Hi,

I have read the http://help.nevron.com/dotnetvision/UsersGuide_DockingPanels_Layout_Presistency.html documentation pretty thoroughly and I'm still having problems persisting my layout.

The specific problem I am having is that the ResolveClientEventHandler does not appear to call the specified method when I call Load on the NDockingFrameworkState object. I've put debug.print statements in the _layout_Restore_ResolveDocumentClient method to verify this. I must be doing something wrong, but I cannot figure it out. One interesting thing to note is that I see a quick flash of what appears to be a splitter which disappears very quickly.

Here is an example of how I create and add panels. I pay special attention to setting the text and key properties of the panels:

private void addControlToRootZone(string text, string key, Control control, DockStyle dockStyle, bool insertAtBeginningVsEnd)
{
 NDockingPanelHost panelHost = _populatePanelHost(text, key, control, dockStyle);

 if (insertAtBeginningVsEnd)
  nDockManager1.RootContainer.RootZone.AddChild(panelHost, 0);
 else
  nDockManager1.RootContainer.RootZone.AddChild(panelHost, nDockManager1.RootContainer.RootZone.Children.Count);
}
private NDockingPanelHost _populatePanelHost(string text, string key, Control control, DockStyle dockStyle)
{
 control.Tag                             = key;
 control.Dock                            = DockStyle.Fill;

 NDockingPanel panel                     = new NDockingPanel();
 panel.Key                               = key;
 panel.Text                              = text;           
 panel.Dock                              = dockStyle;
 panel.Controls.Add(control);

 NDockingPanelHost panelHost             = new NDockingPanelHost();                       
 panelHost.AddChild(panel);

 return panelHost;
}

Here is an example of how I save the layout:

static public void Save_ApplicationLayout(string sFilename, NDockManager nDockManager)
{
 NDockingFrameworkState state    = new NDockingFrameworkState(nDockManager);           
 state.Format                    = Nevron.Serialization.PersistencyFormat.XML;
 state.PersistStyles             = true;
 state.PersistDocuments          = true;
 state.Save(sFilename);
 state.Dispose();
 state                           = null;
}

Here is an example of how I attempt to restore the layout. The sFilename variable value is identical to one used in the Save_ApplicationLayout. However, the ResolveClientEventHandler is never called/activated/etc:

private void Restore_ApplicationLayout(string sFilename)
{
 NDockingFrameworkState state    = new NDockingFrameworkState(nDockManager1);        
 state.Format                    = Nevron.Serialization.PersistencyFormat.XML;
 state.ResolveDocumentClient     += new ResolveClientEventHandler(_layout_Restore_ResolveDocumentClient);
 bool worked                     = state.Load(sFilename);    // <<--== The _layout_Restore_ResolveDocumentClient method is never called.         
 state.Dispose();
 state                           = null;
}
void _layout_Restore_ResolveDocumentClient(object sender, DocumentEventArgs e)
{         
 System.Diagnostics.Print("The _layout_Restore_ResolveDocumentClient method was called."); // <<--== This never occurs.
 string type                                  = e.Document.Text;

 switch (type)
 {
  case ControlKeyNames.StatusControl:
   Documents.statusDocument statusControl1 = getStatusControl();
   e.Document.Client                       = statusControl1;
   statusControl1.Start();
   Application.DoEvents();
   break;
 }

 e.Handled = true;
}
