RichEditControl.LoadDocument(String, DocumentFormat, String) Method

SECURITY-RELATED CONSIDERATIONS

Using file paths sourced from untrusted input may expose unauthorized files or allow unintended file access. Always validate and normalize all external paths to prevent path manipulation.

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

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:

C#
VB.NET

csharp

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

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. 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.
