Public Methods

Method Description
BeginEdit ( ) : void
CancelEdit ( ) : void
CreateChildView ( DataRelation relation ) : DataView
CreateChildView ( DataRelation relation, bool followParent ) : DataView

Returns a System.Data.DataView for the child System.Data.DataTable with the specified System.Data.DataRelation.
CreateChildView ( string relationName ) : DataView
CreateChildView ( string relationName, bool followParent ) : DataView

CreateChildView(DataRelation)
Delete ( ) : void
EndEdit ( ) : void
Equals ( object other ) : bool Checks for same reference instead of equivalent DataView or Row. Necessary for ListChanged event handlers to use data structures that use the default to object.Equals(object) instead of object.ReferenceEquals to understand if they need to add a PropertyChanged event handler.
GetHashCode ( ) : int
this ( int ndx ) : object

Gets or sets a value in specified column.

Uses either DataRowVersion.Default or DataRowVersion.Original to access Row

this ( string property ) : object

Gets the specified column value or related child view or sets a value in specified column.
