Methods

	Name	Description
	CancelCellEdit	When overridden in a derived class, causes the column cell being edited to revert to the unedited value.
	CheckAccess	Determines whether the calling thread has access to this object. (Inherited from DependencyObject.)
	ClearValue	Clears the local value of a dependency property. (Inherited from DependencyObject.)
	Equals(Object)	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	GenerateEditingElement	When overridden in a derived class, gets an editing element that is bound to the column's Binding property value.
	GenerateElement	When overridden in a derived class, gets a read-only element that is bound to the column's Binding property value.
	GetAnimationBaseValue	Returns any base value established for a Silverlight dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject.)
	GetCellContent(DataGridRow)	Gets the Content property value for the cell at the intersection of this column and the specified row.
	GetCellContent(Object)	Gets the Content property value for the cell at the intersection of this column and the row that represents the specified data item.
	GetColumnContainingElement	Returns the column that contains the specified element.
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	GetValue	Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	NotifyPropertyChanged	Called by a specific column type when one of its properties changes and its current cells need to be updated.
	PrepareCellForEdit	When overridden in a derived class, called when a cell in the column enters editing mode.
	ReadLocalValue	Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject.)
	RefreshCellContent	Refreshes the contents of a cell in the column in response to a column property value change.
	SetValue	Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject.)
