WPF ListView的虚拟化。如何禁用的ListView虚拟化？ [英] WPF ListView virtualization. How to disable ListView virtualization?

问题描述

我有一些麻烦与自定义的ListView（复选框滚动的ListView里面的时候失去了他们的状态）。我可以禁用虚拟化的ListView没有视觉树枚举？

 ＆LT; ListView控件＆GT;
    ＆LT; ListView.Resources＆GT;
        ＆LT;风格的TargetType =GridViewColumnHeader＆GT;
            ＆LT; setter属性=能见度VALUE =折叠/＆GT;
        ＆LT; /样式和GT;
    ＆LT; /ListView.Resources>
    ＆LT; ListView.View＆GT;
        ＆LT; GridView控件＆GT;
            ＆LT; GridViewColumn标题=地址＆GT;
                ＆LT; GridViewColumn.CellTemplate＆GT;
                    ＆LT;的DataTemplate＆GT;
                        ＆LT;复选框CONTENT ={绑定地址}/＆GT;
                    ＆LT; / DataTemplate中＆GT;
                ＆LT; /GridViewColumn.CellTemplate>
            ＆LT; / GridViewColumn＆GT;
            ＆LT; GridViewColumn标题=名称＆GT;
                ＆LT; GridViewColumn.CellTemplate＆GT;
                    ＆LT;的DataTemplate＆GT;
                        ＆LT; TextBlock的文本={结合名}/＆GT;
                    ＆LT; / DataTemplate中＆GT;
                ＆LT; /GridViewColumn.CellTemplate>
            ＆LT; / GridViewColumn＆GT;
        ＆LT; / GridView的＆GT;
    ＆LT; /ListView.View>
＆LT; / ListView控件＆GT;
 

解决方案

正如由HB在<一个href="http://stackoverflow.com/questions/13326506/listbox-is-virtual-by-default/13330630#13330630">their回答这里：

  

套装   <一href="http://msdn.microsoft.com/en-us/library/system.windows.controls.virtualizingstackpanel.isvirtualizing.aspx"相对=nofollow> VirtualizingStackPanel.IsVirtualizing   假的的ListView 或设置正常    的StackPanel   作为    ListView.ItemsPanel 。

 ＆LT; ListView控件VirtualizingStackPanel.IsVirtualizing =FALSE/＆GT;
 

或

 ＆LT; ListView控件＆GT;
 ＆LT; ListView.ItemsPanel＆GT;
     ＆LT; ItemsPanelTemplate＆GT;
       ＆LT; StackPanel的＆GT;＆LT; / StackPanel的＆GT;
      ＆LT; / ItemsPanelTemplate＆GT;
  ＆LT; /ListView.ItemsPanel>
 ＆LT; / ListView控件＆GT;
 

I have some troubles with custom ListView (CheckBoxes inside lost their states when scrolling ListView). Can I disable ListView virtualization without visual tree enumerating?

<ListView>
    <ListView.Resources>
        <Style TargetType="GridViewColumnHeader">
            <Setter Property="Visibility" Value="Collapsed" />
        </Style>
    </ListView.Resources>
    <ListView.View>
        <GridView>
            <GridViewColumn Header="Address">
                <GridViewColumn.CellTemplate>
                    <DataTemplate>
                        <CheckBox Content="{Binding Address}"/>
                    </DataTemplate>
                </GridViewColumn.CellTemplate>
            </GridViewColumn>
            <GridViewColumn Header="Name">
                <GridViewColumn.CellTemplate>
                    <DataTemplate>
                        <TextBlock Text="{Binding Name}"/>
                    </DataTemplate>
                </GridViewColumn.CellTemplate>
            </GridViewColumn>
        </GridView>
    </ListView.View>
</ListView>

解决方案

As stated by H.B. in their answer here:

Set VirtualizingStackPanel.IsVirtualizing to false on the ListView or set a normal StackPanel as the ListView.ItemsPanel.

<ListView VirtualizingStackPanel.IsVirtualizing="False"/>

or

<ListView>
 <ListView.ItemsPanel>
     <ItemsPanelTemplate>
       <StackPanel></StackPanel>
      </ItemsPanelTemplate>
  </ListView.ItemsPanel>
 </ListView>
