从ListView

Question

我正在构建一个UWP应用程序，我的ListView有问题。我想从ListView中的TextBlock更改ColumnSpan。

                    <ListView Grid.Row="1" BorderBrush="#0062AD" BorderThickness="1" ItemsSource="{Binding BusRoutes}" x:Name="Routes1" SelectionMode="None"   IsItemClickEnabled="False"  Padding="0 10 0 0">

                    <ListView.ItemTemplate>
                        <DataTemplate>
                            <Grid Width="400">
                                <Grid.ColumnDefinitions>
                                    <ColumnDefinition Width="*"/>
                                    <ColumnDefinition Width="*"/>
                                </Grid.ColumnDefinitions>
                                <Grid.RowDefinitions>
                                    <RowDefinition Height="*"/>
                                </Grid.RowDefinitions>
                                <TextBlock x:Name="startingPoint" Grid.Row="0" Grid.Column="0"  Padding="0 10 0 10" TextAlignment="Center" HorizontalAlignment="Center" Text="{Binding hours}"/>
                                <TextBlock TextAlignment="Center"  Grid.Row="0" Grid.Column="1"  Padding="0 10 0 10" x:Name="endingPoint" HorizontalAlignment="Center" Text="{Binding hours2}" />
                            </Grid>
                        </DataTemplate>
                    </ListView.ItemTemplate>
                </ListView>

我的意思是我想设置名为startingPoint ColumnSpan = 2的TextBlox并以编程方式将名称为endsPoint的TextBlock设置为Collapsed。这可能吗？

Answer 1

是的，您可以使用以下命令更改列范围并以编程方式设置可见性：

endingPoint.Visibility = Visibility.Collapsed; //to make it invisible
Grid.SetColumnSpan(startingPoint, 2); //to change it the 2 column span

希望它有所帮助。
