Hi,

I'm using Q2 2009 SP1. When I call RadDock.SaveToXml(), and try and reload using RadDock.LoadFromXML() I get a reflection runtime error ; "No parameterless constructor defined for this object.".

For info, my XML file is shown here
  <?xml version="1.0" encoding="utf-8" ?>   
<RadDock Orientation="Horizontal" BackColor="191, 219, 254" TabIndex="0" TabStop="False">  
  <DocumentManager DocumentInsertOrder="InFront" />   
<Controls> 
<Telerik.WinControls.UI.Docking.ToolTabStrip BackColor="191, 219, 254" SelectedIndex="0" Size="200, 98" Location="0, 0" Name="" TabIndex="1" TabStop="False">  
  <SizeInfo SplitterCorrection="0, 0" AutoSizeScale="0, 0" />   
<Controls> 
  <Telerik.WinControls.UI.Docking.HostWindow Name="ToolWindow1" Text="Registration Group" Size="198, 69" Location="1, 28" />   
  </Controls> 
  </Telerik.WinControls.UI.Docking.ToolTabStrip> 
<Telerik.WinControls.UI.Docking.ToolTabStrip BackColor="191, 219, 254" SelectedIndex="0" Size="200, 99" Location="0, 101" Name="" TabIndex="2" TabStop="False">  
  <SizeInfo SplitterCorrection="0, 0" AutoSizeScale="0, 0" />   
<Controls> 
  <Telerik.WinControls.UI.Docking.ToolWindow CloseAction="CloseAndDispose" Text="Day Register" ToolCaptionButtons="AutoHide" DocumentButtons="None" Name="toolWindow1" Size="198, 70" Location="1, 28" />   
  </Controls> 
  </Telerik.WinControls.UI.Docking.ToolTabStrip> 
  </Controls> 
  </RadDock>

I have also been experiencing the same problem, does anyone know either the reason why this happens or a solution?

Hello Matt,

This is a known issue and it will be addressed in Q3 2009. For the time being, you can use the following approach to dock a form/user control:
FormDocument document = new FormDocument();     
FormTool tool = new FormTool();     
    
document.FormBorderStyle = FormBorderStyle.None;     
document.TopLevel = false;     
document.Dock = DockStyle.Fill;     
document.Show();     
    
tool.FormBorderStyle = FormBorderStyle.None;     
tool.TopLevel = false;     
tool.Dock = DockStyle.Fill;     
tool.Show();     
    
DocumentWindow documentWin = new DocumentWindow();     
ToolWindow toolWin = new ToolWindow();     
    
documentWin.Controls.Add(document);     
toolWin.Controls.Add(tool);                 
    
this.radDock1.AddDocument(documentWin, DockPosition.Right);     
this.radDock1.DockWindow(toolWin, DockPosition.Left);    
 

I hope this helps. If you have additional questions, feel free to contact me.

Kind regards,

This doesn't actually answer my question.  How can I dynamically load the dock windows from my saved XML file?

Hi Matt,

The issue that we know arises when you dock a form/usercontrol using the DockControl method and then save and try to load the RadDock layout. If you want to workaround this exception, you should use the API which I demonstrated above. When the forms/controls are docked through this API, there are no issues on my side when I save and load the RadDock layout.

If your scenario is different, please open a new support ticket and send me a sample project. This will allow me to help you further.
