In the TX Text Control ActiveX, there was a parameter (*CurSelection*) in the *Load* method which specifies, whether the loaded document replaces the content or whether it should be appended. In TX Text Control .NET for Windows Forms, there is no such parameter, but a new class: the **Selection** class. This class can be used to manipulate the currently selected text. Additionally, this class contains a *Load* and *Save* method to load documents into a selection or to save only the selected text: ``` TextControl1.Selection.Load(path, StreamType) ``` --- ## 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.
