I am using the following code to open a ParForm.pdf, set field values and then return the updated pdf as test.pdf. I am able to successfully set the values in the Text fields (“Date”, “Date Received”, “From”, “Position Location”) but I am unable to set the values for 3 RadioButtons grouped with a common name of “Group1”. Please let me know how to set the grouped radio button values. Thanks.
public FileResult HandleFormDataSubmit()
{
var fields = new Dictionary<string, StringValues>
{
{ "Date", "02/03/2020" },
{ "Date Received", "02/04/2020" },
{ "Group1", new StringValues(new string[] { "Off", "Off", "On" }) },
{ "From", "First Last" },
{ "Position Location", "MyCity" }
};
var values = fields.ToList();
var fieldValues = values.Select(kvp_ => new KeyValuePair<string, IList<string>>(kvp_.Key, kvp_.Value.ToArray())).ToArray();
var ms = ImportFormData(fieldValues);
var result = new FileStreamResult(ms, "application/pdf")
{
FileDownloadName = "Test.pdf"
};
return result;
}
public static Stream ImportFormData(KeyValuePair<string, IList<string>>[] fieldValues)
{
GcPdfDocument pdf = new GcPdfDocument();
var pdfFile = Path.Combine("Resources", "PDFs", "ParForm.pdf");
using var fs = new FileStream(pdfFile, FileMode.Open, FileAccess.Read);
pdf.Load(fs);
pdf.ImportFormDataFromCollection(fieldValues);
var outMs = new MemoryStream();
pdf.Save(outMs);
outMs.Seek(0, SeekOrigin.Begin);
return outMs;
}
