PdfFieldCollectionRebuildAppearances Property

Gets or sets a value representing whether a RAD PDF should rebuild the appearance streams of all form fields when generating the output PDF.

Namespace:  RadPdf.Data.Document.Objects.FormFields
Assembly:  RadPdf (in RadPdf.dll) Version: 5.8.0.0 (5.8.0.0)
Syntax
Copy
public bool RebuildAppearances { get; set; }

Property Value

Type: Boolean
Remarks
If NeedAppearances and RebuildAppearances are both set to true, the existing appearance streams will be removed, but they will not be rebuilt. A PDF reader will need to construct the form field appearance streams again.
Examples
The following example uses a PdfIntegrationProvider to create a custom Integration Provider which will set RebuildAppearances to true for all documents as they are saved.
C#
Copy
using System;
using System.Web;

using RadPdf.Integration;

public class CustomPdfIntegrationProvider : PdfIntegrationProvider
{
    public override void OnDocumentSaving(DocumentSavingEventArgs e)
    {
        base.OnDocumentSaving(e);

        // Set that RAD PDF should rebuild the appearance streams for
        // form fields in the document.
        e.Document.Fields.RebuildAppearances = 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.
