+/**
+ * TDropDownListColumn class
+ *
+ * TDropDownListColumn 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, TDropDownListColumn will display cells in edit mode
+ * with dropdown lists. Otherwise, a static text is displayed.
+ *
+ * There are two approaches to specify the list items available for selection.
+ * The first approach uses template syntax as follows,
+ *
+ *
+ *
+ *
+ *
+ *
+ *
+ * The second approach specifies a data source to be bound to the dropdown lists
+ * by setting {@link setListDataSource ListDataSource}. Like generic list controls,
+ * you may also want to specify which data fields are used for item values and texts
+ * by setting {@link setListValueField ListValueField} and
+ * {@link setListTextField ListTextField}, respectively.
+ * Furthermore, the item texts may be formatted by using {@link setListTextFormatString ListTextFormatString}.
+ * Note, if you specify {@link setListDataSource ListDataSource}, do it before
+ * calling the datagrid's dataBind().
+ *
+ * The dropdown list control in the TDropDownListColumn can be accessed by one of
+ * the following two methods:
+ *
+ * $datagridItem->DropDownListColumnID->DropDownList
+ * $datagridItem->DropDownListColumnID->Controls[0]
+ *
+ * The second method is possible because the dropdown list control created within the
+ * datagrid cell is the first child.
