Seting control value on the same stackPanel WPF
I have a situation:
DataGrid with TemplateColumn. Template contains Stack panel with CheckBox and TextBox. What I want is when I press CheckBox then TextBox which is on the same StakcPanel set value to 1.
So in simple
CheckBox -> IsChecked==true -> Set TextBox value to 1 (TextBox on the same StackPanel as CheckBox)

I try with RelativeSource but not work.
Thanks For help.
