WPF window status bar disappears when window is sized smaller

Question

I've been playing around with c# and WPF for about 3 weeks now trying to create a plugin to get things done faster in Revit. I've solved most problems by myself, but this one I could really do with some help. So I have this WPF window that will have a few tabs, one to select things, others to set settings and print, etc. The default window size works for my example file, but when I resize it, the DataGrid does not resize with the table, and If I make the window smaller the status bar will disappear. Also, the DataGrid could do with scrollbars.

                    <DataGrid Name="uiViewDisplay" Grid.Row="1" SelectionUnit="FullRow" SelectionMode="Extended"  Loaded="OnGridLoad">

                                <DataGridTemplateColumn.CellTemplate>
                                    <DataTemplate>
                                        <CheckBox IsChecked="{Binding IsSelected, RelativeSource={RelativeSource AncestorType=DataGridRow}, Mode=TwoWay}" IsHitTestVisible="False"/>
                                    </DataTemplate>
                                </DataGridTemplateColumn.CellTemplate>
                            </DataGridTemplateColumn>
                        </DataGrid.Columns>
                    </DataGrid>
                </Grid>
            </TabItem>
            <TabItem Header="Print Settings" Margin="-2,0,-2,-2">
            </TabItem>
        </TabControl>
        <StatusBar DockPanel.Dock="Bottom" Height="20" VerticalAlignment="Bottom">
            <StatusBar.ItemsPanel>
                <ItemsPanelTemplate>
                    <Grid>
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition Width="100" />
                            <ColumnDefinition Width="Auto"/>
                            <ColumnDefinition Width="100" />
                            <ColumnDefinition Width="Auto"/>
                            <ColumnDefinition Width="*" />
                        </Grid.ColumnDefinitions>
                    </Grid>
                </ItemsPanelTemplate>
            </StatusBar.ItemsPanel>
            <StatusBarItem Grid.Column="0">
                <TextBlock>Sheets Selected</TextBlock>
            </StatusBarItem>
            <Separator Grid.Column="1"/>
            <StatusBarItem Grid.Column="2">
                <TextBlock>Views Selected</TextBlock>
            </StatusBarItem>
            <Separator Grid.Column="3"/>
            <StatusBarItem Grid.Column="4">
                <ProgressBar Value="70" Width="90" Height="20"/>
            </StatusBarItem>
        </StatusBar>
    </DockPanel>
</Window>

This is like the default opening position, which is almost perfect

And when I shrink the window, status bar has disappeared - and the data grid could do with scroll bars.

Thanks for any suggestions.

<Grid>
   <Grid.RowDefinitions>
       <RowDefinition Height="*"/>
       <RowDefinition Height="Auto"/>
   <Grid.RowDefinitions>

   <DataGrid Grid.Row="0"/>
   <StatusBar Grid.Row="1"/>

<Grid>

Use a Grid instead of a DockPanel. Then, define the Grid.Row attached property to your DataGrid and StatusBar accordingly.

If you need a powerful table that can display complex data, or support complex data operations, I suggest looking at the Data Grid made by DevExpress.
