Thank you for contacting Syncfusion support.
We have checked the provided document and code snippet. The check box field items in the provided document does not have any different dictionary properties in file level. So, we could not differentiate with properties. However, we have analyzed further in the document structure level, the check box item in the 0th (zero) index is No and the item in 1st index on the collect is Yes. Based on the index on the PdfLoadedCheckBoxItemCollection, you can determine which one is checked.
Please find the screenshot of the check box items under the name “check 2”, it does not have any difference in dictionary properties.
Please let me know if you need any further assistance on this.
