How to read Form fields (ActiveX contol) values from word 2010 using OpenxmlSDK

[Eric White]

Hi Prasad,

I’m not sure how the ActiveX controls store the data, but an easy way to find out is to use the Open-Xml-Sdk productivity tool to compare before/after versions of the document after you change values.

Hello Eric
Thanks for the reply.
Sure. The easiest way to find out is to compare before and after version of document using Productivity tool.
Actually following code will work to fetch values of ActiveX control but for word 2007 only

using System;
using System.Collections.Generic;
using System.Xml.Linq;
using System.Xml;
using System.IO;
using System.Text;
using DocumentFormat.OpenXml;
using DocumentFormat.OpenXml.Wordprocessing;
using DocumentFormat.OpenXml.Packaging;

namespace OpenXMLTest
{
    class Program
    {
        const string textBoxId = "{8BD21D10-EC42-11CE-9E0D-00AA006002F3}";<
span class="pln" style="margin: 0px; padding: 0px; border: 0px; font-size: 13px; color: rgb(48, 51, 54);">
        const string radioButtonId = "{8BD21D50-EC42-11CE-9E0D-00AA006002F3}";
        const string checkBoxId = "{8BD21D40-EC42-11CE-9E0D-00AA006002F3}";

        static void Main(string[] args)
        {
            string fileName = @"C:\Users\Andy\Desktop\test_l1demo.docx";
            using (WordprocessingDocument doc = WordprocessingDocument.Open(fileName, false))
            {
                foreach (Control control in doc.MainDocumentPart.Document.Body.Descendants())
                {
                    Console.WriteLine();
                    Console.WriteLine("Control {0}:", control.Name);
                    Console.WriteLine("Id: {0}", control.Id);

                    displayControlDetails(doc, control.Id);
                }
            }

            Console.Read();
        }

        private static void displayControlDetails(WordprocessingDocument<
span class="pln" style="margin: 0px; padding: 0px; border: 0px; font-size: 13px; color: rgb(48, 51, 54);"> doc, StringValue controlId)
        {
            string classId, type, value;

            OpenXmlPart part = doc.MainDocumentPart.GetPartById(controlId);
            OpenXmlReader reader = OpenXmlReader.Create(part.GetStream());
            reader.Read();
            OpenXmlElement controlDetails = reader.LoadCurrentElement();

            classId = controlDetails.GetAttribute("classid", controlDetails
.NamespaceUri).Value;

            switch (classId)
            {
                case textBoxId:
                    type = "TextBox";
                    break;
                case radioButtonId:
                    type = "Radio Button";
                    break;
                case checkBoxId:
                    type = "CheckBox";
                    break;
                default:
                    type = "Not known";
                    break;
            }

            value = "No value attribute"; //displays this if there is no "value" attribute found
            foreach (OpenXmlElement child in controlDetails.Elements())
            {
                if (child.GetAttribute("name", controlDetails.NamespaceUri).Value == "Value")
                {
                    //we've found the value typed by the user in this control
                    value = child.GetAttribute("value", controlDetails.NamespaceUri).Value;
                }
            }

            reader.Close();

            Console.WriteLine("Class id: {0}", classId);
            Console.WriteLine("Control type: {0}", type);
            Console.WriteLine("Control value: {0}", value);

        }
    }
}

I observed, the way word 2007 store ActiveX values are different than word 1010, I think tags are changed.
and the code is somehow not working for word 2010 and above

Thanks
Prasad
