RichEditControl.LoadDocument(String) Method
Loads a document from the specified file. The file format is determined by its content.
Namespace: DevExpress.Xpf.RichEdit
Assembly: DevExpress.Xpf.RichEdit.v20.2.dll
NuGet Packages: DevExpress.WindowsDesktop.Wpf.RichEdit, DevExpress.Wpf.RichEdit
Declaration
Parameters
| Name | Type | Description |
|---|---|---|
| fileName | String | A string specifying the file to load (including the full path). |
Returns
| Type | Description |
|---|---|
| Boolean | true, if the document is successfully loaded; otherwise, false. |
Remarks
The format of the document loaded from a stream is detected automatically by the built-in IFormatDetectorService service implementation. The following formats are detected:
- DOC, DOCX, RTF, HTM, HTML, MHT, XML, EPUB;
- ODT - non-encrypted files only.
Plain text cannot be detected automatically. To load a plain text document, use another method override with the document format DocumentFormat.PlainText as a parameter.
If the format detection fails or the passed string is null, the RichEditControl.InvalidFormatException event fires.
After loading a document, the DXRichEditDocumentSaveOptions.CurrentFileName property is set to the file name and the DXRichEditDocumentSaveOptions.CurrentFormat property is set to the detected format.
Determine a moment when the document model can be safely modified using the RichEditControl.DocumentLoaded event. Call the LoadDocument method in the Form.Loaded event handler to work with the DocumentLoaded event. Handle the DocumentLayout.DocumentFormatted event to check the loaded document’s layout.
Tip
Use LoadDocument method overloads which explicit format definition to improve performance.
