These properties remain with a document and can be viewed by all MS Word users that open the document. Several property management servers provide data tracking capabilities to search for, sort, and track documents based on document properties. Using TX Text Control X14 (Windows Forms, WPF and ASP.NET), custom properties can be set and retrieved using the *SaveSettings* and *LoadSettings* parameter in the [Load](https://docs.textcontrol.com/textcontrol/windows-forms/ref.txtextcontrol.textcontrol.load.method.htm) and [Save](https://docs.textcontrol.com/textcontrol/windows-forms/ref.txtextcontrol.textcontrol.save.method.htm) methods. The new class *UserDefinedPropertyDictionary* contains all custom properties stored in a document. Supported value types are: - System.String - System.Boolean - System.Int32 - System.Double The following sample code shows how to add new custom properties to a document: ``` TXTextControl.UserDefinedPropertyDictionary userSettings = new TXTextControl.UserDefinedPropertyDictionary(); userSettings.Add("CustomPropertyString", "Custom property string"); userSettings.Add("CustomPropertyInt32", 123); userSettings.Add("CustomPropertyBoolTrue", true); userSettings.Add("CustomPropertyBoolFalse", false); userSettings.Add("CustomPropertyDouble", 123.232); TXTextControl.SaveSettings saveSettings = new TXTextControl.SaveSettings() { UserDefinedDocumentProperties = userSettings }; textControl1.Save("test.rtf", TXTextControl.StreamType.RichTextFormat, saveSettings); ``` Unlimited number of custom properties can be stored in the document formats MS Word (DOC), Office Open XML (DOCX), Rich Text Format (RTF) and the internal TX Text Control format (TX). The following code snippet shows how to load and retrieve the custom properties stored in a document: ``` TXTextControl.LoadSettings loadSettings = new TXTextControl.LoadSettings(); textControl1.Load("test.rtf", TXTextControl.StreamType.RichTextFormat, loadSettings); foreach (DictionaryEntry property in loadSettings.UserDefinedDocumentProperties) { Console.WriteLine(property.Key + ": " + property.Value.ToString()); } ``` Stay tuned for more information about the upcoming release X14! --- ## About Bjoern Meyer As CEO, Bjoern is the visionary behind our strategic direction and business development, bridging the gap between our customers and engineering teams.
