the above code shows style datagridcolumnheader. it's working fine mouseenter , mouseleave effect there small things don't like. there have right below here.

the problem here each cell in header has rounded border. want between 2 cells in header 1 single straight line. also, when click on 1 of cells in header, there no arrow showing sorting , no highlight column that's sorted.

does has template edit myself achieve want? or parts have edit?

by default datagridcolumnheaderspresenter draws additional column header of full width in background of datagrid header. leaving out dummy header want. add style styles:

    <style targettype="{x:type datagridcolumnheaderspresenter}">         <setter property="template">             <setter.value>                 <controltemplate targettype="{x:type datagridcolumnheaderspresenter}">                     <grid>                         <itemspresenter />                     </grid>                 </controltemplate>             </setter.value>         </setter>     </style>
