Remarks

Call the LoadDocumentTemplate procedure to import a document from a file in any supported format. Imported content replaces the current document.

The TdxRichEditControl component treats the imported document as a template (restores default values for Options.DocumentSaveOptions.CurrentFileName and Options.DocumentSaveOptions.CurrentFormat properties). A successful document import operation raises the OnDocumentLoaded event.

The OnDocumentClosing event occurs immediately before a document import operation if the current document contains unsaved changes.

Source Document Format Detection

The LoadDocumentTemplate uses the specified file name extension to identify the source document format. If the file name has no extension, LoadDocumentTemplate iterates through all supported formats to find the best possible match for the source document.

Import Format Support

Support for all document formats, except for TXT and RTF, is initially disabled for the TdxRichEditControl component to avoid excessive dependencies. To enable support for available formats, add all required dependencies at design time or in code:

ExtensionDocument FormatFormat ValueImport/Export SettingsSupport / Required Dependencies

RTF/rtfRich Text FormatRtfOptions.Import.Rtf/Options.Export.RtfBuilt-in Support

At design time, you can right-click the TdxRichEditControl component, expand the Add Unit to Support menu item, and add all required dependencies.

End-User Load Command

The TdxRichEditControl component ships with the TdxRichEditControlLoadDocument class you can use to add a Load end-user command in your application.

Tip

You can use automatic UI generation to create a Ribbon or toolbar UI populated with all predefined end-user commands available for TdxRichEditControl as demonstrated in the following topic:

How to Create a Ribbon or Toolbar UI for your Rich Edit-based Application
