PdfIntegrationProvider.OnDocumentDownloading Method

Called before a document is downloaded.

Namespace: RadPdf.Integration
Assembly: RadPdf (in RadPdf.dll) Version: 4.2.0.0 (4.2.0.0)

Syntax

public virtual void OnDocumentDownloading(
	DocumentDownloadingEventArgs e
)

Public Overridable Sub OnDocumentDownloading ( 
	e As DocumentDownloadingEventArgs
)

Parameters

e: Type: RadPdf.Integration.DocumentDownloadingEventArgs
An object (defined by DocumentDownloadingEventArgs) that contains event data.

Remarks

Inheriting classes can override this method to perform other tasks, modify aspects of downloading the document, or cancel the download all together. If this method is overridden in an inheriting class, you must call the base implementation.

Examples

The following example overrides the default PdfIntegrationProvider to create a custom Integration Provider for the web application. This custom Integration Provider flattens forms before they are downloaded for all PdfWebControl instances.

Copy

using System;
using System.Web;

using RadPdf.Integration;

public class CustomPdfIntegrationProvider : PdfIntegrationProvider
{
    public override void OnDocumentDownloading(DocumentDownloadingEventArgs e)
    {
        base.OnDocumentDownloading(e);

        e.FlattenDownload = true;
    }
}

The following web.config file registers the above custom Integration Provider. This example assumes that CustomPdfIntegrationProvider is in the directory App_Code of your ASP.NET web application.
