ListView的可编辑化

WPF经常用于显示数据报表，但是使用ListView只能完成显示作用，最近看到一帖子，上面详细讲述了怎么设置。我也尝试的做了一下：

具体操作就是把listview建立celltemplate，然后进行编辑，完成数据处理。

代码如下：

<DockPanel Grid.Row="1">
<ListView x:Name="listView" IsSynchronizedWithCurrentItem="True">
<ListView.Resources>

更改bool属性，满足wpf需要；
<local:BooleanToVisibilyBox x:Key="BooleanToVisibilyBox" />
<local:BooleanToVisibilyBlock x:Key="BooleanToVisibilyBlock" />

<Style x:Key="ListViewItemBlockStyle" TargetType="{x:Type TextBlock}">
<Setter Property="VerticalAlignment" Value="Center" />
<Setter Property="Width" Value="80" />

定义显示框内容：
<Setter Property="Visibility" Value="{Binding Path=IsSelected,
RelativeSource={RelativeSource FindAncestor,
AncestorType={x:Type ListViewItem}},
Converter={StaticResource BooleanToVisibilyBlock},
ConverterParameter=False }">
</Setter>
</Style>

定义编辑框内容：

<Style x:Key="ListViewItemBoxStyle" TargetType="{x:Type TextBox}">
<Setter Property="VerticalAlignment" Value="Center" />
<Setter Property="Width" Value="80" />
<Setter Property="Visibility" Value="{Binding Path=IsSelected,
RelativeSource={RelativeSource FindAncestor,
AncestorType={x:Type ListViewItem}},
Converter={StaticResource BooleanToVisibilyBox},
ConverterParameter=True}">
</Setter>
</Style>

</ListView.Resources>
<ListView.View>
<GridView AllowsColumnReorder="True">
<GridViewColumn Header="用户号码" Width="80" >
<GridViewColumn.CellTemplate>
<DataTemplate>
<Grid>
<TextBlock Style="{ StaticResource ListViewItemBlockStyle}" Text="{Binding Path=UserPrimaryID}" />
<TextBox Style="{StaticResource ListViewItemBoxStyle}" Text="{Binding Path=UserPrimaryID}" />
</Grid>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
<GridViewColumn Header="用户名" Width="80" >
<GridViewColumn.CellTemplate>
<DataTemplate>
<Grid>
<TextBlock Style="{ StaticResource ListViewItemBlockStyle}" Text="{Binding Path=UserName}" />
<TextBox Style="{StaticResource ListViewItemBoxStyle}" Text="{Binding Path=UserName}" />
</Grid>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
<GridViewColumn Header="用户密码" Width="80" DisplayMemberBinding="{Binding UserPwd}"/>
<GridViewColumn Width="80" Header="真实姓名">
<GridViewColumn.CellTemplate>
<DataTemplate>
<Grid>
<TextBlock Style="{StaticResource ListViewItemBlockStyle}" Text="{Binding Path=UserRealName}"></TextBlock>
<TextBox Style="{StaticResource ListViewItemBoxStyle}" Text="{Binding Path=UserRealName}"></TextBox>
</Grid>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
</GridView>
</ListView.View>
</ListView>
</DockPanel>

中途会涉及到BooleanVisibility的设置：代码如下：

public class BooleanToVisibilyBlock:IValueConverter
{
/// <summary>
/// 更改对象处理，将bool型数据转换为wpf可用的类型
/// </summary>
/// <param name="value">需要转换的值</param>
/// <param name="targetType">目标类型</param>
/// <param name="parameter">参数</param>
/// <param name="cultureinfo">设置格式</param>
/// <returns></returns>
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
    bool bBoolean = (bool)value;
    bool target = bool.Parse(parameter.ToString());
    if (bBoolean == true)
    {
        return Visibility.Hidden;
    }
    else
    {
        return Visibility.Visible;
    }
}

public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        Visibility visibility = (Visibility)value;
        if ( visibility == Visibility.Visible)
        {
        return true;
        }
        return false;
    }
}        

　　

有这两步配置，剩下的就是一些繁琐的数据登记了！

如果你在list中设置了button或者其它需要选择的单项，你在MVVM绑定的时候，绑定方式与单独的绑定不相同，需要设置如下：

　Command="{Binding ElementName=LVShowTable,Path=DataContext.UpdateCommand}"

　command="{Binding Path=UpdateCommand,Source={StaticResource XXXViewModel}}"
