Syntax

public class DataColumnChangedEventArgs : SelfAccumulateableEventArgs

The DataColumnChangedEventArgs type exposes the following members.

Constructors

	Name	Description
	DataColumnChangedEventArgs	Constructor.

Properties

	Name	Description
	HasRowCountDecreased	Indicates, if the row count decreased during the data change event off period. In this case it is neccessary to recalculate the row count of the table, since it is possible that the table row count also decreased in this case.
	MaxRowChanged	Upper bound (plus one) of the area of rows, which changed during the data change event off period. This in in the (plus one) convention, i.e. the value of this member is the maximum row number that changed plus one.
	MinRowChanged	Lower bound of the area of rows, which changed during the data change event off period.

Methods

	Name	Description
	Accumulate	Accumulates further data changes of a column into a already created object.
	Add	(Overrides SelfAccumulateableEventArgsAdd(SelfAccumulateableEventArgs))
	Equals	Override to ensure that only one instance of SelfAccumulateableEventArgs is contained in the accumulated event args collection. You have to override Equals in the following way: two instances of the same type, which can be merged together, should return true (and GetHashCode should then return the same value). (Inherited from SelfAccumulateableEventArgs)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object)
	GetHashCode	Override to ensure that only one instance of SelfAccumulateableEventArgs is contained in the accumulated event args collection. You have to override GetHashCode in the following way: two instances of the same type, which can be merged together, should return the same hash code (and Equals should then return true). (Inherited from SelfAccumulateableEventArgs)
	GetType	Gets the Type of the current instance. (Inherited from Object)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object)
	ToString	Returns a string that represents the current object. (Inherited from Object)
