                   CustomDataGridViewColumn Sample

                        

===============================================================================



/////////////////////////////////////////////////////////////////////////////

Use:



This sample demonstrates how to create a custom DataGridView column.





/////////////////////////////////////////////////////////////////////////////

Remark:



There're six standard DataGridViewColumn types for use as follows:



DataGridViewTextBoxColumn

DataGridViewCheckedBoxColumn

DataGridViewComboBoxColumn

DataGridViewLinkColumn

DataGridViewButtonColumn

DataGridViewImageColumn



However, developers may want to use a different control for editing on the column,

e.g. MarkedTextBox, DateTimePicker etc. This feature can be achieved in two ways:



1. Create a custom DataGridViewColumn; 



   The code in this CustomDataGridViewColumn sample demonstrates how to do this;



2. Place the editing control on the current cell when editing begins, and hide

   the editing control when the editing completes. For the details of this

   approach, please refer to the EditingControlHosting sample.





/////////////////////////////////////////////////////////////////////////////

Creation:



1. Create a MaskedTextBoxEditingControl class derive from MaskedTextBox class 

   and IDataGridViewEditingControl class, see the code in the 

   MaskedTextBoxEditingControl.vb file for the implementation details;



2. Create a MaskedTextBoxCell class derive from DataGridViewTextBoxCell class,

   see the code in the MaskedTextBoxCell.vb file for the implementation details;



3. Create a MaskedTextBoxColumn class derive from DataGridViewColumn class,

   see the code in the MaskedTextBoxColumn.vb file for the implementation details;



4. Build the program;
