wpf在样式中查找内部网格
我有一个在 xaml 中定义的按钮样式，里面有一个故事板和一个网格。故事板将网格的不透明度设置为 0.1。问题是如何通过代码恢复它。我想我可以访问网格并将不透明度设置为 1，但我找不到通过 C# 获取网格的方法。
这是代码：
xaml：
<Style x:Key="BevelWLButton" TargetType="{x:Type Button}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}" x:Name="bbtemplate">
<ControlTemplate.Resources>
<Storyboard x:Key="FadeOut" >
<DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Opacity)" Storyboard.TargetName="grid">
<EasingDoubleKeyFrame KeyTime="0" Value="1"/>
<EasingDoubleKeyFrame KeyTime="0:0:0.3" Value="0.05"/>
</DoubleAnimationUsingKeyFrames>
</Storyboard>
</ControlTemplate.Resources>
<Grid x:Name="grid">
-------------- up is the grid i find
</Style>
按钮是由代码创建的，并且样式
在此处正确设置，我开始故事板：
var story = btn.Template.Resources["FadeOut"] as Storyboard;
if (story != null)
{
story = story.Clone();
story.Begin(btn,btn.Template);
}
但是当我尝试时，
currentButton.Resources["grid"]; or currentButton.Template.Resources["grid"];
结果为空。所以，我无法重新建立不透明度
有什么想法吗？
提前致谢。
I have a button style defined in xaml, inside i have an storyboard and among other things a grid. The storyboard set the opacity of the grid to 0.1. The question is how to restore it via code. I think i can access the grid and set the opacity to 1 but i can not find a way to get the grid via c#.
Here is the code:
xaml:
<Style x:Key="BevelWLButton" TargetType="{x:Type Button}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}" x:Name="bbtemplate">
<ControlTemplate.Resources>
<Storyboard x:Key="FadeOut" >
<DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Opacity)" Storyboard.TargetName="grid">
<EasingDoubleKeyFrame KeyTime="0" Value="1"/>
<EasingDoubleKeyFrame KeyTime="0:0:0.3" Value="0.05"/>
</DoubleAnimationUsingKeyFrames>
</Storyboard>
</ControlTemplate.Resources>
<Grid x:Name="grid">
-------------- up is the grid i find
</Style>
the buttons are created by code and the style is setted properly
here i begin the storyboard:
var story = btn.Template.Resources["FadeOut"] as Storyboard;
if (story != null)
{
story = story.Clone();
story.Begin(btn,btn.Template);
}
but when i try to
currentButton.Resources["grid"]; or currentButton.Template.Resources["grid"];
the result is null. So, i can not restablish opacity
Any Idea?
Thanks in advance.
