<datagrid.columnheaderstyle> <style targettype="datagridcolumnheader"> <setter property="contenttemplate"> <setter.value> <datatemplate> <checkbox x:name="headercheckbox" content="{binding}" checked="checkboxchanged" unchecked="checkboxchanged"/> </datatemplate> </setter.value> </setter> </style> </datagrid.columnheaderstyle>
