Question

WPF中，ListView中数据显示的问题，部分代码如下：

在<window.Resources>中定义的
<GridView x:Key="GridView"> <GridViewColumn Width="150" Header="称" CellTemplate="{StaticResource DisplayImage}">
</GridViewColumn>
<GridViewColumn DisplayMemberBinding="{Binding DateTime}" Width="160" Header="修改时间">
</GridViewColumn>
<GridViewColumn DisplayMemberBinding="{Binding Type}" Width="90" Header="类型">
</GridViewColumn> <GridViewColumn DisplayMemberBinding="{Binding Size}" Width="110" Header="大小">
</GridViewColumn>
</GridView>

<DataTemplate x:Key="bigImage">
<DockPanel Height="33" Width="150">
<Image Source="{Binding Image}" Margin="2"></Image>
<TextBlock DockPanel.Dock="Top" Text="{Binding Name}" FontSize="13" HorizontalAlignment="Left" Margin="0,0,0,1" />
<TextBlock Text="{Binding Type}" FontSize="9" HorizontalAlignment="Left" Margin="0,0,0,1" />
</DockPanel>
</DataTemplate>
<loc:PlainView x:Key="ImageView" ItemTemplate="{StaticResource bigImage}" ItemWidth="100" ></loc:PlainView> 其中PlainView是自定义的类，继承自ViewBase，该类的代码如下：
class PlainView : ViewBase {
public PlainView()
{

} public static readonly DependencyProperty
ItemContainerStyleProperty =
ItemsControl.ItemContainerStyleProperty.AddOwner(typeof(PlainView));
public static readonly DependencyProperty ItemTemplateProperty = ItemsControl.ItemTemplateProperty.AddOwner(typeof(PlainView)); public DataTemplate ItemTemplate {
get { return (DataTemplate)GetValue(ItemTemplateProperty); }
set { SetValue(ItemTemplateProperty, value); }
}
public static readonly DependencyProperty ItemWidthProperty = WrapPanel.ItemWidthProperty.AddOwner(typeof(PlainView));
public double ItemWidth {
get { return (double)GetValue(ItemWidthProperty); }
set { SetValue(ItemWidthProperty, value); }
}
public static readonly DependencyProperty ItemHeightProperty =
WrapPanel.ItemHeightProperty.AddOwner(typeof(PlainView));

public double ItemHeight {
get { return (double)GetValue(ItemHeightProperty); }
set { SetValue(ItemHeightProperty, value); }
}
}
事件处理的部分代码是：
if (str == "GridView")
{
fileBox.View = fileBox.FindResource("GridView") as ViewBase;
}
else if (str == "ImageView")
{
fileBox.View = fileBox.FindResource("ImageView") as ViewBase;
}
运行后，资源GridView好用，但是ImageView不好用，显示的都是默认的数据。

你是说ImageView使用资源bigImage看不到效果？

追问

是的,看不到效果,没有引用到这个模板.

追答

那会不会是listview.view只能用GridView呢？
