Bug Report
PdfProcessing: ArgumentNullException is thrown when exporting a document that contains a Widget created with FixedContentEditor
When exporting a document that contains a Widget created with FixedContentEditor an exception is thrown: System.ArgumentNullException: 'Value cannot be null. Parameter name: context'
It can be reproduced using the following code snippet:
RadFixedDocument document = new RadFixedDocument();
var page = document.Pages.AddPage();
FixedContentEditor editor = new FixedContentEditor(page);
PushButtonField pushButton = new PushButtonField("button");
editor.Position.Translate(20, 450);
editor.DrawWidget(pushButton, new Size(100, 20));
string path = "Exported.pdf";
File.Delete(path);
using (Stream output = File.OpenWrite(path))
{
PdfFormatProvider provider = new PdfFormatProvider();
provider.Export(document, output);
}Workaround: Add the form filed to the AcroForm`s FromFields collection before exporting the document:
document.AcroForm.FormFields.Add(pushButton);
