SECURITY NOTE

Suppress Control Requests to Download Data from External URLs

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.XtraRichEdit

Assembly: DevExpress.XtraRichEdit.v24.2.dll

Declaration

C#

public virtual bool LoadDocument(
    string fileName,
    DocumentFormat documentFormat,
    string sourceUri
)

VB.NET

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 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:

C#

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

VB.NET

Dim result As Boolean = 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. Handle the DocumentLayout.DocumentFormatted event to check the loaded document’s layout.
