Here are the modules I have injected, as well as how I load the form:
@{ string serviceUrl = VirtualPathUtility.ToAbsolute("~/PDFApiViewer/");}
@(Html.EJS().PdfViewer("pdfviewer")
.ToolbarSettings(new Syncfusion.EJ2.PdfViewer.PdfViewerToolbarSettings
{
ShowTooltip = false,
ToolbarItems = "PageNavigationTool, PrintOption, " +
"SelectionTool, SearchOption, MagnificationTool, UndoRedoTool"
})
.EnableCommentPanel(false)
.FormFieldFocusOut("formfieldModified")
.FormFieldClick("formFieldClicked")
.EnableNavigationToolbar(false)
.EnableAnnotationToolbar(false)
.DocumentLoad("docLoad")
.EnableFormDesigner(false)
.EnableAutoComplete(false)
.Render())
var pdfViewer = document.getElementById('pdfviewer').ej2_instances[0];
pdfViewer.textFieldSettings = {
borderColor: "rgb(0, 0, 0)",
backgroundColor: "rgba(0, 20, 200, 0.2)"
}
pdfViewer.serviceUrl = '@serviceUrl';
pdfViewer.documentPath = '@(Model.FileInformation.Sections[0].Name)_0';
pdfViewer.ajaxRequestInitiate = ajaxRequestInitiate;
pdfViewer.dataBind();
pdfViewer.load(pdfViewer.documentPath, null);
To change the category from "Number" to "None", we are using the Adobe PDF Editor.
The form fields do appear when I load the PDF in the PDF viewer. The issue stems from when I set the data in the back end. I load the form, find the field type, then set the value. Here is the function that takes the field name, the value that is to be set and adds it to the PDF:
/// Set the form field data for the specified field.
public string SetFieldData(string fieldname, string value)
{
var actpdf = pages.FirstOrDefault(p => p.PageIndex == activePage);
var file = actpdf.Pages[actpdf.Pages.Count - 1];
using (var fs = new FileStream(file, FileMode.Open))
{
var pdf = new PdfLoadedDocument(fs);
var pdfForm = pdf.Form;
pdfForm.SetDefaultAppearance(false);
PdfLoadedField theField = null;
for (int i = 0; i < pdfForm.Fields.Count; i++)
{
if (pdfForm.Fields[i].Name.Split('#')[0].ToLower().Equals(fieldname.ToLower()))
{
theField = (PdfLoadedField)pdfForm.Fields[i];
}
}
if (theField != null)
{
// theField = (PdfLoadedField)pdfForm.Fields[actpdf.Fields[actfield.Key]];
//theField = (PdfLoadedField)pdfForm.Fields[actpdf.Fields[fieldname.ToLower()]];
// See if the fields is atext box.
if (theField.GetType() == typeof(PdfLoadedTextBoxField))
{
if (theField.Name.Contains("#"))
{
// Format the value based on formatting info
var fieldInfo = theField.Name.Split('#');
var fieldFormat = fieldInfo[1]; // must be N for number right now.
var fieldDecimals = fieldInfo[2]; // number of decimal places
if (fieldFormat.ToLower().Equals("n"))
{
int fieldVal;
value = value.Split('.')[0];
if (Int32.TryParse(value, out fieldVal))
{
((PdfLoadedTextBoxField)theField).Text = fieldVal.ToString("N0");
}
else
{
((PdfLoadedTextBoxField)theField).Text = value;
}
}
else
{
((PdfLoadedTextBoxField)theField).Text = value;
}
}
else
{
((PdfLoadedTextBoxField)theField).Text = value;
}
}
if (theField.GetType() == typeof(PdfLoadedCheckBoxField))
{
((PdfLoadedCheckBoxField)theField).Checked = (value.ToUpper().Equals("Y"));
}
}
var ms = new MemoryStream();
pdf.Save(ms);
ms.Position = 0;
pdf.Close(true);
var newfs = new FileStream(file, FileMode.Open, FileAccess.Write);
var bytes = ms.ToArray();
newfs.Write(bytes, 0, (int)bytes.Length);
ms.Dispose();
newfs.Dispose();
}
return file;
}
I have attached the empty PDF file (titled 025ACORD316 - empty form) and I have attached the PDF that gets filled in the back end before its displayed in the viewer (populated form), and a video where I discuss this in a bit more detail to hopefully alleviate any questions.
Let me know if you need anything else!
