我有一个自定义控件类型:<Grid> ... </Grid>
和Grid.BitmapEffect属性。如何通过C#代码(例如,在事件中)更改此控件(网格)中的BitmapEffetc?
代码示例 - 自定义控件的一部分:
[...]
<Grid Background="#FFE5AA">
<Grid.RowDefinitions>
<RowDefinition Height="62*"/>
<RowDefinition Height="15*"/>
<RowDefinition Height="23*"/>
</Grid.RowDefinitions>
<Grid.BitmapEffect>
<OuterGlowBitmapEffect GlowColor="#459E5A" GlowSize="13" Noise="0" Opacity="0.9" />
</Grid.BitmapEffect>
<Border Grid.Column="0" Grid.Row="0" Grid.RowSpan="3" BorderBrush="#F5B903" BorderThickness="1,1,1,1" >
</Border>
[...]
然后在Window.xaml:
<controls:MyControl Name="Control1" Cursor="Hand" MouseDown="Control1_MouseDown" />
然后在C#中:
private void Control1_MouseDown(object sender, MouseButtonEventArgs e)
{
//there i want to change Control1.BitmapEffect
}

myGrid.BitmapEffect = null;
PS:请注意,BitmapEffect被认为已过时,应使用Effect。
以下是基于您的样本的示例,该示例完全正常(在我的机器上):只要我在Grid中单击,效果就会消失。
XAML:
<Window x:Class="WpfCsApplication1.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Window1" Height="300" Width="300">
<Grid Background="#FFE5AA" Margin="10" MouseDown="Grid_MouseDown" x:Name="myGrid">
<Grid.RowDefinitions>
<RowDefinition Height="62*"/>
<RowDefinition Height="15*"/>
<RowDefinition Height="23*"/>
</Grid.RowDefinitions>
<Grid.BitmapEffect>
<OuterGlowBitmapEffect GlowColor="#459E5A" GlowSize="13" Noise="0" Opacity="0.9" />
</Grid.BitmapEffect>
<Border Grid.Column="0" Grid.Row="0" Grid.RowSpan="3" BorderBrush="#F5B903" BorderThickness="1,1,1,1" >
<TextBlock>Test</TextBlock>
</Border>
</Grid>
</Window>
代码隐藏:
public partial class Window1 : Window {
public Window1() {
InitializeComponent();
}
private void Grid_MouseDown(object sender, MouseButtonEventArgs e) {
myGrid.BitmapEffect = null;
}
}
在你的例子中,你写道://there i want to change Control1.BitmapEffect
。请注意,您需要更改 Grid 的BitmapEffect,而不是 Control1 的BitmapEffect。
