I have a user control that applies a style to button, with the style containing a ControlTemplate section. Within the ControlTemplate, there are various UI elements such as an Ellipse and a Path.
If I give those elements -- the Ellipse and Path -- a name with x:Name, can I access them from code behind?
It appears the style's Ellipse and Path are not visible because I get a compile error (C#).
Am I going about this the wrong way?
Because a template can be instantiated multiple times, it's not possible to bind a generated member via x:Name
. Instead, you have to find the named element within the template applied to a control.
Given simplified XAML:
<ControlTemplate x:Key="MyTemplate">
<Ellipse x:Name="MyEllipse" />
</ControlTemplate>
You would do something like this:
var template = (ControlTemplate)FindResource("MyTemplate");
template.FindName("MyEllipse", myControl);
Or even more simply:
var ellipse = (Ellipse)myControl.Template.FindName("MyEllipse", myControl);
You can read about FrameworkTemplate.FindName
.
