Hi I have a page that allows me to upload photo. Then when i click upload...the photo has been approved. But when i want to display it in gridview. The column that the image must appear it gives me "System.Byte[]" instead of an image. Help :)
Here's my code:
<%@ Page Language="C#" Debug="true" %>
<%@ Import Namespace="System" %>
<%@ Import Namespace="System.Data" %>
<%@ Import Namespace = "System.Data.SqlClient" %>
<%@ Import Namespace= "System.Data.OleDb" %>
<script runat="server" type="text/c#">
protected void btnUpload_Click(object sender, EventArgs e)
{
{
byte[] imageSize = new byte
[FileUpload1.PostedFile.ContentLength];
HttpPostedFile uploadedImage = FileUpload1.PostedFile;
uploadedImage.InputStream.Read
(imageSize, 0, (int)FileUpload1.PostedFile.ContentLength);
// Create SQL Connection
OleDbConnection con = new OleDbConnection();
con.ConnectionString = ConfigurationManager.ConnectionStrings["recordsConnectionString"].ConnectionString;
// Create SQL Command
OleDbCommand cmd = new OleDbCommand();
cmd.CommandText = "INSERT INTO PendingRecords([Image])" + " VALUES (@Image)";
cmd.CommandType = CommandType.Text;
cmd.Connection = con;
OleDbParameter UploadedImage = new OleDbParameter
("@Image", OleDbType.VarBinary, imageSize.Length);
UploadedImage.Value = imageSize;
cmd.Parameters.Add(UploadedImage);
con.Open();
cmd.ExecuteNonQuery();
GridView1.DataSourceID = "";
GridView1.DataSource = SqlDataSource1;
GridView1.DataBind();
con.Close();
}
}
</script>
