How does WPF access controls in inline templates?

Question

for example:
<ToggleButton x:Name="FlipButton">
<ToggleButton.Template>
<ControlTemplate>
<Grid Margin="0,5,0,0">
<Path Data="M0,0 L8,8 0,16" Stroke="White">
<Path.RenderTransform>
<RotateTransform x:Name="Tag"/>
</Path.RenderTransform>
</Path>
</Grid>
</ControlTemplate>
</ToggleButton.Template>
</ToggleButton>
I want to animate the "Tag" object in the inline template at some point, but when I apply the animation, I will be prompted that the name cannot be found. Is there any way to deal with this problem?

Answer 1

You can use below code to get RotateTransform named Tag .

 RotateTransform tag = (RotateTransform)FlipButton.Template.FindName("Tag", FlipButton);  

There is a Microsoft document How to: Find ControlTemplate-Generated Elements giving a detailed description of it. By the way, if I misunderstand your question, please point out.
