RichEditDocumentServerExtensions.SaveDocumentAsync(RichEditDocumentServer, String, DocumentFormat, EncryptionSettings) Method

Asynchronously saves the document to a file with the specified document format and encryption options.

Namespace: DevExpress.XtraRichEdit

Assembly: DevExpress.Docs.v20.2.dll

Declaration

public static Task SaveDocumentAsync(
    this RichEditDocumentServer self,
    string fileName,
    DocumentFormat documentFormat,
    EncryptionSettings encryptionSettings
)

Parameters

Name Type Description
self RichEditDocumentServer

The current RichEditDocumentServer instance.

The path to the file to which to save the document.

documentFormat DocumentFormat

The enumeration value that indicates the document format.

Type Description
Task

An asynchronous export operation.

Remarks

IMPORTANT

The RichEditDocumentServerExtensions class is defined in the DevExpress.Docs.v20.2.dll assembly. Add this assembly to your project to use the RichEditDocumentServerExtensions members. You need an active license for the DevExpress Office File API Subscription or DevExpress Universal Subscription to use this library in production code.

The SaveDocumentAsync method call does not automatically change the RichEditDocumentServer.Modified property value.

Handle the RichEditDocumentServer.BeforeExport event if the specified document format requires that a certain type of content should be saved as external objects. Use the HtmlDocumentExporterOptions.EmbedImages property to specify whether images are embedded in HTML code or a custom IUriProvider is used to construct src image references.

IMPORTANT

Take into account the following when you call this method:

  • The events fired by this method's call may occur in a different thread than the target operation.

  • The operation is not thread safe (documents should not be accessed simultaneously by different threads). Wait until the operation is completed before working with the document, i.e., use the await operator.

The code sample below merges two asynchronously loaded documents, and encrypts and exports the result:

private async void MergeDocuments()
{
  using (RichEditDocumentServer wordProcessor = new RichEditDocumentServer())
  using (RichEditDocumentServer wordProcessor2 = new RichEditDocumentServer())
  {
      await Task.WhenAll(new Task[]
      {
    wordProcessor.LoadDocumentAsync("Document1.docx"),
    wordProcessor2.LoadDocumentAsync("Document2.docx")
      });
      wordProcessor.Document.AppendDocumentContent(wordProcessor2.Document.Range);

      EncryptionSettings encryptionSettings = new EncryptionSettings("12345", EncryptionType.Strong);

      await wordProcessor.SaveDocumentAsync("merged.docx", DocumentFormat.OpenXml, encryptionSettings);
  }
}
