Attachments not storing properly in database

[Baal]

I have radUpload control in my page from which users can only upload images.

<telerik:RadUpload ID="ruImage" runat="server" InitialFileInputsCount="1" ControlObjectsVisibility="None" AllowedMimeTypes="image/bmp,image/gif,image/jpeg,image/pjpeg,image/tiff,image/x-png" />

I am using the following code in my codebehind to upload the images to the database.

if (ruImage.UploadedFiles.Count > 0)
{
    AppImages oImage = null;

    foreach (UploadedFile theFile in ruImage.UploadedFiles)
    {
        string fileName = theFile.FileName;
        fileName = fileName.Substring(fileName.LastIndexOf(@"\")).Replace(@"\", "");

        byte[] myBytes = new byte[theFile.ContentLength];
        theFile.InputStream.Read(myBytes, 0, theFile.ContentLength);


        oImage = new AppImages();

        oImage.AppId = appId;
        oImage.FileName = fileName;
        oImage.FileSize = theFile.ContentLength;
        oImage.FileType = theFile.ContentType;
        oImage.Attachment = myBytes;
        oImage.LastUpdatedBy = UserName;
        oImage.Insert();

        oImage = null;
    }
}

The column Attachment in the AppImages table is of type IMAGE. When I debug the code, everything is good as it should be except the content of myBytes. every single element of the array will have 0 as its value. Even when I check the database (I'm using SQL Server 2008), the content of the Attachment column will be 0x000...

Now when I try to load the images to the grid (I have GridBinaryImageColumn), I get the following error from the IE8 debugger:
Error: Sys.WebForms.PageRequestManagerServerErrorException: The provided binary data may not be valid image or may contains unknown header

When I force the page to load, I get the following error:

Parameter is not valid.

I've searched the net for this error but coulnd't find any help. Have you guys seen anything like this?

Thanks.

The problem while uploading the file was that somehow the position of the InputStream wasn't at 0. So I added theFile.InputStream.Position = 0 before populating the byte array with the data from the InputStream and it worked fine.
