hi Everybody,
I am exporting radgrid into pdf. But on the same time, I want to add an jpg image into same pdf, by converting into bytes. In debugging it is showing all total bytes into newarr, and even it adds same total kbs into resultset pdf file, but it does not show that additional image into result pdf file. Please do help me.

MemoryStream chartStream;// it contain image in chartStream on button click and after button click execute RadGrid1_GridExporting.
protected void RadGrid1_GridExporting(object source, GridExportingArgs e)
        {
            using (FileStream fs = File.Create(FILEPATH))
            {
                byte[] chartbytes = System.Text.Encoding.Default.GetBytes(e.ExportOutput);
                byte[] imagebytes = chartStream.ToArray();
                byte[] newarr;
                newarr = chartbytes.Concat(imagebytes).ToArray();
                fs.Write(newarr, 0, newarr.Length);
            }
        }

Hi Andrey,
Thanks for this. I have already gone through with this example, but in this image is in the same radgrid control. I have two different control and both are not in each other.

Thanks

Hi Munish,

It is not possible to just concatenate the image binary to the PDF binary. Use this approach if you need to export RadChart to PDF.
