In TX Text Control X19, the DocumentServer will be extended with a new namespace: TXTextControl.DocumentServer.PDF. This namespace is the new home for PDF specific tasks that doesn't require a connected Text Control.

Extracting Forms Data

Import FormField Objects

The following code shows how to get all AcroForm fields from a physical PDF document using the GetAcroFormFields method that accepts file names and byte arrays:

FormField[] acroForms = 
    TXTextControl.DocumentServer.PDF.Forms.GetAcroFormFields("form.pdf");

foreach (FormField field in acroForms)
{ 
    switch (field)
    {
        case TXTextControl.DocumentServer.PDF.AcroForms.FormTextField textField:
            Console.WriteLine(textField.Value);
            break;

        case TXTextControl.DocumentServer.PDF.AcroForms.FormCheckBox checkBoxField:
            Console.WriteLine(checkBoxField.IsChecked);
            break;

        case TXTextControl.DocumentServer.PDF.AcroForms.FormComboBox comboBoxField:
            foreach(var item in comboBoxField.Options)
                Console.WriteLine(item);
            break;
    }
}

The return value is an array of FormField objects that contains all fields of the document:

The above code shows how to loop through this array and to cast those types in a switch/case statement to get the proper values from those fields.

This new feature allows you to support the complete PDF forms workflow where TX Text Control can be used to:

• Create PDF fillable form documents.
• Share those documents.
• Collect and analyze completed forms.
