Question

我有一个CheckedListBox控件是通过将DataTemplate与CheckBox添加到ListView而创建的。问题是我也需要列。

以下代码不显示复选框：

<ListView x:Name="lbDatabases" Height="138" Width="498" Canvas.Left="44" Canvas.Top="146">
    <ListView.View>
        <GridView>
            <GridViewColumn DisplayMemberBinding="{Binding DbName}" Header="Databases" Width="498"/>
        </GridView>
    </ListView.View>
    <ListView.ItemTemplate>
        <DataTemplate>                    
            <CheckBox IsChecked="{Binding IsActive}" Checked="AnyChange" Unchecked="AnyChange"  Style="{x:Null}" Content="{Binding DbName}"
                      Width="{Binding CheckWidth}" />
        </DataTemplate>
    </ListView.ItemTemplate>
</ListView>

但是，如果我注释掉这段代码，一切正常但没有列：

<ListView.View>
    <GridView >
        <GridViewColumn DisplayMemberBinding="{Binding DbName}" Header="Databases" Width="498"/>
    </GridView>
</ListView.View>

有没有办法拥有一切？

您需要将数据模板定义为列的CellTemplate：

<ListView x:Name="lbDatabases" Height="138" Width="498" Canvas.Left="44" Canvas.Top="146"  >
    <ListView.View >
        <GridView >
            <GridViewColumn Header="Databases" Width="498">
                <GridViewColumn.CellTemplate>
                    <DataTemplate>
                        <CheckBox IsChecked="{Binding IsActive}" Checked="AnyChange" Unchecked="AnyChange"  Style="{x:Null}" Content="{Binding DbName}"
                                  Width="{Binding CheckWidth}" />
                    </DataTemplate>
                </GridViewColumn.CellTemplate>
            </GridViewColumn>
        </GridView>
    </ListView.View>
</ListView>

在整个上午挣扎之后我都明白了。它们的关键是使用CellTemplate：

 <ListView x:Name="lbDatabases" Height="138" Width="498" Canvas.Left="44" Canvas.Top="146"  Style="{StaticResource ListViewStyle}">
        <ListView.View >
            <GridView>
                <GridViewColumn Header="Databases" Width="498">
                    <GridViewColumn.CellTemplate>
                        <DataTemplate>
                        <CheckBox IsChecked="{Binding IsActive}" Checked="AnyChange" Unchecked="AnyChange"  Style="{x:Null}" Content="{Binding DbName}"
                   Width="{Binding CheckWidth}" />
                        </DataTemplate>
                    </GridViewColumn.CellTemplate>
                </GridViewColumn>
            </GridView>
        </ListView.View>            
    </ListView>
