<p>I ended up using FJCore <a href="http://code.google.com/p/fjcore/" rel="nofollow noreferrer">http://code.google.com/p/fjcore/</a> to encode my WriteableBitmap into JPEG and then converted that to BASE64 using code I found at this question <a href="https://stackoverflow.com/questions/1139200/using-fjcore-to-encode-silverlight-writeablebitmap">Using FJCore to encode Silverlight WriteableBitmap</a> THANKS!. Then in turn converted that out to a byte[] array and sent it to MVC using your code and now its working great. I'm pretty new at all this stuff and didn't quite understand the encoding process enough before. Below is the code I used for this. Thanks again for your help!</p> <pre><code> private static string GetBase64Jpg(WriteableBitmap bitmap) { int width = bitmap.PixelWidth; int height = bitmap.PixelHeight; int bands = 3; byte[][,] raster = new byte[bands][,]; for (int i = 0; i < bands; i++) { raster[i] = new byte[width, height]; } for (int row = 0; row < height; row++) { for (int column = 0; column < width; column++) { int pixel = bitmap.Pixels[width * row + column]; raster[0][column, row] = (byte)(pixel >> 16); raster[1][column, row] = (byte)(pixel >> 8); raster[2][column, row] = (byte)pixel; } } ColorModel model = new ColorModel { colorspace = ColorSpace.RGB }; FluxJpeg.Core.Image img = new FluxJpeg.Core.Image(model, raster); MemoryStream stream = new MemoryStream(); JpegEncoder encoder = new JpegEncoder(img, 90, stream); encoder.Encode(); stream.Seek(0, SeekOrigin.Begin); byte[] binaryData = new Byte[stream.Length]; long bytesRead = stream.Read(binaryData, 0, (int)stream.Length); string base64String = System.Convert.ToBase64String(binaryData, 0, binaryData.Length); return base64String; } private void SendImage() { var client = new WebClient(); var uri = new Uri("http://localhost:4600/GuestBadge/GetCameraImage"); client.OpenWriteCompleted += (sender, e) => { var buffer = (byte[])e.UserState; e.Result.Write(buffer, 0, buffer.Length); e.Result.Close(); }; client.OpenWriteAsync(uri, "POST", Convert.FromBase64String(GetBase64Jpg(SnapShot))); } </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
