Question

I have a problem with layout

<ListBox Name="Tweets" Grid.Row="1" ItemsSource="{Binding Path=Tweets}" Background="#1F0000FE">
        <ListBox.ItemTemplate>
            <DataTemplate>
                <local:TweetTemplate Margin="10"/>
            </DataTemplate>
        </ListBox.ItemTemplate>
    </ListBox>

Here is my template:

<Grid Name="grid">
    <Grid.RowDefinitions>
        <RowDefinition Height="25*" />
        <RowDefinition Height="95*" />
    </Grid.RowDefinitions>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="110" />
        <ColumnDefinition Width="*" />
    </Grid.ColumnDefinitions>
    <Image Source="{Binding Path=FromImage}" Grid.RowSpan="2" Margin="7" />
    <TextBlock Text="{Binding Path=From}" Margin="5" Grid.Column="1" />
    <TextBlock Text="{Binding Path=Text}" TextWrapping="WrapWithOverflow" Grid.Row="1" Margin="7" Grid.Column="1" />
</Grid>

My problem is when this <TextBlock Text="{Binding Path=Text}" text is very long, it stretches the Grid. And then stretches Parent controls. I want that text don’t stretch Listbox, and when it reaches the end of the ListBox width, switched to a new line. And when the window is resized, the size of ListBox should be increased. It means to use all of the window.

ListBox creates ScrollViewer for displaying items, so you should manually disable it with ScrollViewer.HorizontalScrollBarVisibility property:

    <ListBox Name="Tweets" 
             Grid.Row="1" 
             ItemsSource="{Binding Path=Tweets}" 
             Background="#1F0000FE"
             ScrollViewer.HorizontalScrollBarVisibility="Disabled">
        ...
    </ListBox>
