infragistics - xamDockManager - ContentPane - height is not adjusting

Question

I am not able to set the height of my ContentPane inside a SplitPane. I am using Auto, but it is not able to set the height accordingly. I have 2 contentpanes in a splitpane. I need the two content panes relative in size. The heights should depend on the contents of the contentpanes. Any suggestions? Please look at my code:

         <igDock:XamDockManager Theme="Office2010Blue" Height="Auto">
            <igDock:XamDockManager.Panes>
                <igDock:SplitPane Name="dockedLeft" igDock:XamDockManager.InitialLocation="DockedLeft" Height="Auto">
                    <igDock:ContentPane x:Name="leftEdgeDock" Header="Reports">
                        <TreeView Width="Auto" DockPanel.Dock="Left" ItemsSource="{Binding Folders}" Height="Auto" Padding="0,0,20,20" MinWidth="100">
                            <TreeView.ItemContainerStyle>
                                <!-- 
                                    This Style binds a TreeViewItem to a TreeViewItemViewModel. 
                                    -->

                                <Style TargetType="{x:Type TreeViewItem}">
                                    <Setter Property="IsExpanded" Value="{Binding IsExpanded, Mode=TwoWay}" />
                                    <Setter Property="IsSelected" Value="{Binding IsSelected, Mode=TwoWay}" />
                                    <Setter Property="FontWeight" Value="Normal" />

                                    </Style.Triggers>
                                </Style>
                            </TreeView.ItemContainerStyle>

Answer 1

Our developers investigated this further and said that this behavior is expected since the SplitPane sizes and arranges the panes based on the ratio of the RelativeSize of each pane. The workaround here is to use different a different SplitPane for each ContentPane you want to use. Here is a simple XAML code snippet:

<igDock:XamDockManager >
    <igDock:XamDockManager.Panes>
        <igDock:SplitPane igDock:XamDockManager.InitialLocation="DockedTop" >
            <igDock:ContentPane x:Name="centerDock" />
        </igDock:SplitPane>
        <igDock:SplitPane igDock:XamDockManager.InitialLocation="DockedTop" >
            <igDock:ContentPane x:Name="bottomDock">
                <Button Content="Data To Excel" Height="23" Name="ExportToExcel" Width="110"  />
            </igDock:ContentPane>
        </igDock:SplitPane>
    </igDock:XamDockManager.Panes>
</igDock:XamDockManager>

Answer 2

I have been looking into this and I have logged this behavior with our developers in our tracking system. I can suggest you create an account in Infragistics community, if you doesn't have one:

http://www.infragistics.com/community/

and post your questions, related to Infragistics controls, there so you could get an answer from an Infragistics expert.

Also once there is any proggress on the issue I will update you.
