Hristo,
Thanks for sending me that project. I wasn't thinking clearly before - I understood that it wasn't possible to obtain the DockPosition while a DockWindow was in autohide mode, but I also didn't realize that whenever a user docked a floating window, its DockState would default to 'Docked' rather than 'AutoHide', so I could just grab the DockPosition while the DockWindow was 'Docked'.
I actually submitted the suggested workaround but found that it wouldn't work if a user decided to change the DockPosition of any of the windows :)
Here's the code that I used:
Private Sub RadForm1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
RadDock1.DockWindow(ToolWindow2, DockPosition.Right)
RadDock1.AutoHideWindows(New DockWindow() {ToolWindow2}, AutoHidePosition.Right)
ToolWindow2.Tag = DockPosition.Right
RadDock1.AutoHideWindow(ToolWindow1)
ToolWindow1.Tag = DockPosition.Left
End Sub
Private Sub RadDock1_FloatingWindowCreated(sender As Object, e As FloatingWindowEventArgs) Handles RadDock1.FloatingWindowCreated
For Each dw As DockWindow In CType(sender, RadDock).DockWindows
If dw.Handle <> CType(sender, RadDock).ActiveWindow.Handle AndAlso dw.DockState = DockState.AutoHide Then
dw.DockState = dw.PreviousDockState
RadDock1.AutoHideWindows(New DockWindow() {dw}, dw.Tag)
End If
Next
End Sub
Private Sub RadDock1_DockStateChanged(sender As Object, e As DockWindowEventArgs) Handles RadDock1.DockStateChanged
If e.DockWindow.DockState = DockState.Docked Then
e.DockWindow.Tag = GetDockPostition(e.DockWindow)
End If
End Sub
Public Function GetDockPostition(window As DockWindow) As AutoHidePosition
Dim type As Type = GetType(RadDock)
Dim mi As Reflection.MethodInfo = Me.RadDock1.[GetType]().GetMethod("GetAutoHidePosition", Reflection.BindingFlags.Instance Or Reflection.BindingFlags.NonPublic)
Dim res As Object = mi.Invoke(Me.RadDock1, New Object() {DirectCast(Me.RadDock1(window.Name).TabStrip, ToolTabStrip)})
Dim aHPposition As AutoHidePosition = DirectCast(res, AutoHidePosition)
Return aHPposition
End Function
