通过一些创造性的使用ListView，你可以达到预期的效果。您可能还需要调整一些ListView模板以避免某些ListView特定的行为。

<ListView ScrollViewer.CanContentScroll="False"> 
     <ListView.View> 
      <GridView> 
       <GridViewColumn> 
        <GridViewColumn.HeaderTemplate> 
         <DataTemplate> 
          <!-- Header/Frozen content goes here --> 
          <!-- Using Border as example --> 
          <Border Width="1000" Height="40"> 
           <Border.Background> 
            <LinearGradientBrush> 
             <GradientStop Offset="0" Color="Lime"/> 
             <GradientStop Offset="1" Color="Black"/> 
            </LinearGradientBrush> 
           </Border.Background> 
          </Border> 
         </DataTemplate> 
        </GridViewColumn.HeaderTemplate> 
       </GridViewColumn> 
      </GridView> 
     </ListView.View> 
     <ListViewItem> 
      <ListViewItem.Style> 
       <Style TargetType="{x:Type ListViewItem}"> 
        <Setter Property="Template"> 
         <Setter.Value> 
          <ControlTemplate> 
           <!-- Other content goes here --> 
           <!-- Using Border as example --> 
           <Border Width="1000" Height="1000"> 
            <Border.Background> 
             <LinearGradientBrush> 
              <GradientStop Offset="0" Color="White"/> 
              <GradientStop Offset="1" Color="Black"/> 
             </LinearGradientBrush> 
            </Border.Background> 
           </Border> 
          </ControlTemplate> 
         </Setter.Value> 
        </Setter> 
       </Style> 
      </ListViewItem.Style> 
     </ListViewItem> 
    </ListView>
