Default Appearance of PDF Form Fields with same name

Aspose.PDF Product Family

Hello

We are using Aspose.PDF for .NET (22.10.0) to set the appearance of PDF form text boxes.
When there are multiple text boxes with the same name the appearance can be set but when opening the pdf with a viewer only one text box changed appearance.

This is the code I am using to set the fields style:

var doc = new Document(@"c:\temp\form.pdf");

foreach (var widget in doc.Form)
{
    widget.DefaultAppearance = new DefaultAppearance("Courier", 12, System.Drawing.Color.Red);
    var field = widget as Field;
    field.Value = "value";
}

doc.Save(@"c:\temp\out.pdf");

Is there a setting I am missing?

An example input and output form are in attachment.
The text boxes on the left have the same name. The text boxes on the right have different names.

form.pdf (4.3 KB)
out.pdf (6.0 KB)

“When there are multiple text boxes with the same name”

There are actually three TextBoxFields in the document. One of them (named test_0) has two child elements, input rects.

There is no direct access to child elements from the API - for them, changes will be set according to the change in Default Appearance in the main/parent field.

The corresponding changes to the code have been made and will be used starting from library version 23.10

So, specifying Default Appearance (or Value) results in a change for both display areas.
