Q309 Prerelease build 1419 references components in unavailable build 1418

Just downloaded build 1419 from the website. The Telerik.Windows.Controls.Docking.dll references build 1418 which is not publicly available. Anyone know a workaround for this until we get another prerelease from Telerik?

Memory leak?

Hello,
In my application I add a usercontrol containing raddocking to the visual tree. When I remove this usercontrol from the visual tree it stays in memory because it seems that raddocking still has a reference to something. See example code below.

    
            <UserControl xmlns:my="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Docking"  x:Class="UserControl1" 
        
                         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
        
                         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

                        <my:RadDocking></my:RadDocking> 
        
                </Grid> 
        
            </UserControl>

    
            <Window x:Class="MainWindow"

                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

                </Grid> 
        
            </Window>

RadSplitContainer.ChildrenOfType

hi,

i have this sample code:

                    RadPane FormRadPane = new RadPane() { Header = "Not Document Pane", CanDockInDocumentHost = false };         
            TextBlock txtBlock = new TextBlock();         
            txtBlock.Text = "This Pane Cannot be docked in to document host";         
            FormRadPane.Content = txtBlock;         
                     
            RadPaneGroup NewPaneGroup = new RadPaneGroup();         
            NewPaneGroup.Items.Add(FormRadPane);         
                     
            RadSplitContainer FormSplitContainer = new RadSplitContainer();         
            FormSplitContainer.InitialPosition = DockState.FloatingDockable;         
            FormSplitContainer.Items.Add(NewPaneGroup);         
                     
            MainDockingControl.Items.Add(FormSplitContainer);         

i've put a breakpoint on the last code row.

in the immediate window in run time i write:

                    FormSplitContainer.ChildrenOfType<RadPane>()         

and it i get no items i.e. "Items Count = 0".

meaning - the split container doesn't contain any panes.

is that a bug?

DocumentHost with no panes

hi,
i have a simple DockControl XAML:

    
            <radDock:RadDocking FlowDirection="RightToLeft" DockPanel.Dock="Bottom"> 
        
                            <radDock:RadDocking.DocumentHost> 
        
                                <radDock:RadPaneGroup> 
        
                                    <radDock:RadPane Header="Bottom Docked Control - Pane #1" CanFloat="true"> 
        
                                        <TextBlock>Bottom Docked Control - Pane #1</TextBlock> 
        
                                    </radDock:RadPane> 
        
                                    <radDock:RadPane Header="Bottom Docked Control - Pane #2" CanFloat="true"> 
        
                                        <TextBlock>Bottom Docked Control - Pane #2</TextBlock> 
        
                                    </radDock:RadPane> 
        
                                    <radDock:RadPane Header="Bottom Docked Control - Pane #3" CanFloat="true"> 
        
                                        <TextBlock>Bottom Docked Control - Pane #3</TextBlock> 
        
                                    </radDock:RadPane> 
        
                                </radDock:RadPaneGroup> 
        
                            </radDock:RadDocking.DocumentHost> 
        
                        </radDock:RadDocking>

what happens is when i float (undock) all of the panes from the DocumentHost i can't dock them again in the DocumentHost
only dock them to four sides, the compass doesn't give me the option, it's like the DocumentHost Disappear when it has no Panes
docking inside it, is there a solution to this situation or do i have to make sure that a least on pane will stay in the DocumentHost
so i can dock to it?

thank so much in advance.

Scrollbar inconsistency & filter problem

I am running 2009.3.1322.35. I have a RadGridView in a StackPanel in a Popup. My problem is that the first time the popup appears the horizontal scrollbar for the RadGridView is either not visible or is visible but does not allow one to scroll and see all of the text. The scrollbar works properly the second time the popup is visible.

<Popup IsOpen="{Binding Path=ValidSoftwareIsOpen, Mode=OneWay}"

AllowsTransparency="True"

PopupAnimation="Slide"

Placement="Center"

Width="Auto"

Height="Auto"

PlacementTarget="{Binding ElementName=avionicsviewBorder }"

Name="validSoftware"

StaysOpen="True"

>

<Border BorderThickness="5" BorderBrush="Black" Opacity="1" Width="Auto"

Height="Auto" CornerRadius="5,5,5,5">

Valid Software

</Label>

</Border>

<telerik:RadGridView

Name="ValidSoftwareListView"

ItemsSource="{Binding Path=AircraftSoftwareValidCollection}"

CanUserInsertRows="False"

SnapsToDevicePixels="True"

HeaderRowStyle="{DynamicResource radGridViewHeaderStyle}"

AutoGenerateColumns="False"

IsReadOnly="True"

Width="300"

ColumnsWidthMode="Auto"

telerik:StyleManager.Theme="Office_Black"

FontSize="12"

>

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn Header="Name" UniqueName="SoftwareName" DataMemberBinding="{Binding Path=Name}" Width="Auto"/>

<telerik:GridViewDataColumn Header="CSCI" UniqueName="SoftwareCsci" DataMemberBinding="{Binding Path=Csci}" Width="Auto"/>

<telerik:GridViewDataColumn Header="Current" UniqueName="SoftwareCurrent" DataMemberBinding="{Binding Path=Current}" Width="Auto"/>

<telerik:GridViewDataColumn Header="Replacement" UniqueName="SoftwareReplacement" DataMemberBinding="{Binding Path=Replacement}" Width="Auto"/>

</telerik:RadGridView.Columns>

</telerik:RadGridView>

<Button Template="{DynamicResource GlassButton}" Content="Ok" HorizontalAlignment="Right"

VerticalAlignment="Center"

Command="{Binding Path=OkCommand}" Style="{DynamicResource bottomButtonStyle}"/>

</StackPanel>

</Border>

</Popup>

I tried replacing the StackPanel with a grid with no sucess.

Another issue I have is that if my application window is full screen and I have my popup centered in the window and I click on a filter the filter popup does not show all the fields. This is not a problem when the application window is not full screen.
