+/**

+ * TEditCommandColumn class

+ *

+ * TEditCommandColumn contains the Edit command buttons for editing data items in each row.

+ *

+ * 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.
