WPF:扩展ListView的GridView的最后一列

Question

我有一个带有3列GridView的ListView.我希望最后一列占用ListView的剩余宽度.

Answer 1

使用简单的XAML无法做到这一点,但有一些解决方案.看一下这个:

• ListView布局管理器
• ListView列的星号

Answer 2

有一种方法可以使用行为模式来实现

<ListView HorizontalAlignment="Stretch"
          Behaviours:GridViewColumnResize.Enabled="True">
        <ListViewItem></ListViewItem>
        <ListView.View>
            <GridView>
                <GridViewColumn  Header="Column *"
                                   Behaviours:GridViewColumnResize.Width="*" >
                    <GridViewColumn.CellTemplate>
                        <DataTemplate>
                            <TextBox HorizontalAlignment="Stretch" Text="Example1" />
                        </DataTemplate>
                    </GridViewColumn.CellTemplate>

Answer 3

快速而肮脏

XAML:

<ListView SizeChanged="ListView_SizeChanged" Loaded="ListView_Loaded" >
    <ListView.View>
        <GridView>
            <GridViewColumn Header="col1" Width="100" />
            <GridViewColumn Header="col1" Width="Auto" />
            <GridViewColumn Header="col1" />
        </GridView>
    </ListView.View>
</ListView>

CS:

private void ListView_SizeChanged(object sender, SizeChangedEventArgs e)
{
    UpdateColumnsWidth(sender as ListView);
}

private void ListView_Loaded(object sender, RoutedEventArgs e)
{
    UpdateColumnsWidth(sender as ListView);
}

private void UpdateColumnsWidth(ListView listView)
{
    int autoFillColumnIndex = (listView.View as GridView).Columns.Count - 1;
    if (listView.ActualWidth == Double.NaN)
        listView.Measure(new Size(Double.PositiveInfinity, Double.PositiveInfinity));
    double remainingSpace = listView.ActualWidth;
    for (int i = 0; i < (listView.View as GridView).Columns.Count; i++)
        if (i != autoFillColumnIndex)
            remainingSpace -= (listView.View as GridView).Columns[i].ActualWidth;
    (listView.View as GridView).Columns[autoFillColumnIndex].Width = remainingSpace >= 0 ? remainingSpace : 0;
}

如何使用样式

<Style x:Key="GridViewExtraStyle" TargetType="{x:Type GridViewColumnHeader}">
    <Setter Property="Background" Value="{x:Null}"/>
    <Setter Property="Foreground" Value="{x:Null}"/>
    <Setter Property="BorderBrush" Value="{x:Null}"/>
    <Setter Property="Width" Value="1000"/>
</Style>

<ListView>
    <ListView.View>
        <GridView>
            <GridViewColumn Header="Abc"/>
            <GridViewColumn Header="" HeaderContainerStyle="{DynamicResource GridViewExtraStyle}"/>
        </GridView>
    </ListView.View>
</ListView>
