Dynamically Change Barcode(Data Code)

[farhath]

I need to know if it is possible to change the Barcode ->Data ->Code at run time. I tried this code:
IWCGJQBarCode2.DataCodaBar.Code:='12234';
The Error I am getting: Invalid Class Type Cast

IWCGJQBarCode2 is displaying correctly but I need to change its code at run time, any help?

Hi,

Hi,

So you need assign proper property/settigns:

delphi code

IWCGJQBarCode1.DataCode128.Code:= '1234';

And after the setting, you will need to use the AjaxReRender method:

delphi code

IWCGJQBarCode1.AjaxReRender(True,False);

Best Regards.

Hi assapan,

is there a way to download image of barcode ?

Yes, you must use the IWCGJQHTML2Canvas component for that.

Example:

Code: Select all

IWCGJQHTML2Canvas1.ConvertAndSaveAsPNG(IWCGJQBarCode1, 'C:\tmp\test.png');

Best Regards.
