Stretch empty WPF ListView to take the remaining space
I always have problems with a ListView inside a dynamic layout control like a Stackpanel.
Right now I have a Window with a Stackpanel as Root-Control. The Stackpanel streches perfectly and takes the complete window. Inside the StackPanel are some other controls like textboxes and button all aligned fine.
The last Object is a ListView. I want the ListView to take the remaining space from the StackPanel but it does not. Even with VerticalAlignment="Stretch" I only get the column headers. The ListView only grows when items are added to it. So I have to set the ListView height manually.
How can I make the ListView fill the remaining space in a StackPanel even when it is empty?
This has nothing to do with the ListView. It is the StackPanel's "fault". In a StackPanel the child items always consume only the space they need (in the direction of the orientation of the StackPanel). That's how the StackPanel is designed. Use a DockPanel instead, there you can make the last item fill up all the space that is left over using LastChildFill="true" ( true is default, so no need to explicity specify it).
<DockPanel Background="Green">
<Button DockPanel.Dock="Top">Text</Button>
<ListView DockPanel.Dock="Top">
<ListView.View>
<GridView>
<GridViewColumn/>
</GridView>
</ListView.View>
</ListView>
</DockPanel>
How about using a grid? Grids are made for this kind of layout. The DockPanel is a good suggestion too.
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<TextBlock Grid.Row="0" Text="row1"/>
<Button Grid.Row="1" Content="row2"/>
<ListView Grid.Row="2">
<ListViewItem Content="Text"/>
<ListViewItem Content="Text1"/>
<ListViewItem Content="Text2"/>
</ListView>
</Grid>
The important part is the Height="*", this tells the row to take up all available space, you can leave this out if you want as it is the default behaviour.
