PdfDocumentProcessor.LoadDocument(Stream, Boolean) Method

Opens a PDF document from the specified stream using detach stream mode.

Namespace: DevExpress.Pdf

Assembly: DevExpress.Docs.v24.1.dll


public void LoadDocument(
    Stream stream,
    bool detachStreamAfterLoadComplete


Name Type Description
stream Stream

A Stream object.

detachStreamAfterLoadComplete Boolean

true the PDF Document API component completes all input operations after loading a document; false the stream should not be closed or modified until the PDF Document API component finishes using a document.


The PDF Document API component expects that the input stream will not be modified or closed before the component finishes using a document. Pass true as the detachStreamAfterLoadComplete method parameter to force the PDF Document API component to complete all input operations after loading a document.

If the PdfProcessor fails to load the document, an ArgumentException is thrown.

The code sample below uses PdfFormData to set form field values:

// Load a document with an interactive form.
using (PdfDocumentProcessor documentProcessor = new PdfDocumentProcessor()) {
    documentProcessor.LoadDocument(filePath + fileName + ".pdf");

    // Obtain interactive form data from a document.
    PdfFormData formData = documentProcessor.GetFormData();

    // Specify the value for FirstName and LastName text boxes.
    formData["FirstName"].Value = "Janet";
    formData["LastName"].Value = "Leverling";

    // Specify the value for the Gender radio group.
    formData["Gender"].Value = "Female";

    // Specify the check box checked appearance name.
    formData["Check"].Value = "Yes";

    // Specify values for the Category list box.
    formData["Category"].Value = new string[] { "Entertainment", "Meals", "Morale" };

    // Obtain data from the Address form field and specify values for Address child form fields.
    PdfFormData address = formData["Address"];

    // Specify the value for the Country combo box. 
    address["Country"].Value = "United States";

    // Specify the value for City and Address text boxes. 
    address["City"].Value = "California";
    address["Address"].Value = "20 Maple Avenue";

    // Apply data to the interactive form. 

    // Save the modified document.
    documentProcessor.SaveDocument(filePath + fileName + "_new.pdf");
