Slow Assign to property Value

Dear all!!

When we are using aspose.pdf.dll 9.1 or later, at the time to assign any value to property "Value" of a control it is taking too long. when we use previous versions (9.0, 8.9 ..) the assign is faster.

we did the test in two different machines and the results are the same.


string path = upload.PostedFile.FileName;

Document doc = new Document(path);

PdfFileSignature pdf = new PdfFileSignature();

Aspose.Pdf.License licence = new Aspose.Pdf.License();


Aspose.Pdf.InteractiveFeatures.Forms.Field[] _formFields = null;

_formFields = doc.Form.Fields;

TextBoxField txtName = doc.Form["txtNamePru1"] as TextBoxField;

SignatureField signature = doc.Form["SignaturePru"] as SignatureField;

TextBoxField txtRequest = doc.Form["TxtRequestId1"] as TextBoxField;

TextBoxField txtState = doc.Form["TxtState1"] as TextBoxField;

txtName.Value = "Name 1"; // slow assign, about 10 seconds

txtRequest.Value = "REQUEST VALUE ONE "; // slow assign, about 10 seconds

txtState.Value = "STATE VALUE "; // slow assign, about 10 seconds
