I'm generating a pdf report using crystal report, I would like to use Data Map Tool
In c# code I've a dataset containing geographicals fields and some values to display in the map.
public class CrystalReportViewerPlugIn : ICrystalReportViewer
{
private ReportDocument _reportDocument;
private CrystalReportViewer _crystalReportViewer;
public void Init(string fileName, DataSet dataSet)
{
_reportDocument = new ReportDocument();
_reportDocument.Load(fileName);
_reportDocument.SetDataSource(dataSet);
_crystalReportViewer = new CrystalReportViewer();
_crystalReportViewer.DisplayToolbar = false;
_crystalReportViewer.DisplayGroupTree = false;
_crystalReportViewer.PageToTreeRatio = 4;
_crystalReportViewer.RefreshReport();
_crystalReportViewer.ReportSource = _reportDocument;
}
}
Then I export the result into a strem:
public MemoryStream GetCrystalReportResults(string rptFileName, DataSet ds)
{
var crystalReportViewer = new CrystalReportViewerPlugIn();
crystalReportViewer.PlugIn.Init(rptFileName, ds);
crystalReportViewer.PlugIn.Control.Visible = true;
var oStream = crystalReportViewer.PlugIn.ExportToStream(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat);
var byteArray = new byte[oStream.Length];
oStream.Read(byteArray, 0, Convert.ToInt32(oStream.Length - 1));
return new MemoryStream(byteArray);
}
The stream is exported as pdf:
protected virtual IHttpActionResult FinalizeExport(MemoryStream data, string name)
{
string contentType = "application/octet-stream";
name = name.GetCleanFileName();
var response = Request.CreateResponse(HttpStatusCode.OK);
response.Content = new StreamContent(data);
response.Content.Headers.Remove("content-type");
response.Content.Headers.Add("content-type", contentType);
response.Content.Headers.Remove("x-filename");
response.Content.Headers.Add("x-filename", name);
response.Content.Headers.Add("Content-Disposition", "inline; filename=\"" + name + "\"");
response.Content.Headers.Add("Content-Length", data.Length.ToString());
return ResponseMessage(response);
}
The world map is not displayed, do you have anny idea about this issue ?
