register DockPositionChanged for codebehind dynamically

[Juan]

hi, i'm create a RadDock dynamically of this form:

Protected Function creardock() As RadDock
        Dim newdock As New RadDock

        newdock.UniqueName = Guid.NewGuid().ToString().Replace("-", "a")
        newdock.ID = String.Format("RD{0}", newdock.UniqueName)
        newdock.EnableAnimation = True
        newdock.EnableDrag = True
        newdock.DockMode = DockMode.Docked
        newdock.DockHandle = DockHandle.Grip
        newdock.Resizable = False
        newdock.Width = Unit.Percentage(50)
        newdock.AutoPostBack = True
        newdock.Collapsed = False
        newdock.Skin = "Black"
        AddHandler newdock.DockPositionChanged, New DockPositionChangedEventHandler(AddressOf RadDock_DockPositionChanged)

        Return newdock
    End Function

this is a function that i need register for each raddock created:

    Protected Sub RadDock_DockPositionChanged(ByVal sender As Object, ByVal e As DockPositionChangedEventArgs)
        Dim docksel As RadDock = DirectCast(sender, RadDock)
        docksel.DockZoneID = e.DockZoneID
        docksel.Index = e.Index

        lbl.Text = "dock_zone_obj: " & docksel.DockZoneID & " - dock_zone_des: " & e.DockZoneID & "<br />" & _
                   "dock_index_obj: " & docksel.Index & " - dock_index_des: " & e.Index
    End Sub

Each raddock that is returned for the function creardock(), i need add to a raddockzone that too is created dynamically, the problem is that the event RadDock_DockPositionChanged not being registered, the addition to the raddockzone is as follows:

Dim mizona As RadDockZone = crearradzone()

Dim midock As RadDock = creardock()
 mizona.Controls.Add(midock)

this is the function that return the new raddockzone

 Protected Function crearradzone() As RadDockZone
        Dim newraddockzone As New RadDockZone()
        newraddockzone.MinWidth = Unit.Percentage(98)

        Return newraddockzone
    End Function

note that the creation of the Raddockzone and the Raddock depend on a dynamic creation of tables rows and columns have many records in a DB, the only fixed in the file .aspx is a RadDockLayout and a panel which I add the table or tables dynamically created

help me, i need know if there is any mistake in any function in my code, thanks.

Hello Juan,

From the source code you provided I can see that you set the ID and the UniqueName of the dock by generating a GUID:
      newdock.UniqueName = Guid.NewGuid().ToString().Replace("-", "a")
      newdock.ID = String.Format("RD{0}", newdock.UniqueName)
Do you always generate a new ID when creating the dock dynamically? If this is the case then the RadDockLayout will not maintain the dock state correctly, and the server-side events of the dock might not be raised. Please note that the RadDock must have one and the same ID and UniqueName throughout the application's life-cycle.
So my recommendation is to have a separate method that will be used to create the RadDock from the state. As a reference you could use our MyPortal demo. Note that we have two functions for creating docks:
        Private Function CreateRadDockFromState(state As DockState) As RadDock
        Private Function CreateRadDock() As RadDock
