WPF settings control gets focus Focusmanager

The simple usage is as follows:

In the parent class container, use the attached property focusmanager.focusedelement to bind the control that needs to be forced to focus, using the following:

<grid Focusmanager. focusedelement= "{Binding elementname=btn}" >
<button x:name= "btn" content= "1234"/>

</Grid>

It is important to note that when a control uses a style or a template to override the structure of a control, this setting may be invalid, and it needs to go into the template to set
