IDataErrorInfo

IDataErrorInfo

---

System.ComponentModel (system.dll)

interface

This interface is implemented by classes that wish to provide additional error information to the user interface in data-binding scenarios. The Error property gives an error message that indicates what is wrong with the object. The Item property (which is the indexer in C#) allows the UI to find the specific error message for the property with a given name .

As an example, it is implemented by System.Data.DataView and the System.Windows.Forms.DataGrid uses it to display error information.

 public interface  IDataErrorInfo  {  // Public Instance Properties  public string  Error  {get; }    public string  this  {get; } }
