c# - How do I know whether to use a style or override a control template? -

This question is inspired by my WPF development and other situations. How do I know if it's a new control template? Is it enough to set a style on a control to override some default behavior against?

More strongly, in the above question, the author should know how everything works except the authored boxitim when it is selected (the code given below is printed again) except for the background property Should they override the control tempers for this?

  style target type = "{x: type list box item}" & gt; & Lt; Setter property = "content" value = "{binding path = name}" /> & Lt; Setter property = "margin" value = "2" /> & Lt; Style.Triggers & gt; & Lt; Trigger Property = "Iceded" value = "true" & gt; & Lt; Setter property = "fontwhite" value = "bold" /> & Lt; Setter property = "font size" value = "18" /> & Lt; Setter property = "background" value = "yellow" /> & Lt; Setter property = "foreground" value = "red" /> & Lt; / Catalyst & gt; & Lt; /Style.Triggers> & Lt; / Style & gt; Styles can be thought of very close to CSS styles in HTML  

if you do Want to change the basic properties of a control such as background, foreground or whatever properties are displayed, then one style is exactly what you need. Styles allow you to apply triggers to animations, a style Is also enough.

If you think that you want to change the internal behavior / internal workings on the control then a control template that you want. For example, if you want to change how a button is used by adding some type of grid behavior, then using a control template is forward.
