Hi,
I use PdfViewer for ASP.Net Web Forms to display pdf and your select to change pdf wich is displayed. To make it, I used your documentation here : https://asp.syncfusion.com/demos/web/pdfviewer/default.aspx
But when I change the pdf with this select I have an error in the console : Uncaught TypeError: Cannot read property 'load' of undefined.
It don't find 'ejpdfviewer', I don't know why.
I use this function :
function onChange(args) {
var _filename = args.value;
var _ejPdfViewer = $(#MainContent_PdfViewer2").data("ejPdfViewer");
_ejPdfViewer.load(_filename);
}
