A text part can either be the document's main text, a text frame, a footnote section or a header or footer. A text frame is represented through a TextFrame object, a header or footer through a HeaderFooter object, a footnote section through a FootnoteSection object and the document's main text is represented through a MainText object. A TextPartCollection object contains all these objects in a geometric order. The first object in the collection is the main text, followed by all text frames in geometric order. At the end of the collection all headers and footers are contained also geometrically ordered. All objects in a text part collection implement the IFormattedText interface. The collection can be obtained with the TextControl.TextParts, WPF.TextControl.TextParts or ServerTextControl.TextParts property. The TextPartCollection class implements the IEnumerable and the ICollection interfaces. - [TrackedChange Class](https://docs.textcontrol.com/tx-text-control-dotnet-wpf/reference/txtextcontrol/trackedchange/llms.txt): A TrackedChange object represents a change made to the document after anyone has revised the document. After tracking changes has been turned on with the IsTrackChangesEnabled property, a TextControl marks up new changes made to the document. Every change is represented through a TrackedChange object, all of these objects are contained in the TrackedChangeCollection which can be obtained with the TrackedChanges property. - [TrackedChangeCollection Class](https://docs.textcontrol.com/tx-text-control-dotnet-wpf/reference/txtextcontrol/trackedchangecollection/llms.txt): Contains all tracked changes in the main text or another part of a document. It is a collection of objects of the type TrackedChange. A collection object can be obtained with the TextControl.TrackedChanges, the HeaderFooter.TrackedChanges or the TextFrame.TrackedChanges property. The TrackedChangeCollection class implements the IEnumerable and the ICollection interfaces. A TrackedChange object represents a change of the document after someone has reworked the document. After tracking changes has been turned on with the IsTrackChangesEnabled property, a TextControl marks up new changes made to the document. - [TrackedChangeEventArgs Class](https://docs.textcontrol.com/tx-text-control-dotnet-wpf/reference/txtextcontrol/trackedchangeeventargs/llms.txt): The TrackedChangeEventArgs class provides data for the TrackedChangeChanged, TrackedChangeCreated, TrackedChangeStateChanged, and TrackedChangeDeleted events. When a tracked change is deleted, the TrackedChange object provided with the event data has the following valid properties: ChangeKind, UserName, HighlightColor, HighlightMode and ChangeTime. All other properties are undefined. - [UserDefinedPropertyDictionary Class](https://docs.textcontrol.com/tx-text-control-dotnet-wpf/reference/txtextcontrol/userdefinedpropertydictionary/llms.txt): An instance of the UserDefinedPropertyDictionary class contains all user-defined document properties contained in a loaded document or which will be saved in a document. The UserDefinedPropertyDictionary class is used with the LoadSettings.UserDefinedDocumentProperties and SaveSettings.UserDefinedDocumentProperties properties. Each entry in the dictionary is a key/value pair, where the key is the name of the document property and the value is the document property's value. The foreach statement of the C# language (for each in Visual Basic) returns an object of the type of the elements in the collection. Since each element is a key/value pair, the element type is System.Collections.DictionaryEntry. The name must be of the type System.String and is limited to 255 characters. The value can be of the type System.String, System.Boolean, System.Int32 or System.Double. - [VersionInfo Class](https://docs.textcontrol.com/tx-text-control-dotnet-wpf/reference/txtextcontrol/versioninfo/llms.txt): The VersionInfo class provides information about the running TX Text Control version, such as the version number, the installed service pack number and the product level. - [WPF.MiniToolbar Class](https://docs.textcontrol.com/tx-text-control-dotnet-wpf/reference/txtextcontrol/wpf-minitoolbar/llms.txt): The WPF.MiniToolbar class is the base class of the built-in mini-toolbars of a WPF.TextControl. A mini-toolbar is a contextual toolbar showing elements to format the document depending on the current context. It is inherited from the System.Windows.Controls.Primitives.Popup class. The following describes only the properties, methods and events defined through the WPF.MiniToolbar class. For a list of properties, methods and events inherited from the System.Windows.Controls.Primitives.Popup class see the .NET Framework reference. - [WPF.MiniToolbarOpeningEventArgs Class](https://docs.textcontrol.com/tx-text-control-dotnet-wpf/reference/txtextcontrol/wpf-minitoolbaropeningeventargs/llms.txt): The WPF.MiniToolbarOpeningEventArgs class provides data for the WPF.TextControl.MiniToolbarOpening event of a WPF.TextControl. This event occurs to handle displaying context sensitive mini toolbars. The MiniToolbarContext property informs for which context the mini-tooolbar will be opened. Depending on that context the pre-defined mini toolbar WPF.TextMiniToolbar or WPF.ObjectMiniToolbar are provided by the MiniToolbar property. - [XmlElement Class](https://docs.textcontrol.com/tx-text-control-dotnet-wpf/reference/txtextcontrol/xmlelement/llms.txt): An instance of this class represents an element in a XML document. To iterate through all occurrences of an XML element in a Text Control document the XmlElementCollection class can be used. - [XmlElementCollection Class](https://docs.textcontrol.com/tx-text-control-dotnet-wpf/reference/txtextcontrol/xmlelementcollection/llms.txt): An instance of this class contains all elements of an XML document that have the same element name. It can be obtained with the TextControl.GetXmlElements method. - [XmlErrorEventArgs Class](https://docs.textcontrol.com/tx-text-control-dotnet-wpf/reference/txtextcontrol/xmlerroreventargs/llms.txt): The XmlErrorEventArgs class provides data for the TextControl.XmlNotWellFormed and TextControl.XmlInvalid events. - [zoomoption](https://docs.textcontrol.com/tx-text-control-dotnet-wpf/reference/txtextcontrol/zoomoption/llms.txt) - [zorder](https://docs.textcontrol.com/tx-text-control-dotnet-wpf/reference/txtextcontrol/zorder/llms.txt) --- ## Nearby - **Previous:** [.NET API](https://docs.textcontrol.com/tx-text-control-dotnet-wpf/reference/dotnet-api/llms.txt) - **Next:** [TXTextControl Enumerations](https://docs.textcontrol.com/tx-text-control-dotnet-wpf/reference/txtextcontrol/enumerations/llms.txt)
