RichEditControl.LoadDocument(String, DocumentFormat, String) Method

Loads a document from the file in the specified format. External content for HTML format is retrieved using the specified source (base) URI.

Namespace: DevExpress.Xpf.RichEdit

Assembly: DevExpress.Xpf.RichEdit.v20.2.dll

Declaration

public virtual bool LoadDocument(
    string fileName,
    DocumentFormat documentFormat,
    string sourceUri
)
Public Overridable Function LoadDocument(
    fileName As String,
    documentFormat As DocumentFormat,
    sourceUri As String
) As Boolean

Parameters

Name Type Description
fileName String

A string specifying the file to load (including the full path).

documentFormat DocumentFormat

One of the DocumentFormat enumeration members, indicating the document format.

sourceUri String

A string representing the document URI.

Returns

Type Description
Boolean

true, if the document is successfully loaded; otherwise, false.

Remarks

If the document is in a different format than specified or the passed string is null, the RichEditControl.InvalidFormatException event fires.

The LoadDocument method can be used to load HTML files with external references. To load a file filename.html obtained by saving a document in HTML format from Rich Edit, set the sourceUri to filename_files:

bool result = richEdit.LoadDocument("test.htm", DocumentFormat.Html, "test_files");
TIP

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.
