GridView控件需要太多的CPU在WPF

Question

我有這樣的GridView的定義在我的WPF應用程序，還我使用ComponentArt

<my1:GridView Name="gridView1" Theme="ArcticWhite" Indent="40" RowClicked="gridView1_RowClicked_1" AllowColumnFreezing="False" AllowRowFreezing="False" ColumnResizingMode="Normal" AllowColumnReordering="False" AutoGenerateColumns="False" IsHitTestVisible="True" ThemeVariant="Standard" Foreground="#FFDBDBCD"> 
    <my1:GridView.Columns> 
     <my1:GridViewTemplateColumn Binding="{Binding}" Header="Local"> 
      <my1:GridViewTemplateColumn.CellTemplate> 
       <DataTemplate> 
        <Grid Margin="-7,-3,-2,-3" Name="grid1"> 
         <Grid.Background> 
          <MultiBinding Converter="{StaticResource BackgroundBrushConverter}"> 
           <Binding ElementName="r1" Path="Fill"></Binding> 
           <Binding ElementName="cbColores" Path="IsChecked"></Binding> 
          </MultiBinding> 
         </Grid.Background> 
         <Rectangle Name="r1" Fill="{Binding Converter={StaticResource BrushConverter}}" Width="1" Height="1"></Rectangle> 
         <TextBlock Margin="3" Foreground="Black" Text="{Binding Local}" FontFamily="Calibri" FontWeight="Bold" FontSize="13"> 
        <TextBlock.Effect> 
         <DropShadowEffect Color="White" BlurRadius="3" ShadowDepth="0" Opacity="5" /> 
        </TextBlock.Effect> 
         </TextBlock> 
        </Grid> 
       </DataTemplate> 
      </my1:GridViewTemplateColumn.CellTemplate> 
     </my1:GridViewTemplateColumn> 
     <my1:GridViewTemplateColumn Binding="{Binding}" Header="Linea"> 
      <my1:GridViewTemplateColumn.CellTemplate> 
       <DataTemplate> 
        <Grid Margin="-7,-3,-2,-3" Name="grid2"> 
         <Grid.Background> 
          <MultiBinding Converter="{StaticResource BackgroundBrushConverter}"> 
           <Binding ElementName="r2" Path="Fill"></Binding> 
           <Binding ElementName="cbColores" Path="IsChecked"></Binding> 
          </MultiBinding> 
         </Grid.Background> 
         <Rectangle Name="r2" Fill="{Binding Converter={StaticResource BrushConverter}}" Width="1" Height="1"></Rectangle> 
         <TextBlock Margin="3" Foreground="Black" Text="{Binding Linea}" FontFamily="Calibri" FontWeight="Bold" FontSize="13"> 
        <TextBlock.Effect> 
         <DropShadowEffect Color="White" BlurRadius="3" ShadowDepth="0" Opacity="5" /> 
        </TextBlock.Effect> 
         </TextBlock> 
        </Grid> 
       </DataTemplate> 
      </my1:GridViewTemplateColumn.CellTemplate> 
     </my1:GridViewTemplateColumn> 
    </my1:GridView.Columns> 
</my1:GridView> 

當我打開應用程序時，CPU提高到50-60％，而不做任何事情;在這樣的速度保持，直到我關閉應用程序

有什麼我可以做，以提高性能？

在此先感謝

你可以嘗試從您的模板移除DropShadowEffect秒 - 特別是如果你在這個網格有很多細胞，不支持虛擬化。據我瞭解，你應該儘量避免同時在很多目標上使用DropShadowEffect和BlurEffect。
