我使用的ItemsControl DataTemplate中下。 我想用ID列进行排序ItemsControl的IC。
<DataTemplate x:Key="With">
<DockPanel>
<StackPanel DockPanel.Dock="Top" Orientation="Horizontal">
<TextBlock Text="{Binding Path=fil}" Style="{StaticResource Fixed}" Margin="0,0,6,8" />
<mui:ModernButton IconData="{StaticResource PlayIconData}" Click="FullPlayback" Margin="0,0,6,8" ></mui:ModernButton>
</StackPanel>
<StackPanel DockPanel.Dock="Left" Orientation="Horizontal">
<TextBlock Text="{Binding Path=e1}" Foreground="Red" Style="{StaticResource Fixed}" Margin="0,0,6,8" />
<TextBlock Text="{Binding Path=m1}" Foreground="LightSalmon" Style="{StaticResource Fixed}" Margin="0,0,6,8" />
<TextBlock Text="{Binding Path=n1}" Foreground="Orange" Style="{StaticResource Fixed}" Margin="0,0,6,8" />
<TextBlock Text="{Binding Path=m2}" Foreground="LightGreen" Style="{StaticResource Fixed}" Margin="0,0,6,8" />
<TextBlock Text="{Binding Path=m3}" Foreground="Green" Style="{StaticResource Fixed}" Margin="0,0,6,8" />
<TextBlock Text="{Binding ElementName=H1, Path=Items.Count,Mode=OneWay}" Style="{StaticResource Fixed}" Margin="0,0,6,8" />
</StackPanel>
<ItemsControl Name="ic" DockPanel.Dock="Bottom" ItemsSource="{Binding Path=seg}" ItemsPanel="{StaticResource HSPanel}">
<ControlTemplate TargetType="ItemsControl">
<Border>
<ScrollViewer VerticalScrollBarVisibility="Auto">
<ItemsPresenter />
</ScrollViewer>
</Border>
</ControlTemplate>
</ItemsControl.Template>
</ItemsControl>
</DockPanel>
</DataTemplate>
我想下面的选项,但排序不工作。
在用户控制装置的构造(后面代码)1.Tried排序像以下
ic.Items.SortDescriptions.Clear();
ic.Items.SortDescriptions.Add(new SortDescription("id", ListSortDirection.Ascending));
ic.Items.Refresh();
但我无法在代码中访问IC落后。 错误说“IC不会在目前情况下是否存在”
2.Tried CollectionViewSource下ItemsControl的XAML中它也不能正常工作。
<ItemsControl x:Name="ic" DockPanel.Dock="Bottom" ItemsSource="{Binding Path=segments}" ItemsPanel="{StaticResource HSPanel}">
<ItemsControl.Resources>
<CollectionViewSource x:Key="segments" Source="{Binding seg}">
<CollectionViewSource.SortDescriptions>
<scm:SortDescription PropertyName="id" Direction="Ascending"/>
</CollectionViewSource.SortDescriptions>
</CollectionViewSource>
</ItemsControl.Resources>
<ItemsControl.Template>
3.Tried CollectionViewSource控件模板下的XAML这也是行不通的。
<ControlTemplate TargetType="ItemsControl">
<ControlTemplate.Resources>
<CollectionViewSource x:Key="segments" Source="{Binding seg}" >
<CollectionViewSource.SortDescriptions>
<scm:SortDescription PropertyName="sortId" Direction="Ascending"/>
</CollectionViewSource.SortDescriptions>
</CollectionViewSource>
</ControlTemplate.Resources>
但我初始化的IC Loaded事件,并做从there.In排序这种情况下,首先在页面加载时,该项目不排序。 但是,当我移动到另一个用户控件,然后回来这个当前用户的控制,项目看起来完全整理出来。
private void ic_Loaded(object sender, RoutedEventArgs e)
{
ItemsControl ic = (ItemsControl)sender;
ic.Items.SortDescriptions.Clear();
ic.Items.SortDescriptions.Add(new SortDescription("id", ListSortDirection.Ascending));
ic.Items.Refresh();
}
