我有一个WPF应用程序,我使用ControlTemplate使用大量的对象集,这里是代码:
<ControlTemplate x:Name="ControlTemplate" TargetType="{x:Type graphsharp:VertexControl}">
<Border x:Name="_border" CornerRadius="50" Width="60" Height="60" BorderThickness="0" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
<Border.Effect>
<DropShadowEffect BlurRadius="15" Direction="309" ShadowDepth="0" Color="#FF2B00FF" RenderingBias="Quality"/>
</Border.Effect>
<Border.Background>
<RadialGradientBrush GradientOrigin="0.231,0.889" RadiusX="0.517" RadiusY="0.517">
<GradientStop Color="#CCD4D3FD" Offset="1"/>
<GradientStop Color="Black"/>
</RadialGradientBrush>
</Border.Background>
<Border CornerRadius="50" Width="60" Height="60" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="0" BorderThickness="0">
<Border.Background>
<RadialGradientBrush RadiusY="0.939" RadiusX="0.982" GradientOrigin="-0.005,0.984" Center="0.417,0.539">
<RadialGradientBrush.RelativeTransform>
<TransformGroup>
<ScaleTransform CenterY="0.5" CenterX="0.5" ScaleY="1" ScaleX="1"/>
<SkewTransform AngleY="0" AngleX="0" CenterY="0.5" CenterX="0.5"/>
<RotateTransform Angle="181.901" CenterY="0.5" CenterX="0.5"/>
<TranslateTransform/>
</TransformGroup>
</RadialGradientBrush.RelativeTransform>
<GradientStop Color="#34434343" Offset="0.56"/>
<GradientStop Offset="1"/>
<GradientStop Color="#40737373" Offset="0.543"/>
<GradientStop/>
</RadialGradientBrush>
</Border.Background>
<!--Here is the problem !! -->
<ContentPresenter Content="{TemplateBinding Vertex}"
ContentTemplate="{StaticResource VertexDataTemplate}" VerticalAlignment="Center" HorizontalAlignment="Center">
<ContentPresenter.Effect>
<DropShadowEffect Color="White" BlurRadius="4" ShadowDepth="0"/>
</ContentPresenter.Effect>
</ContentPresenter>
<!--Here is the problem !! -->
</Border>
</Border>
</ControlTemplate>
使用ContentPresenter或TextBlock时,我的问题更轻,耗费更少?
答案 0 :(得分:2)
我对Graph#不是很自负,所以这个答案假设Vertex是一个字符串。如果是这种情况,那么TextBlock将是一个更轻量级的控件。
如果将字符串放在内容呈现器中(例如在Label控件中),它将自动在内容呈现器中创建一个TextBlock来托管文本。如果您只是直接使用TextBlock,那么树内的项目就少了一个。
