  Is there a way (either server-side, or preferably client-side) to hook the the expand/collapse event of dock object?  I want to save it's expanded/collapsed state in the user's profile in ASP.NET 2.0. 
  
  Thanks.

  Hello Chris,
  
  You must add the Collapse and Expand commands. After that, you must set their  AutoPostBack property to true.
  
  

  <radDk:RadDockableObject ID="RadDockableObject1" runat="server" Text="1" OnCommand="RadDockableObject1_Command">

  <Commands>

  <radDk:RadDockableObjectCommand AutoPostBack="True" Enabled="False" Name="Expand"  ToolTip="Expand" />

  <radDk:RadDockableObjectCommand AutoPostBack="True" Name="Collapse"  ToolTip="Collapse" />

  </Commands>

  </radDk:RadDockableObject>

  
  Also you must add a handler in code behind to the RadDockableObject  (OnCommand="RadDockableObject1_Command)
  
  and do something in code behind:
  
  

  protected void RadDockableObject1_Command(object sender, EventArgs e)

  {

  //doSomething

  }

  Hello,
  
  As you might have noticed, I've been working with the Docking stuff this weekend.  Cool stuff, by the way!
  
  Is there a way to do a Client-Side event here?
  
  When a user makes a change to the layout of their page, I'm making a link to save their changes visible (which was, of course, previously hidden).  I'd like to make this link available for when someone expands or collapses a window, too.  I don't want to do a postback.
  
  I can probably just make this link always visible, and I might go that route, but I'd like to see if this is possible, first.
  
  Thanks.

  Hi Barry,
  
  You must add onclientcommand="showlink" to expand and Collapse commands:
    <radDk:RadDockableObjectCommand  Name="Collapse"  ToolTip="Collapse" onclientcommand="showLink"/> where showlink function will show the link using javascript.
  A simple example using custom commands and handling client side events, you can find at:

  If you are having issues with the EventArgs e, cast it to its correct type:
  

  protected void RadDockingZone1_OnCommand(object sender,  EventArgs e)

  {

  RadDockableObjectCommandEventArgs e2 = e as RadDockableObjectCommandEventArgs;

  switch (e2.Command.Name)

  {

  case "Expand":

  //Do something

  break;

  }

  }
