I have many checkbox binding nullable bool values and when I press on the control, if it's set to null, I have to press twice to get true. Is it possible to have true as the first value or false as default when I have null for all the checkbox, for example with a style?
I've tried with this before, and it works:
<CheckBox IsThreeState="False" IsChecked="{Binding MY_NULLABLE_PROPERTY, TargetNullValue=false}"/>
but I would like a generic solution for each control
EDITED:
I need to handle the problem for checkbox inside datagrid as well
