title: MVC3 Pop New Window/View and Send Entered Data Back to Original Open Window/View When Done
body: <p>In my view a user searches a dropdown that contains a list of "Prescribers" if the Prescriber
  does not exist in the Database, they have a button that pops a window containing an "Add New
  Prescriber" View.  How can I gather the primary key field data of the new user entered Prescriber and pass it back/repopulate the dropdown to contain the new Prescriber without reloading the original view and losing information entered in other fields?</p>
  
  <pre><code>&lt;div class="editor-label"&gt;
              @Html.LabelFor(model =&gt; model.DEA_Number, "Prescriber's DEA #")
          &lt;/div&gt;
          &lt;div class="editor-field"&gt;
              @Html.DropDownList("DEA_Number", String.Empty)
              @Html.ValidationMessageFor(model =&gt; model.DEA_Number)
          &lt;/div&gt;
  
          &lt;div&gt;
          &lt;p&gt;Prescriber Not in System? - Click to Add
          &lt;input type="button" name = "ClickMe" value="Add New Prescriber" onclick= "javascript:window.open('/Prescriber/Create/','Customer Search',height='window.screen.height - 100', width='200',left='window.screen.width - 250' ,top='10',status='no',toobar='no',resizable='yes',scrollbars='yes')"/&gt;
          &lt;/p&gt;
          &lt;/div&gt;
  </code></pre>
