title: Get the values of a cell in a selected row of a RadGrid on client Side
body: <p>Hey there everyone, I'm hoping there is a simple fix for this, but I would accept a complicated one after messing around with it for the last day and a half!</p>
  
  <p>I am putting together a module that will drop into a DotNetNuke portal and I'm populating a Telerik RadGrid with data. I have followed every tutorial and example I can find, but the result keeps coming back with "object Object", "null", or "undefined". </p>
  
  <p>I need to: 
  1) get the value of the "BookingID'" column for each row that is selected 
  2) pass the value into a url string that opens up in a RadWindow. </p>
  
  <p>I'm trying to do all of this using javascript, but if you know a better way, I'm down for anything at this point. </p>
  
  <p>Here is my current JavaScript and a stripped down radGrid: </p>
  
  <pre><code> ///Javascript///
  
  function gup(name) {
      name = name.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]");
      var regexS = "[\\?&amp;]" + name + "=([^&amp;]*)";
      var regex = new RegExp(regexS);
      var results = regex.exec(window.location.href);
      if (results == null) return "";
      else return results[1];
  }
      function ShowEditForm() {
          var tab = gup('tabid')
          var mid = gup('mid').replace(/#/, '')
          var masterTableView = $find("perDiemBookingsRadGrid").get_masterTableView();
          var id = masterTableView.get_selectedItems()[0].getDataKeyValue('BookingID');
  
          window.radopen("/Default.aspx?tabid=" + tab + "&amp;ctl=multiEdit&amp;mid=" + mid + "&amp;SkinSrc=[G]Skins/Blue-NCPP/Plain&amp;BIDs=" + id, "RadWindow3");
      }
  </code></pre>
