Hi,
In Grid Application, I added a new qrcode field. As I can see there is no value in this “qrcode” field.
So on event “onApplicationInit” I insert the following code.
{qrcode} = "1234";
But when I run the Application, the qrcode field is empty.
May I know what have I done wrong? Is it the way I assign value to “qrcode” field is wrong?
Please advice, thank you.
Use onload event and a valid value for the barcode. Did you apply a custom field or is it a field from the database?
Hi,
It’s a custom field (not from DB) and QR Code can be any text so there is no Valid Value.
I’m trying to show the “name” of the row as QR Code. So I make a new virtual field and hope to assign it’s value as the same as the “name” field value.
Please advice, thank you.
I tried to change a field with value in the DB as QR Code field, the QR code can be display correctly. Just don’t know how to use it using virtual field.
And its a Grid Application where I don’t see the onLoad event available.
Please advice, thank you.
though not so clear about the problem, i wanna try my best to offer the related resources about qr code ,i 've used some platforms like asp.net to create qr code barcode,maybe you can have a look if you have some free time,hope you can find sth,helpful! Good luck!

hey, i’m wondering this ,any progress?
also interested!
Indeed and… why only available in a grid application and not in a form or control?
Thanks for the reference, I need a resource for java qr code generation, so lucky java resources are also available here.
