PDF checkbox color not working

[James]

Hi,

I am trying to change the default checkbox tick colour in a downloading PDF file but the tick colour is always black. Any thought please?

Please refer to my code snippet below 

loadedDocument.Form.Fields.TryGetField(field, out PdfLoadedField loadedField);

var sf = loadedField as PdfLoadedCheckBoxField;

sf.ForeColor = new PdfColor(Color.Blue);

sf.BorderColor = new PdfColor(Color.Blue);

sf.BackColor = new PdfColor(Color.Blue);

sf.Checked = true;

Please find the below code snippet to add image in signature field, 

//Load the PDF document 

FileStream docStream = new FileStream("../../../Checkbox1.Pdf", FileMode.Open, FileAccess.Read); 

 

PdfLoadedDocument loadedDocument = new PdfLoadedDocument(docStream); 

 

//Get the loaded form. 

PdfLoadedForm loadedForm = loadedDocument.Form; 

 

loadedForm.SetDefaultAppearance(false); 

//load the check box from field collection 

 

PdfLoadedCheckBoxField loadedCheckBoxField = loadedForm.Fields[0] as PdfLoadedCheckBoxField; 

 

// fill the checkbox forecolor 

loadedCheckBoxField.ForeColor = new PdfColor(Color.Blue); 

 

//load the check box from field collection 

PdfLoadedCheckBoxField loadedCheckBoxField1 = loadedForm.Fields[1] as PdfLoadedCheckBoxField; 

 

// fill the checkbox forecolor. 

loadedCheckBoxField1.ForeColor = new PdfColor(Color.Red); 

loadedCheckBoxField1.Checked = true; 

//Save the document into stream. 

MemoryStream stream = new MemoryStream(); 

loadedDocument.Save(stream); 

stream.Position = 0; 

 

//Close the document. 

loadedDocument.Close(true);
