InsertTextInput and Empty characters

Hi all,
I’m using documentBuilder to insert a text box:

documentBuilder.InsertTextInput(bookmark, TextFormFieldType.RegularText, string.Empty, string.Empty, 100);

but if the document is saved and opened in Word, then the text box does not contain any marks or characters => is not visible for the user.
If is filled and emptied, then the formField is displayed as usually in Word - is it neccesery to setup something? The only advice I found is to use e.g. " " as the 4th parameter but it is not exactly what we need.
Thanks very much, we are using Aspose.Words ver. 6.2.0.0

Hi

Thanks for your request. When you insert text input formfields, MS Word insert five special characters (\x2002) as a default value. So you can do the same. Please see the following code:

private void InsertTextInput(DocumentBuilder builder, string name, string value)
{
    builder.InsertTextInput(name, TextFormFieldType.RegularText, string.Empty,
        string.IsNullOrEmpty(value) ? "\x2002\x2002\x2002\x2002\x2002" : value, 100);
}

Hope this helps.
Best regards,
