Blanket “中等”数据具有约束力+有效性
原标题:Blanket "immediate" data binding+validation

I have a fairly routine setup with some check boxes and numeric up/downs bound to a data class through a BindingSource. The default behaviour seems to be that nothing is updated or validated until the control loses focus, and for this application that s useless. Is there some way to make it such that every single blessed control on that form validates and updates immediately after any change, instead of on focus loss?

In Advance Databindings properties of your control, Go to on binding property(like Text for TextBox) and on (Data Source Update Model)combo, Select OnPropertyChange instead of OnValidation.
