* TBoundColumn class
*
* TBoundColumn represents a column that is bound to a field in a data source.
* The cells in the column will be displayed using the data indexed by
* {@link setDataField DataField}. You can customize the display by
* setting {@link setDataFormatString DataFormatString}.
*
* If {@link setReadOnly ReadOnly} is false, TBoundColumn will display cells in edit mode
* with textboxes. Otherwise, a static text is displayed.
*
* When a datagrid row is in edit mode, the textbox control in the TBoundColumn
* can be accessed by one of the following two methods:
* <code>
* $datagridItem->BoundColumnID->TextBox
* $datagridItem->BoundColumnID->Controls[0]
* </code>
* The second method is possible because the textbox control created within the
* datagrid cell is the first child.
