Okay... Got your point. Apply the below properties and try In RDLC report Click the image control and set the MIME type to image/jpeg Set the source to Database Set the value property from the Parameters value Rest the souce snippet (in question) seems to be working good Do apply above properties and do let me know, if it solves your issue You can test your base64string from the below link https://codebeautify.org/base64-to-image-converter Good Luck

Images in your datagrid might be depicted from any file path, right? then you can directly send the path to Report parameters. Documents shown all types of putting image in report, kidly recheck with your design https://docs.microsoft.com/en-us/previous-versions/sql/sql-server-2008-r2/ms156388(v=sql.105)?redirectedfrom=MSDN

Have you set the MimeType to image in rdlc. It might be not a valid bytes of image. https://www.skotechlearn.com/2019/01/pass-parameter-with-image-in-RDLC-Report-Viewer-in-ASP-Net.html?m=1

My image on "datagridview" comes from an XML file that has a binary image record, when loaded into "datagridview" I convert it with this code : private void gvData_CellFormatting( object sender, DataGridViewCellFormattingEventArgs e) { if (e.ColumnIndex == 13) { DataGridViewCell dgcell = gvData.Rows[e.RowIndex].Cells[e.ColumnIndex]; if (dgcell.Tag != null ) { string imgCode = dgcell.Tag.ToString(); byte [] bytes = Convert.FromBase64String(imgCode); //e.Value = bytes; Bitmap bmp2 = null ; using (MemoryStream m = new MemoryStream(bytes)) { // //this construct is needed if we want to Close and Dispose the MemoryStream Bitmap bmpTmp = new Bitmap(m); bmp2 = new Bitmap(bmpTmp.GetThumbnailImage(200, 100, null , IntPtr.Zero)); bmpTmp.Dispose(); e.Value = bmp2; m.Close(); } } }

Yes , but your line of code uses an image from the location, in my case the image should be called from datagridview from Cells [12] paramtr(3) = New ReportParameter( "ParaCustImg" , "file:///" + "C:\SKOTechLearn.jpg" )
