WPF ListBox不同形式显示数据

一.每行显示固定列数

<ListBox ItemsSource="{Binding DataList}" Style="{DynamicResource ListBoxStyle}" ScrollViewer.HorizontalScrollBarVisibility="Disabled" >
	<ListBox.ItemsPanel>
	    <ItemsPanelTemplate>
	        <UniformGrid Columns="3"/>
	    </ItemsPanelTemplate>
	</ListBox.ItemsPanel>
	<ListBox.ItemTemplate>
	    <DataTemplate>
	        ...
	    </DataTemplate>
	</ListBox.ItemTemplate>
</ListBox>

二.每行显示列数随宽度变化

<ListBox ItemsSource="{Binding DataList}" Style="{DynamicResource ListBoxStyle}" ScrollViewer.HorizontalScrollBarVisibility="Disabled" >
	<ListBox.ItemsPanel>
	    <ItemsPanelTemplate>          
	        <WrapPanel IsItemsHost="True"/>
	    </ItemsPanelTemplate>
	</ListBox.ItemsPanel>
	<ListBox.ItemTemplate>
	    <DataTemplate>
	        ...
	    </DataTemplate>
	</ListBox.ItemTemplate>
</ListBox>

如果想更改他的排列顺序，比如将
1 2 3
4 5 6
7 8 9
改为
7 8 9
4 5 6
1 2 3
参考MSDN

public class UniformGridWithOrientation : UniformGrid

            DependencyProperty.Register("Orientation", typeof(System.Windows.Controls.Orientation), typeof(UniformGridWithOrientation),
                new FrameworkPropertyMetadata(
                    System.Windows.Controls.Orientation.Vertical,
                    FrameworkPropertyMetadataOptions.AffectsMeasure),
                new ValidateValueCallback(UniformGridWithOrientation.IsValidOrientation));

        internal static bool IsValidOrientation(object o)
        {

            if (orientation != System.Windows.Controls.Orientation.Horizontal)
            {

            return true;
        }

        {
            get { return (System.Windows.Controls.Orientation)GetValue(OrientationProperty); }
            set { SetValue(OrientationProperty, value); }
        }
        #endregion

        private int _columns;
        private int _rows;

然后调用

<ListBox ItemTemplate="{DynamicResource HoleListTemplate}" ItemsSource="{Binding PGHoles}">
     <ListBox.ItemsPanel>
         <ItemsPanelTemplate>
             <local:UniformGridWithOrientation Orientation="Horizontal" Columns="8" Rows="10"/>
         </ItemsPanelTemplate>
     </ListBox.ItemsPanel>
 </ListBox>
