Answer:

The following snippet shows you how you can gain access to the ErrorProvider of a control to change its properties, or replace it entirely:

      // For some Control pControl, retrieve its data bindings

      foreach(Binding aBinding in pControl.DataBindings) {

        // Cast the binding to an IdeaBladeBinding

        IdeaBladeBinding binding = aBinding as IdeaBladeBinding;

        if (binding != null && binding.PropertyName == "SomeBindingPropertyName") {

          // e.g. Change blinking to never blink.

          ErrorProvider errorProvider = binding.ErrorProvider;

          errorProvider.BlinkStyle = ErrorBlinkStyle.NeverBlink;

          // or

          // e.g. Replace ErrorProvider entirely

          binding.ErrorProvider = ModifiedErrorProvider;       

        }

      }

If, however, you are interested in modifying the default exception-handling behavior of a DevForce data binding, please consult the section in the Developer’s Guide titled “Modifying the Default Error Handling Behavior of the Binding.” This section describes a couple of ways to do this as well as an example of how you can replace the ControlBindingDescriptor’s Error event with your own handler.

Question:

How can I change DevForce’s UI behavior in response to a data validation failure?  I don’t want the flashing exclamation point!
