Remarks

The LookupBindingPropertiesAttribute is used to specify the properties used with lookup-based binding. The LookupBindingPropertiesAttribute is specified at the class level. The class can be inherited and does not allow multiple attributes on the same class.

Examples

The following code example shows properties used with lookup-based binding.

' The DemoControl class shows properties 
' used with lookup-based binding.
<LookupBindingProperties( _
"DataSource", _
"DisplayMember", _
"ValueMember", _
"LookupMember")> _
Public Class DemoControl
    Inherits Control
End Class

// The DemoControl class shows properties 
// used with lookup-based binding.
[LookupBindingProperties(
    "DataSource",
    "DisplayMember",
    "ValueMember",
    "LookupMember")]
public class DemoControl : Control
{
}
