The LookupBindingPropertiesAttribute is used to specify the properties used with lookup-based binding, particularly ListBox and ComboBox controls.
The LookupBindingPropertiesAttribute is specified at the class level. The class can be inherited and does not allow multiple attributes on the same class.
The following code example shows properties used with lookup-based binding.
The LookupBindingPropertiesAttribute attribute must include all four members, except when unsetting values. The following code example shows the ComboBox control.
The following code example shows that a control can support both simple binding as well as list binding.
The following code example shows that the LookupBindingPropertiesAttribute attribute can be unset by specifying no arguments.
