  Posted on Mar 2, 2010 (permalink)

  Continuing on the progress we made in the previous post, the next step is reverting a page in a checked in, Draft state back to its previous version before changes were made
  
  I've spent several hours experimenting with no luck. The documentation offers no guidance. I'm wondering how you would approach it.
  
  We know that the VersionManager doesn't work on page items, however, Rodoslav mentioned a page "copy" method for 3.7 SP2. I'm running that version, if that method is useful.
  
  Thanks,
  Jeff

  Hi Jeff,
  
  1. The forum post shows how to use VesionManager and working with object's versions.
  
  2. You can use the UI to perform Restore. Note that the highlighted button should be visible and not commented.
  
  

  <asp:GridView ID="GridView1" AllowPaging="true" PageSize="20" AutoGenerateColumns="false" GridLines="none" CssClass="listItems history" runat="server">

          <Columns>

              <asp:TemplateField>

                  <ItemTemplate>

                      <asp:HyperLink ID="PreviewLink" runat="server"><asp:Literal runat="server" Text="<%$Resources:View %>"></asp:Literal></asp:HyperLink> 

                      <asp:LinkButton ID="RollbackButton" runat="server"><asp:Literal runat="server" Text="<%$Resources:RollBack %>"></asp:Literal></asp:LinkButton>

                      <asp:LinkButton ID="RestoreButton" runat="server"><asp:Literal ID="Literal1" runat="server" Text="Restore"></asp:Literal></asp:LinkButton>

                  </ItemTemplate>

                  <ItemStyle CssClass="gridActions" />

              </asp:TemplateField>

              <asp:BoundField DataField="Version" HeaderText="<%$Resources:Version %>"><ItemStyle CssClass="gridContentTitle" /></asp:BoundField>

              <asp:BoundField DataField="Stamp" HeaderText="<%$Resources:Date %>" HeaderStyle-CssClass="GridHeader_SiteFinity" DataFormatString="<%$Resources:VersionDateFormat %>" HtmlEncode="false" />

              <asp:BoundField DataField="Modifier" HeaderText="<%$Resources:Author %>" HeaderStyle-CssClass="GridHeader_SiteFinity" />

              <asp:BoundField DataField="Theme" HeaderText="<%$Resources:Theme %>"><ItemStyle /></asp:BoundField>

          </Columns>

      </asp:GridView>

  
  programmatically restoring a page
  
  

  IStagedPage staged = this.iPage.GetVersion(version);

  staged = staged.CheckOut();

  staged.CheckIn();

  Thanks for the quick response.
  
  Can I get a complete code sample? I'm not sure how to apply it since ICmsPage.Staged is a read-only property.

  Hi Jeff,
  
  Below is a sample code that will do restore - a new version will be created( copy )
  
  

  // pass the page and its version to a private method

   

  private void Restore(int version, ICmsPage p)

  {

   

      IStagedPage staged = p.gGetVersion(version);

      staged = staged.CheckOut();

      staged.CheckIn();

      OnRestore(EventArgs.Empty);

  }

  Hi Ivan,
  
  I'm back.
  
  The latest sample isn't working. No new version of the page is created and the current version is unchanged.
  
  Is there something in the "OnRestore" event that finishes the job? I'm not privy to what's in that event or how to call it.
  
  Thanks,
  Jeff

  Hi Jeff,
  
  OnResote is used when the Grid is rebind. I slightly modified the code at my end and it is working correctly. It performs restore of version 3 for the specified page.
  
  

  var manager = new CmsManager();

  ICmsPage p = (ICmsPage)manager.GetPage(new Guid("797aa331-7edf-4dc1-9c92-80e8ccf12bcd"), true);

  IStagedPage s = p.GetVersion(3);

  IStagedPage st = s.CheckOut();

  st.CheckIn();

  Ivan,
  
  You have given me the same code sample (from a functional standpoint) three times in a row. It doesn't work.
  
  Can you please test this out yourself so we don't keep going around in circles?
  
  Thanks,
  Jeff

  Hello Jeff,
  
  I have tested the code several times. Take a look at the attached video prepared for your convenience. I am not sure why the code does not work for you. Note that this code restore - copy a page version by creating a new one.

  I see that it is working for you and I appreciate that you even went through the trouble to produce a video. At this point, I guess we just need to figure out why I don't get the same results.

  
  

  I couldn't tell from the video if you have workflow enabled. If it is, I could not see the page status. In my case, I am trying to go from a "Draft" status to a previous version.

  
  

  Can you confirm that this code sample works under the same conditions for you?

  
  

  Also, I see you page "Rollback" and "Restore" links next to every version on the History page. I only have Roll back. Could this be factor? Does my lack of a Restore link mean there's a feature that I haven't enabled that could be preventing the code from working?

  
  

  Thanks for your continued efforts on this issue.

  
  

  Jeff
