title: html data doesn't set in my ckeditor in ajax post via json
body: <p>i have used ckeditor in my page:</p>
  
  <pre><code>&lt;%@ Register Assembly="CKEditor.NET" Namespace="CKEditor.NET" TagPrefix="CKEditor" %&gt;
  &lt;asp:Content runat="server" ID="AdminMainContent" ContentPlaceHolderID="AdminMainPlace"&gt;
                          &lt;asp:Label ID="lblDesc" runat="server" Text="توضیحات"&gt;
                          &lt;/asp:Label&gt;
                          &lt;asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server"
                              ValidationGroup="group1" EnableClientScript="true"
                              ControlToValidate="CKEditor1" ForeColor="Red" Text="*" /&gt;
                          &lt;CKEditor:CKEditorControl ID="CKEditor1" BasePath="/ckeditor/" HtmlEncodeOutput="true" runat="server" AutoGrowMinHeight="120"&gt;&lt;/CKEditor:CKEditorControl
  &lt;/asp:Content&gt;
  </code></pre>
  
  <p>when i click on grid row , it uses ajax post to get value for setting in ckeditor:</p>
  
  <pre><code> $.ajax({
          url: '&lt;%=ResolveUrl("Default.aspx/GetNews")%&gt;',
          data: JSON.stringify({ id: $("#AdminMainPlace_SelectedRow").val() }),
          type: "post",
          contentType: "application/json",
          dataType: "JSON",
          timeout: 10000,
          success: function (result) {
              if (result) {
                  $('#AdminMainPlace_txtTitle').val(result.d.NewsTitle);
                  $('#AdminMainPlace_txtSummary').val(result.d.NewsSummary);
                  $('#AdminMainPlace_imgpreview').attr('src', result.d.NewsImage);
                  $('#AdminMainPlace_NewsImage').val(result.d.NewsImage);
                  CKEDITOR.instances['AdminMainPlace_CKEditor1'].setData(result.d.NewsDescription)
              }
          }
      });
  </code></pre>
  
  <p>but after getting data ,<strong>'result.d.NewsDescription'</strong> has html data but it isn't set to my ckeditor.
  how can i solve it?</p>
