What i have to do in my view model. Please help

Hi Mahesh , Thanks for your reply. Since i am using pnxcheckbox i could not use . I am asking is there any way to do it in viewmodel. like getting selected vales in an array and show that in checkbox.

Hi Monica, Try this code, "{Binding Path=Item.Name}" IsChecked="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ListBoxItem}}, Path=IsSelected,Mode=TwoWay}"> "Checked" > "{Binding DataContext.OnCheckedCommand, ElementName=myCtrl}" />
