New Post: Avalon dock side default Dock side width

Hallo ,

Im new in WPF Toolkit. im trying to implement layout of my application with Avallon dock. Most works fine, but i've paar small problems. I realized some menues as shown here

<xcad:LayoutRoot.BottomSide >
                    <xcad:LayoutAnchorSide x:Name="BottomSide" >
                        
                        <xcad:LayoutAnchorGroup  >
                            <xcad:LayoutAnchorable   AutoHideHeight="300"
                                                     FloatingHeight="300"
                                                     CanFloat="False"
                                                     CanClose="False"
                                                     
                                                     CanHide="False" 
                                                     Title="MyTitel"
                                                     IconSource="StaticResource HeaderIcon}" >
                                <rate:MyUserControl
                                                           Padding="3"/>
                            </xcad:LayoutAnchorable>
....

Is it posible to set set Default width for a Docking side?
If I set one of thet Panels as Docked it lost it focus.(The first Panel is then selected ). Is it Possible thet the panel stays in focus(or some work around).
