Suppress Control Requests to Download Data from External URLs

Loads a document from the specified file. The file format is determined by its content.

Namespace: DevExpress.XtraRichEdit

Assembly: DevExpress.XtraRichEdit.v24.2.dll

Declaration

C#

public virtual bool LoadDocument(
    string fileName
)

VB.NET

Public Overridable Function LoadDocument(
    fileName As String
) As Boolean

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 value is null, the RichEditControl.InvalidFormatException event fires.

After loading a document, the DocumentSaveOptions.CurrentFileName property is set to the file name and the DocumentSaveOptions.CurrentFormat property is set to the detected format.

Determine a moment when the document model can be safely modified using the RichEditControl.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.
