title: Can I call a server-side method using javascript without causing a postback?
body: <p>I have JavaScript code that calls a method in ASP.NET. Basically, I have a <code>SqlDataSource</code> connected to a <code>GridView</code>, and I want to change the <code>SelectCommand</code> of the <code>DataSource</code> without causing a postback.</p>
  
  <p>Right now, I am using <code>__dopostback</code> method, but as I said I don't want the page to reload. I just want the <code>GridView</code> to update. Is this possible?  </p>
