Content Control (drop down) Value is Changed after re-saving DOCX using .NET

We have a document that contains a Word IF field that includes content controls bound to XML data. This is included in the document using an AltChunk.

Calling document.UpdateFields() does not make the field update. However opening the document in Word and updating the field makes it update as expected.

Debugging the code reveals that the field is included in the document range, but the bound data is not present. The bound data in the content controls is shown correctly when opening the document, it just appears that it is not being used when calculating the field.

We are using Aspose.Words v21.3.0. I have an example document showing the behavior if required.


Could you please ZIP and attach your input, problematic and expected output documents here for testing? We will investigate the issue and provide you information on it.

We have tested the scenario using the input document (IF Logic Salutation.docx) and have not found the shared issue. Please check the attached output documents. (46.5 KB)

Please note that Aspose.Words mimics the behavior of MS Word. If you perform the same scenario using MS Word, you will get the same output.


Thank you for your reply. The input document (IF Logic Salutation.docx) you mentioned does indeed work as I expected. However, when you include that document in another document using an AltChunk, it is then I face the issue. See Testing IF Statements in AltChunk.docx in the previous
