WPF ListView with GridViewColumn and DataTemplate
提问by Ready Cent
I have a CheckedListBoxcontrol which is created by adding a DataTemplatewith a CheckBoxto a ListView. The problem is that I need columns too.
我有一个CheckedListBox控件，它是通过将 a 添加到DataTemplateaCheckBox来创建的ListView。问题是我也需要列。
The following code doesn't display the check boxes:
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>
However, if I comment out this code, everything works fine but no columns:
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>
Is there any way to have it all?
有什么办法可以拥有这一切吗？

You need to define the data template as CellTemplate for your column:
您需要为您的列定义数据模板为 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>

ok after struggling all morning I figured it out. They key here is to use a CellTemplate:
好吧，经过一上午的努力，我想通了。这里的关键是使用 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>
