Description
TDataLink is a helper class used by data-aware objects to coordinate the actions of TDataSource and TDataSet, and to respond to data events. {{#multireplace:Vcl.DBCtrls.TDataSourceLink|H21=!|H25=%|H28=(|H29=)|H2A=*|H2B=+|H2F=/|H3C=<|H3D==|H3E=>|H5B=[|H5D=]|H5E=^|H7C=|}} inherits from {{#multireplace:Data.DB.TDataLink|H21=!|H25=%|H28=(|H29=)|H2A=*|H2B=+|H2F=/|H3C=<|H3D==|H3E=>|H5B=[|H5D=]|H5E=^|H7C=|}}. All content below this line refers to {{#multireplace:Data.DB.TDataLink|H21=!|H25=%|H28=(|H29=)|H2A=*|H2B=+|H2F=/|H3C=<|H3D==|H3E=>|H5B=[|H5D=]|H5E=^|H7C=|}}.
TDataLink is a helper class used by data-aware objects to coordinate the actions of TDataSource and TDataSet, and to respond to data events.
Use TDataLink or one of its descendants in any data-aware object that implements a DataSource property to represent its link to a dataset or that needs to respond to data events.
The constructor of the data-aware object should call the constructor of TDataLink, and initialize any relevant properties. The data-aware object can then link to a TDataSource by using the DataSource property of the TDataLink.
Data-aware objects that link to a single field in a dataset should use a TFieldDataLink instead.
