SqlDependency.OnChange Event

Occurs when a notification is received for any of the commands associated with this SqlDependency object.

Namespace: System.Data.SqlClient
Assembly: System.Data (in system.data.dll)

public event OnChangeEventHandler OnChange
/** @event */
public void add_OnChange (OnChangeEventHandler value)

/** @event */
public void remove_OnChange (OnChangeEventHandler value)

In JScript, you can handle the events defined by a class, but you cannot define your own.
Not applicable.

OnChange occurs when the results for the associated command change. If you are not using OnChange, you can check the HasChanges property to determine whether the query results have changed.

The OnChange event does not necessarily imply a change in the data. Other circumstances, such as time-out expired and failure to set the notification request, also generate OnChange.
