    <p>I recently plugged in a custom encoder (uses binary encoder to do the actual encoding and Gzip compresser to compress the byte array). It works fine. The issue now is for small message size it actually inflates the byte array. I would like to know if there is a way to avoid this. Specifically if there is a way I can apply condition compression and decompression.</p> <p>I did try to do something like - place a condition </p> <pre><code>if(buffer.Count &lt;= 5000) skip compression </code></pre> <p>But the problem is on the other end decompression will happen even if the bytes are not compressed. I hope this makes sense.</p> <p>Following are the functions where compression and decompression happens (code snippet from CompactMessageEncoder)</p> <pre><code>public override Message ReadMessage(ArraySegment&lt;byte&gt; buffer, BufferManager bufferManager, string contentType) { ArraySegment&lt;byte&gt; decompressedBuffer = DecompressBuffer(buffer, bufferManager); LogWrite("Decompressed from {0} bytes to {1} bytes", buffer.Count, decompressedBuffer.Count); Message returnMessage = _innerEncoder.ReadMessage(decompressedBuffer, bufferManager); returnMessage.Properties.Encoder = this; return returnMessage; } public override ArraySegment&lt;byte&gt; WriteMessage(Message message, int maxMessageSize, BufferManager bufferManager, int messageOffset) { var buffer = _innerEncoder.WriteMessage(message, maxMessageSize, bufferManager, messageOffset); var compressedBuffer = CompressBuffer(buffer, bufferManager, messageOffset); LogWrite("Compressed from {0} bytes to {1} bytes", buffer.Count, compressedBuffer.Count); return compressedBuffer; } </code></pre>

    1. COcould you add a custome header to those messages that were compressed? http://stackoverflow.com/questions/964433/how-to-add-a-custom-header-to-every-wcf-calls

    2. CO@Mitch: This might not work. Since I will have to add Lets say I add custom header to the Message class and compress it in WriteMessage() function. In the ReadMessage() I will have to decompress it before getting the Message class and reading the header.

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.
