Tutorial on Embedding Control Functions into Columns of a DataGrid – Vernon Nabb

During this discussion an Interface definition is defined (IHostControl) which supports the implementation of customized Controls that may be embedded within a DataGrid or directly placed on a Windows Form.
The original problem required standard or customized Controls to be made available for columns of a DataGrid or placed on a form. These Controls are to behave identically in both locations.
To reduce the development effort and complexity for each Control, the following strategy was implemented. A wrapper class per environment was implemented which controlled any customized/standard Control which supports the IHostControl interface. Any Control could implement this interface.
The tutorial shall discuss and demonstrate the implementation of the above.
