XAML Columndefinitions width * not taking available space

问题

I know how the columndefinition works in XAML but there is something I want to do and don't know how.

I want 4 columns like that:

<Grid.ColumnDefinitions>
    <ColumnDefinition Width="110" />
    <ColumnDefinition Width="*" />
    <ColumnDefinition Width="80" />
    <ColumnDefinition Width="80" />
</Grid.ColumnDefinitions>

column has fixed width
column must take all the available space (yes it is between columns and this is exactly the problem)
column has fixed width
column has fixed width

The 2nd column contains text and the problem is that when that text is too short the 2nd column does not take all the available space. it get's smaller automatically and this for each row. I can make it work with this code in the textblock:

MinWidth="2000"

But it's not the good way since this number could be too low when the screen is big.

Here the whole listview containing the 4 columns:

<ListView Grid.Row="1" Grid.ColumnSpan="4" ItemsSource="{Binding blabla}" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch">
    <ListView.ItemTemplate>
        <DataTemplate>
            <Grid>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="110" />
                    <ColumnDefinition Width="*" />
                    <ColumnDefinition Width="80" />
                    <ColumnDefinition Width="80" />
                 </Grid.ColumnDefinitions>
                <Image Height="110" Width="110" Grid.Column="0" Source="{Binding blabla}" HorizontalAlignment="Stretch" />
                <TextBlock Text="{Binding blabla}" TextWrapping="Wrap" Margin="5,0,0,0" Grid.Column="1" FontSize="16" HorizontalAlignment="Stretch" TextAlignment="Left" FlowDirection="LeftToRight" MinWidth="2000" VerticalAlignment="Center" ScrollViewer.HorizontalScrollBarVisibility="Disabled" FontStretch="UltraCondensed"/>
                <TextBlock Grid.Column="2" TextWrapping="Wrap" Foreground="Black" Margin="5,0,0,0" HorizontalAlignment="Stretch" VerticalAlignment="Center"/>
                <Image Source="{Binding blabla, Converter={StaticResource ImgConverter}}" Grid.Column="3" Width="76" Height="76" HorizontalAlignment="Center" Stretch="None" VerticalAlignment="Center" Margin="0"/>
            </Grid>
        </DataTemplate>
    </ListView.ItemTemplate>
</ListView>

回答1:

Your layout is well-defined but missed a small thing that is causing that the content of the Listviewitem is margined to the left because that is defined in the default ListViewItemStyle which is named "ItemContainerStyle" for the ListView Control .

All what you need to do is add this ListViewItemStyle that I've modified to stretch the content Horizontally and Vertically across all the available space for the item to your Resources

<Style x:Key="StretchedListViewItemStyle"
           TargetType="ListViewItem">
         <Setter Property="HorizontalContentAlignment"
                Value="Stretch" />
        <Setter Property="VerticalContentAlignment"
                Value="Stretch" />
</Style>

Then set it as the ItemContainerStyle for the ListView as follows:

<ListView Grid.Row="1" Grid.ColumnSpan="4" ItemsSource="{Binding blabla}" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch" ItemContainerStyle="{StaticResource StretchedListViewItemStyle}"/>
