I am trying to use a qr code, and when I scanned it back it's showing as "message" instead of the actual url which I put in. The following is the codes where I show the qr code. Can someone tell me where I did wrong?



            SfBarcode barcode = new SfBarcode();

            barcode.Symbology = BarcodeSymbolType.QRBarcode;

            QRBarcodeSetting setting = new QRBarcodeSetting();
            setting.InputMode = QRInputMode.BinaryMode;
            setting.XDimension = 8;
            barcode.SymbologySettings = setting;
            barcode.Text = WebHelper.ServerUrl + "signal/" + viewModel.BroadcastSignalViewModel.SignalId;
            barcode.DisplayText = false;

Hi Ken,

Thank you for using Syncfusion Products.


Could you please provide us the string value which is generated from WebHelper.ServerUrl + "signal/" + viewModel.BroadcastSignalViewModel.SignalId, which is given us the input to “barcode.Text”.


So that it will be more helpful for us to investigate in this.

Hi Karthikeyan,

Here is an instance of the url:

I tried to put anything in it like "testing", and all I get back from the bing vision is "message".

Hi Ken,

Thank you for your update.


We have checked with the input text, and it is recognized as URL.

Also it is not an issue with the Barcode control.

Could you please check with the different barcode scanner.


Please let us know if you have any concern.

how do you generate the QR codes, follow the tutorial and steps in encoding barcodes, you will be able to scan codes without error.
