Accessing WPF control validation rules from code

Question

XAML:

  
      
          
              
                  <         


        

Answer 1

you need to get the Binding first before you get the rules

    Binding b=  BindingOperations.GetBinding(textboxMin,TextBox.TextProperty);
    b.ValidationRules

else you can have BindingExpression and check for HasError property

 BindingExpression be1 = BindingOperations.GetBindingExpression (textboxMin,TextBox.TextProperty);

be1.HasError
