After I download a file, I want to save it (blob or filestream) to cache similar to savetocache.
How can I do it without a viewer control?

Hello,

Apologies for taking so long to get back to you. Could you elaborate on what you mean by "After I download a file"? Is this with regards to our HTML5 Document SDK or our .NET Document SDK? Any/all of the Document SDK (both HTML5 and .NET) functionality can be achieved without the use of the Document Viewer control. Generally this involves using commands from the DocumentFactory, or the LEADDocument its self.

Thanks,

HTML5Demos.DriveHelper.LTSharePoint.SharePointService.downloadFile(tempProperties, "file.pdf")
.done(function (base64) {
var data = lt.LTHelper.base64DecodeToByteArray(base64);
var byteArray = new Uint8Array(data);
var file = new HTML5Demos.DriveHelper.DriveFile(fileName[0]);
file.fileBlob = new Blob([byteArray]);
var args = new HTML5Demos.Dialogs.OpenFromDocumentStorageEventArgs();
args.documentFile = file;
args.loadEmbeddedAnnotations = false;
args.annotationsFile = null;
})


After I get the file into OpenFromDocumentStorageEventArgs, is it possible for to savetocache immediately?
Without the following commands?

_this.documentViewer.setDocument(document);
_documentId = document.documentId;

_this.documentViewer.prepareToSave();
var doc = _this.documentViewer.document;

lt.Document.DocumentFactory.saveToCache(doc)
.done(function () {
console.log('Document saved to cache with DocumentID: ' + _documentId);
})
.fail(function (jqXHR, statusText, errorThrown) {
alert("Document Viewer Error - See console for details.");
});

Hello,

Unfortunately I believe you would have to upload the file, then save that to the cache (though the upload process will theoretically be uploading to the cache already). If you refer to Main.File.ts in our App1 project, you'll find the openFromDocumentStorageMenuItem_Click method (line 188 in the TypeScript file). It shows the data being handled using the following logic:


Once you have the document either by loadFromUri or uploadFile, you can simply call DocumentFactory.saveToCache on that document:

Note: None of the commands above require the DocumentViewer, as requested, only the DocumentFactory:
