Green for valid binding names
Red for invalid binding names
Blue for complex binding names (their children may contain valid binding names) If a control isn't linked to an attribute or if a control is linked to an invalid attribute, an error message is displayed in the Binding field and an error icon is displayed in the canvas. When a control doesn't have a valid binding, any value entered into the control in runtime is not passed on to the form payload.
