                    da.Fill(urunTable);

                    // Her bir resim için islem yapma
                    foreach (DataRow row in dataSet.Tables["resim"].Rows)

                        {

                            // Her bir uygun kayit için uygun kayit sayisini arttir

                        }
                    }

                    // Veri kaynaklarini rapora ekleme (sadece resim tablosunu kullaniyoruz)
                      ReportViewer1.ProcessingMode = Microsoft.Reporting.WebForms.ProcessingMode.Local;
                      ReportViewer1.LocalReport.ReportPath = Server.MapPath("report1.rdlc");
                      ReportViewer1.LocalReport.DataSources.Add(new ReportDataSource("urun", dataSet.Tables["urun"]));
                       ReportViewer1.LocalReport.DataSources.Add(new ReportDataSource("resim", dataSet.Tables["resim"]));
                      ReportViewer1.LocalReport.EnableExternalImages = true;
                       ReportViewer1.LocalReport.Refresh();

                    // Toplam uygun kayit sayisini bildiren mesaji göster
                    string mesaj = "alert('Toplam " + uygunKayitSayisi + " kayit bulundu.');";
                    ScriptManager.RegisterStartupScript(this, this.GetType(), "kayitBilgilendirme" + Guid.NewGuid().ToString(), mesaj, true);bir
                }
            }
        }

I have a code like this. This code works fine in Reportviever, but the images do not appear. There are two list elements, report1.rdlc. Among them, there are elements of the product dataset coming from mydataset.
In this, product dataset id and name image dataset id, product id and buyukyol buyukyol also takes the path of the image files in the pictures folder like / pictures / 1.jpg / pictures / 2.jpg. I said image in the 2nd list element. ise = Fields!buyukyol.Value I said this, the images do not appear, but if I say like this
I said = external. If I say "file://"+Fields!buyukyol.value to the value, it puts the same image in all the images that the product id is related to. In short, = Fields!buyukyol.Value. This does not work. For some reason, I added this in the field (image) main title in fx.

It seems like you’re having trouble displaying images in your RDLC report. The issue might be related to the way you’re referencing the image path in your report. When you’re setting the image source in your RDLC report, you need to ensure that the path is correctly referenced. Here’s a few things you could check: Correct Image Path : Ensure that the image paths stored in your buyukyol field are correct and the images exist at those locations. The path should be the absolute path of the image file on the server. Image Source Type : In the properties of the image in the RDLC report, make sure you’ve set the Source property to External . This tells the report viewer that the image source is an external file. MIME Type : Set the MIMEType property of the image to the correct image format (e.g., image/jpeg for .jpg files). Value Expression : The Value property of the image should be an expression that gives the full path of the image. If Fields!buyukyol.Value contains the full path of the image, you can set Value to =Fields!buyukyol.Value . If it only contains the image file name, you might need to prepend it with the path of the image folder, like ="file://" & Fields!buyukyol.Value . Remember, the path you provide should be accessible by the ReportViewer at runtime. If the images are stored in a location not accessible by the application, they will not be displayed. Thanks
