title: Inputs empty on post-back despite having values
body: <p>I'm using a telerik RadGrid, with a UserControl edit form.  When the InsertCommand event fires, I get the user control, and find edit controls on it, but there Text properties are all string.Empty.  I suspect this has something to do with ViewState, but I don't know where to begin looking.</p>
  
  <pre><code>protected void jobGrid_InsertCommand(object source, GridCommandEventArgs e)
  {
      var editControl = e.Item.FindControl(GridEditFormItem.EditFormUserControlID) as JobEditControl;
      SqlJobProvider.InsertJob(GetFieldValues(editControl));
  }
  
  private Dictionary&lt;string, object&gt; GetFieldValues(UserControl editControl)
  {
      string tb = (editControl.FindControl("aspText") as TextBox).Text;
  </code></pre>
