How to set checkbox values in PDF Viewer

[Saurabh D]

Hi,

I'm using the pdfviewer.importformfields method on the pdf viewer control for a form-filling mechanism. This works for text-based fields - I give it a JSON that has the field values for every field ID, and the importformfields method sets the values in the respective fields. However, I would like to set some of the checkbox values using this method, but it does not seem to working. The checkboxes don't seem to have a true/false values but rather seem to have a bunch of different values, which I'm not able to understand. Please see screenshot attached for some of the values I was able to infer on checkbox fields using the exportformfields method.

Basically, I'm trying to set the value of some checkbox fields using ImportFormFields but it is not working. Would be great if you can assist.

Thanks.

Hi,

After looking into this further, it looks like the JSON supplied to the ImportFormFields method needs to substitute special characters with their hexadecimal representation. For e.g. I can see that the date 01/01/2020 is stored as 01_x0031_01_x0031_2020 (where the slash "/" is replaced by _x0031_). This approach clearly has downsides, since I will have to find/replace all special characters with their hex equivalents. Is there an easier approach to this?

Thanks.

Hi Saurabh ,  

Please find the details of your query from the below, 

Query	Response
Can we able to change the check box exported status ON/OFF to true/false.	We have checked the possibilities to changing the check box status in Json export, but the ON/OFF is preserved in the PDF document itself. We can export the current form data into JSON file format. So that we could not change the check box export status to True/False.
Can we able to remove the Unicode character on the exported data.	For removing the Unicode character on exported data, it will affect the XML document. Because XML document will not support the whitespace character, so that we encode form fields name into Unicode characters while exporting to JSON data.

Hi,

Thanks for responding. Understood about the encoding - I wrote a function to find/replace any non-alphanumeric characters with their hex equivalents. It works so okay on that front.

Regarding the checkboxes, it's not a question of changing from On/Off. What I'm seeing is that the JSON contains different values for checkboxes (not just on/off). For e.g., I'm attaching a sample application that I'm working with. You can follow these steps:

a. Run the application

b. Once the form loads, check some of the checkboxes - I have attached screenshots showing which ones I tested with.

c. Click the [Save] button - this will call exportJSON and export the fields to JSON file in AppData folder.

If you check the values that are being set for these checkboxes, some have value of "M" and others have value of "_x0023_20FLR_x0023_20".

What I'm trying to do is to basically create a JSON file with the field values from the database and fill the form using importFormFields. It works for text fields but is being thrown off because of the variations in checkbox values.

Thanks.

Hi Saurabh,

On our further analysis , while exporting  form fields we have added the details like field name and field value. We have adding the check box values ,if it is checked we added the checked value like (Male-M or Female-F) or else we have add the value is “OFF” and it is our default behaviour. So only we can able to import this data. 

We have get the values from field dictionary “V” and “AS” entry. The dictionary itself the value is “M”,  and also we get the value of "#20FLR#20" for the form field Part1 Unit[0]checkbox. 

Please refer the below screen shot for more reference.

Hi Selvakumar,

Thanks for the reply - I'm still not clear on what the solution is here. Are you saying that it is not possible to set the value of checkbox fields during the importformfields method?

[Akshaya Arivoli]

Hi Saurabh, 

As mentioned earlier ,if the checkbox is checked we have added the checked value like (Male-M or Female-F) or else we have add the value is “OFF” based on the value preserved in the from field dictionary in the PDF document structure and it is our default behavior. So, it is not possible to set the check box value while importing the form fields, the check box value will be preserved as in the PDF document itself
