c# - Child dataGrid dataContext is being set to parent dataGrid causing binding Error -

i have parent , kid datagrid as:

<datagrid name="dispositionncrsgrid" itemcontainerstyle="{staticresource maindatagriditemstyle}" itemssource="{binding path=parentsource}" > <datagrid.rowdetailstemplate> <datatemplate> <datagrid selectionmode="single" itemssource="{binding myitemsource}" style="{dynamicresource maindatagridstyle}" horizontalalignment="center" >

now problem kid grid looking myitemsource within parentsource instead of current viewmodel.

how reset kid datagrid access info current viewmodel

if want myitemsource detail datagrid same view model main datagrid takes parentsource can utilize relativesource binding , go visual tree find parent datagrid , utilize datacontext

itemssource="{binding relativesource={relativesource mode=findancestor, ancestortype={x:type datagrid}}, path=datacontext.myitemsource}"

c# wpf datagrid
