After some more testing, this has nothing to do with EnableViewState... Exception is thrown with or without ViewState

Hi Etrich,
The problem you experience is due to the new dock you create at button click event having no id which is needed for the proper functioning of the control. That is why you experience a strange behavior. Please, set id to the new dock you create.

Unfortunately, this has nothing to do with control id. This also raises an exception:
| protected void Page_Init(object sender, EventArgs e) |
| { |
| RadDock dock = new RadDock(); |
| RadDockZone1.Controls.Add(dock); |
| dock.ID = "FIXED"; |
| dock.UniqueName = "FIXED"; |
| } |
| protected void Button1_Click(object sender, EventArgs e) |
| { |
| RadDock dock = new RadDock(); |
| dock.ID = "SECOND"; |
| dock.UniqueName = "SECOND"; |
| RadDockZone1.Controls.Add(dock); |
| } |

Hello etrich,
Here is the code I tested with based on the code you provided and I was not able to reproduce any problems:
[ASPX]
[C#]
Would it be possible for you to send us a simple running page reproducing the problem you describe and steps to reproduce it.
All the best,

I don't see what more I can send you... I sent you aspx content, code behind and steps to reproduce.
When I display the page, docks shows in bottom zone. I move the dock to top zone, then hit the "make callback" button.

Hi etrich,
I was able to reproduce the problem with the last instructions you sent us. You can avoid it using this piece of code:
protected void Button1_Click(object sender, EventArgs e)
{
RadDock dock = new RadDock();
dock.ID = "SECOND";
dock.UniqueName = "SECOND";
RadDockLayout1.Controls.Add(dock);
dock.DockZoneID = "RadDockZone1";
}
Basically our advice is to use the above approach in dynamic docks scenarios and to manipulate the zone's Controls collection mainly in scenarios with static docks.
Sincerely yours,
Petya

This works fine, thank you!
There is another point we've encountered in the docks API. In the DockCommandCollection, when using the DockCommandCollection.Insert method to insert a command at a specific position, the command's RadDock property is not properly assigned and this causes side effects.
Only the DockCommandCollection.Add assigns the RadDock property.

Hi Etrich,
Insert method is not implemented by the DockCommandCollection but is inherited by the List<DockCommand> collection and that is the reason why it appears in the itellisense list of methods. I suggest using the Add method instead the Insert method. Using the Add method the dock commands are inserted in the order in which you add them.
Please, let me know if you need further assistance.
Kind regards,

It would be nice to also override the Insert of the DockCommandCollection. We have a scenario where we need to insert a command at a specific index. We are using this hack to accomplish this, using a temporary stack to use the Add method:
//commands.Insert(insertIndex, command);
//HACK: Telerik DockCommandCollection.Insert
Stack<DockCommand> insertFix_Commands = new Stack<DockCommand>();
for (int i = commands.Count - 1; i >= insertIndex; i--)
{
DockCommand insertFix_command = commands[i];
commands.Remove(insertFix_command);
insertFix_Commands.Push(insertFix_command);
}
commands.Add(command);
foreach (DockCommand commandToAdd in insertFix_Commands)
commands.Add(commandToAdd);

Hi Etrich,
We already implemented the Insert method for the DockCommandCollection and it will be available in the next update of the control - Q3 2007 SP1.
