Differnce b/w Programatically moving the toolwindow to Docksite and Mannually Drag and Move to Base.

Hi,

What is the Differnce b/w Programatically moving the toolwindow to Docksite and Mannually Drag and Move to Base ?

Programatically docking to BaseDocksite and resizing it not calling the SizeChange of the View in that toolwindow......

Sample application-----

<Docking:Docksite x:Name="BaseDocksite">

<Docking:Workspace>

<Grid.RowDefinitions>

<RowDefinition Height="Auto"/>

<RowDefinition Height="*"/>

</Grid.RowDefinitions>

<Docking:Docksite x:Name="Docksite1" Grid.Row="0">

</Docking:Doxcksite>

<Docking:Docksite x:Name="Docksite2 Grid.Row="1">

</Docking:Doxcksite>

</Docking:Workspace>

</Docking:Docksite>

I have two usercontrols named UserControl1 and UserControl2.

I am loading the these Usercontrols as the Toolwindow using the PrismIntegration with Docking.

with the help  this.regionManager.Regions[Constants.Docksite1].Add(Docksite1ViewModel);

Scenario1--->

This view model consists of Initialize and   Open mathod of Docking Window Interface.

In Open Method i use like toolwindow.Dock(Docksite1.Direction.Left);

Same for Usercontrol2.

As i run the application Usercontrol1 and Usercontrol2 are displayed as the Toolwindow .

As Docksite1 and Docksite2 are linked with the BaseDocksite.

i Drags the Usercontrol1Toolwindow to BaseDocksite and i resize the UserControl1Toolwindow then its also resizing the Content of UserControl1.

Scenario2--->

This view model consists of Initialize and Open mathod of Docking Window Interface.

As Docksite1 and Docksite2 are linked with the BaseDocksite.

In Open Method i use like toolwindow.Dock(BaseDocksite.Direction.Left);

Same for Usercontrol2.

As i run the application Usercontrol1 and Usercontrol2 are displayed as the Toolwindow .

I resize the UserControl1Toolwindow then its Resizing  is not calling the resizing of UserControl1.

I need to implement the Scenario2(Programatically docking the toolwindow to the BaseDocksite) but its not resizing the Content of the View.

So for that What should i do....?
