TextBlock TextWrapping不包装#2

Question

好的...所以这个解决方案没有帮助

XAML就在这里

  <ListBox  ItemsSource="{Binding Path=ContentItems}" Background="White" >
                <ListBox.ItemTemplate>
                    <DataTemplate>
                        <Grid Margin="2" Height="Auto" Width="Auto">
                            <Grid.ColumnDefinitions>
                                <ColumnDefinition Width="Auto" />
                                <ColumnDefinition Width="*" />
                            </Grid.ColumnDefinitions>
                            <Grid Grid.Column="0">
                                <Grid.RowDefinitions>
                                    <RowDefinition Height="Auto"/>
                                    <RowDefinition Height="Auto"/>
                                </Grid.RowDefinitions>
                                <StackPanel Grid.Row="0" Orientation="Horizontal">
                                    <Label VerticalAlignment="Center"  Margin="0,0,0,5">Start</Label><svl:TimeEditor Value="{Binding Path=FormatedStart}" Width="87"  HorizontalAlignment="Left"  Margin="2,8"  Name="dtpStart" FontSize="12"  Height="25"  VerticalAlignment="Center"     />
                                    <Label VerticalAlignment="Center"  Margin="0,0,0,5">End</Label><svl:TimeEditor Value="{Binding Path=FormatedEnd}" Width="87"  HorizontalAlignment="Left"  Margin="2,8"  Name="dtpEnd" FontSize="12"  Height="25"  VerticalAlignment="Center"     />
                                </StackPanel>                               
                                <TextBlock Grid.Row="1"  TextWrapping="Wrap"  Name="tbText" Text="{Binding Path=Data}"></TextBlock>
                            </Grid>
                            <Grid Grid.Column="1" Visibility="Collapsed">
                            </Grid>
                        </Grid>
                    </DataTemplate>
                </ListBox.ItemTemplate>
            </ListBox>

Answer 1

The following will helps for text wrapping:

<ListBox ScrollViewer.HorizontalScrollBarVisibility="Disabled">

Answer 2

嗯,你TextBlock不需要因为你的指定包装Width作为Auto它的ColumnDefinition允许它把所有的Width需要,即使在四溢的成本,以适应内容.您需要将Column的宽度设置为"*"以允许TextWrapping在请求的宽度超出允许值时启动,或者MaxWidth使用Binding 手动强制打开它

<TextBlock Name="tbText" Grid.Row="1" MaxWidth="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ListBox}}, Path=ActualWidth}" Text="{Binding Path=Data}" TextWrapping="Wrap" />
