 * difference is that the active datagrid uses callbacks instead of postbacks

 * There are also active datagrid columns to work with the TActiveDataGrid, which are
 * - {@link TActiveBoundColumn}, the active counterpart to {@link TBoundColumn}.
 * - {@link TActiveLiteralColumn}, the active counterpart to {@link TLiteralColumn}.
 * - {@link TActiveCheckBoxColumn}, the active counterpart to {@link TCheckBoxColumn}.
 * - {@link TActiveDropDownListColumn}, the active counterpart to {@link TDropDownListColumn}.
 * - {@link TActiveHyperLinkColumn}, the active counterpart to {@link THyperLinkColumn}.
 * - {@link TActiveEditCommandColumn}, the active counterpart to {@link TEditCommandColumn}.
 * - {@link TActiveButtonColumn}, the active counterpart to {@link TButtonColumn}.

/**
 * TActiveLiteralColumn class
 *
 * TActiveLiteralColumn represents a static text column that is bound to a field in a data source.
 * The cells in the column will be displayed with static texts using the data indexed by
 * {@link setDataField DataField}. You can customize the display by
 * setting {@link setDataFormatString DataFormatString}.
 *
 * If {@link setDataField DataField} is not specified, the cells will be filled
 * with {@link setText Text}.
 *
 * If {@link setEncode Encode} is true, the static texts will be HTML-encoded.
 *
 * This is the active counterpart to the {@link TLiteralColumn} control. For that purpose,
 * if sorting is allowed, the header links/buttons are replaced by active controls.
 *
 * Please refer to the original documentation of the {@link TLiteralColumn} for usage.
