How to show the same opened window again

[Prabakaran]

Dear Team,

If the doc is open for the first time, a new doc window will open and if the same doc is open again, the existing window should be set active. Currently keep opening new windows instead show already opened window. How can i achieve this. please advise.

var openwindow = new PDFViewerWindow();
                                  openwindow.Show();
                                  openwindow.pdfViewer.DocumentSource =
                                      new PdfDocumentSource(new Uri(uri, UriKind.RelativeOrAbsolute));

Thank you.

Regards,

Prabakaran

Hello Prabakaran,

You could implement something like caching to keep the information about the corresponding window for each document and set the desired window as active when needed. You may find helpful to check this reply on StackOverflow, which concerns a scenario similar to this one.
