尚未为此报告设置 enable externalimages 属性？

Question

I am trying to add an external photo as the logo along with the report on the report.rdlc file. I have this error

The enable externalimages property has not been set for this report

?

Here is my code.

 try
{
    this.pedidosTableAdapter.Connection.ConnectionString = con.MysqlConnect();

    this.pedidosTableAdapter.Fill(this.fabricacaoDataSet8.pedidos, Pages.relatorios.num);
    this.reportViewer1.RefreshReport();
}
catch { }

// for external image
this.reportViewer1.LocalReport.EnableExternalImages = true;
ReportParameter parm = new ReportParameter();
parm=(new ReportParameter("path", @"C:\logo.jpg",true));
this.reportViewer1.LocalReport.SetParameters(parm);
this.reportViewer1.Refresh();

Answer 1

I have experience when you enable external images using Code, it works on local / development environment but while deployment on server it does not works and reports raise error:

"The enable external images property has not been set for this report"

In order to solve this issue, use EnableExternalImages="true" property in ASPX or design file where you are using ReportViewer Control and it will work perfectly.

Answer 2

The problem here actually is, that you're calling this.reportViewer1.RefreshReport(); before setting this.reportViewer1.LocalReport.EnableExternalImages = true; .

The order is important here.

Answer 3

As mentioned here , the path of the image must be in URL format, ie @"file:///C:\\logo.jpg"

Or you can try

var filepath = new Uri("C:\logo.jpg");
var path = new ReportParameter("Path", filepath.AbsolutePath);
this.reportViewer1.LocalReport.SetParameters(new ReportParameter {Path = path});

Answer 4

I hope this image is a help in your Windows Application.Activate your Reportviewer->Properties->LocalReport->EnableExternalImage and set it to True

Answer 5

For WinForm Applications, below code will works well.

string templateImage = Application_Path + @"\Images\ReportLogo.jpg";
rvRptContainer.LocalReport.EnableExternalImages = true;
rvRptContainer.LocalReport.SetParameters(new ReportParameter("ReportLogo", "File:\\" + templateImage));

For ASP.Net Applications, Do the following:

ReportViewer1.LocalReport.EnableExternalImages = true;

    string imagePath = new Uri(Server.MapPath("~/images/Mudassar.jpg")).AbsoluteUri;

    ReportParameter parameter = new ReportParameter("ImagePath", imagePath);

    ReportViewer1.LocalReport.SetParameters(parameter);

    ReportViewer1.LocalReport.Refresh();

Answer 6

Nothing worked for me, But simply this worked

        LocalReport localReport = new LocalReport();
        localReport.ReportPath = HostingEnvironment.MapPath("~/Reports/myreport.rdlc");
        localReport.EnableExternalImages = true;
        localReport.EnableHyperlinks = true;
