[Tex/LaTex] Set page number in all Chapter start pages with KOMA-Script

chapterskoma-scriptpage-numberingreport

I'm using the KOMA-Script to define my headings and I would like to show only the page number in the chapter start pages. I got this by creating a new style and using it with \thispagestyle{ChapterStyle} after the \chapter{}, but I have many chapters. Is there a way to add only the page number automatically to all the chapter start pages? Thanks for your attention and help!
Here follows what I've done:

\documentclass[a4paper,12pt,twoside]{report}
\usepackage{lipsum}

\usepackage[automark,headsepline,headtopline,footsepline,footbotline,nouppercase]{scrpage2}
\pagestyle{scrheadings}
\clearscrheadfoot
\renewcommand{\chaptermark}[1]{\markboth{#1}{}}
\chead{\normalfont{\thechapter. \headmark}}
\cfoot{\pagemark}

% To define a page style
\deftripstyle{ChapterStyle}{}{}{}{}{\pagemark}{}

\begin{document}

\chapter{Chapter One}
\thispagestyle{ChapterStyle}
\lipsum

\chapter{Chapter Two}
\lipsum

\chapter{Chapter Three}
\lipsum

\chapter{Chapter Four}
\lipsum

\end{document}

Best Answer

In report the page style for \chapter is plain by default. To change this you either need to change the plain page style, which may well have undesired side effects for other formatting in your document, or to patch the \chapter command to use your own style:

\usepackage{etoolbox}
\patchcmd{\chapter}{plain}{ChapterStyle}{}{}

If you had been using scrreprt instead then there would be the easier mechanism of issuing

\renewcommand*{\chapterpagestyle}{ChapterStyle}
