title: User Control on a asp.net page doesn't get reinitialized when another instance of the page is created
body: <p>I have a C# website that has a a user control where I initialize a series of private variables at the top of the user control:</p>
  
  <pre><code>using System.IO;
  
  namespace FF.Core
  {
  
      public partial class _Job : System.Web.UI.UserControl
      {
          private static long _JobID = 0;
          private static string _JobNumber = String.Empty;
  </code></pre>
  
  <p>I have dragged this user control on an .aspx page the mark up is as follows:</p>
  
  <pre><code>&lt;%@ Register Src="_Job.ascx" TagName="_Job" TagPrefix="uc1" %&gt;
  
  &lt;uc1:_JobDataEntry ID="_Job" runat="server" /&gt;
  </code></pre>
  
  <p>My application will launch multiple pages that contain this user control.  It appears that after the first instance is launched the user control is not reinitialized ie the _JobID is not set back to 0 instead it contains the value of the previous loaded _JobID.  I was under the impression because I'm launching a new page the _JobID would be set back to 0.  I could initialize my variables in page load but I wanted to understand why this is happening and understand the best way to reuse a user control.  Each of my new pages is being launched in a new browser window "target=_blank"  </p>
  
  <p>Thanks ! </p>
