* TEditCommandColumn class

* TEditCommandColumn will create an edit button if a cell is not in edit mode.
* Otherwise an update button and a cancel button will be created within the cell.
* The button captions are specified using <b>EditText</b>, <b>UpdateText</b>
* and <b>CancelText</b>.
*
* The buttons in the column can be set to display as hyperlinks or push buttons
* by setting the <b>ButtonType</b> property.
*
* When an edit button is clicked, the datagrid will generate an <b>OnEditCommand</b>
* event. When an update/cancel button is clicked, the datagrid will generate an
* <b>OnUpdateCommand</b> or an <b>OnCancelCommand</b>. You can write these event handlers
* to change the state of specific datagrid item.
