title: Do some ajax using jquery in asp.net
body: <p>I'm able to do very basic jquery ajax in asp.net. But I'm stuck at a point. Please see the below image.<img src="https://i.stack.imgur.com/GSmt8.png" alt="enter image description here"></p>
  
  <p>As this dialog has a file Upload control, I'm not able to figure it out how to post the data to server and do proper operation. I'm even confused How will I get the file on the server side.<br>
  In normal cases (postback one) we can access the posted file useing</p>
  
  <pre><code>FileUpload1.PostedFile.InputStream
  </code></pre>
  
  <p>But when I'm intending it to do using a <code>[WebMethod]</code> I'm not able to findout how to do this.
  Please help me with some sample or any link to tutorial.<br>
  Thanks in advance.</p>
