
                this.PdfViewer1.ZoomFactor = 1;
                this.PdfViewer1.CustomErrorMessages = "Error information";
                this.PdfViewer1.ScrollBars = ScrollBars.None;

                this.PdfViewer1.LoadFromFile(@"files\test1.pdf");
 
            }
        }

        protected void Button1_Click(object sender, EventArgs e)
        {

            this.PdfViewer1.LoadFromFile(@"files\test2.pdf");
        }

        protected void Button2_Click(object sender, EventArgs e)
        {
            this.PdfViewer1.LoadFromFile(@"files\test3.pdf"");
        }

Hey Simon,

Due to the nature of our application, we need it to display pdfs from a particular local path and not from the folder of the application. It was loading fine until the new spire version.

It would be helpful if you can provide us with an estimated date for it to be fixed and passed along.

Thanks,
