    <p>I am working on an API kind of project,</p> <p>I have wrote a WebMethod <em>(not exactly. I am using MVC to create REST like API)</em></p> <pre><code>public UploadFileImage(string employeeId, byte[] imageBytes, string imageName) { // saves the imagebyte as an image to a folder } </code></pre> <p>the web service would be consumed by a web app, or windows or even iphone or such portable stuffs. I am testing my web service using a web app, by simple httpPost.</p> <pre><code>string Post(Uri RequestUri, string Data) { try { HttpWebRequest request = HttpWebRequest.Create(RequestUri) as HttpWebRequest; request.Method = "POST"; request.ContentType = IsXml.Checked ? "text/xml" : "application/x-www-form-urlencoded"; byte[] bytes = Encoding.ASCII.GetBytes(Data); Stream os = null; // send the Post request.ContentLength = bytes.Length; //Count bytes to send os = request.GetRequestStream(); os.Write(bytes, 0, bytes.Length); HttpWebResponse httpWebResponse = (HttpWebResponse)request.GetResponse(); StreamReader streamReader = new StreamReader(request.GetResponse().GetResponseStream()); return streamReader.ReadToEnd(); } catch (Exception ex) { return ex.Message; } } </code></pre> <p>This code works fine for evey method like, AddEmployee, DeleteEmployee etc. THe parameter Data is of form "Id=123&amp;name=abcdefgh&amp;desig=Developer",</p> <p>How I call any other function is Post(new Uri("http://localhost/addemployee"),"name=abcd&amp;password=efgh")<br> where post is the function i wrote. </p> <p>All good for all functions. Except that I dont know how to consume the above mentioned function UploadFileImage to upload an image?</p> <p>Thanks </p>

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.
