Crystal Reports Display Images From Database in Asp.Net



Description:-

                 In this Example we define that how to Display Image in crystal Report Retrive From database.for example we have one record with name,address and third is it's Image. so that's type of data how we can Display in CrystalReport when user click on each row of Gridview The same record are display in Report and you can also navigate the record printing record in report.

In Simple you Bind the data in CrystalReport then it will Display Name of the Image not Image so avoid this Sitution we Have to Convert this Image in ByteArray If DataType of the Photo or Image Coloumn in database is String if DataType is Image then you did not Require to Covert into ByteArray Because It also Return ByteArray.

If Your Coloumn(photo,iamge etc..) Defines with String DataType then First You Have to Convert it into ByteArray. To Convert this Code is Here

public static byte[] ReadImageFile(string PostedFileName, string[] filetype)
    {
        bool isAllowedFileType = false;
        try
        {
            FileInfo file = new FileInfo(PostedFileName);

            strFile_Name = file.Name;

            foreach (string strExtensionType in filetype)
            {
                if (strExtensionType == file.Extension)
                {
                    isAllowedFileType = true;
                    break;
                }
            }
            if (isAllowedFileType)
            {
                FileStream fs = new FileStream(PostedFileName, FileMode.Open, FileAccess.Read);

                BinaryReader br = new BinaryReader(fs);

                byte[] image = br.ReadBytes((int)fs.Length);

                br.Close();

                fs.Close();

                return image;
            }
            return null;
        }
        catch (Exception ex)
        {
            throw ex;
        }

    }


To Call this Function Pass Parameter Like this

Byte[]  bt = ReadImageFile(s, new string[] { ".GIF", ".gif", ".jpg", ".bmp", ".jpeg" });
