PHP 클래스 Prado\Web\UI\WebControls\TDataGridColumn

TDataGridColumn serves as the base class for the different column types of the {@link TDataGrid} control. TDataGridColumn defines the properties and methods that are common among all datagrid column types. In particular, it initializes header and footer cells according to {@link setHeaderText HeaderText} and {@link getHeaderStyle HeaderStyle} {@link setFooterText FooterText} and {@link getFooterStyle FooterStyle} properties. If {@link setHeaderImageUrl HeaderImageUrl} is specified, the image will be displayed instead in the header cell. The {@link getItemStyle ItemStyle} is applied to cells that belong to non-header and -footer datagrid items. When the datagrid enables sorting, if the {@link setSortExpression SortExpression} is not empty, the header cell will display a button (linkbutton or imagebutton) that will bubble the sort command event to the datagrid. Since v3.1.0, TDataGridColumn has introduced two new properties {@link setHeaderRenderer HeaderRenderer} and {@link setFooterRenderer FooterRenderer} which can be used to specify the layout of header and footer column cells. A renderer refers to a control class that is to be instantiated as a control. For more details, see {@link TRepeater} and {@link TDataList}. Since v3.1.1, TDataGridColumn has introduced {@link setEnableCellGrouping EnableCellGrouping}. If a column has this property set true, consecutive cells having the same content in this column will be grouped into one cell. Note, there are some limitations to cell grouping. We determine the cell content according to the cell's {@link TTableCell::getText Text} property. If the text is empty and the cell has some child controls, we will pick up the first control who implements {@link \Prado\IDataRenderer} and obtain its {@link \Prado\IDataRenderer::getData Data} property. The following datagrid column types are provided by the framework currently, - {@link TBoundColumn}, associated with a specific field in datasource and displays the corresponding data. - {@link TEditCommandColumn}, displaying edit/update/cancel command buttons - {@link TDropDownListColumn}, displaying a dropdown list when the item is in edit state - {@link TButtonColumn}, displaying generic command buttons that may be bound to specific field in datasource. - {@link THyperLinkColumn}, displaying a hyperlink that may be bound to specific field in datasource. - {@link TCheckBoxColumn}, displaying a checkbox that may be bound to specific field in datasource. - {@link TTemplateColumn}, displaying content based on templates. To create your own column class, simply override {@link initializeCell()} method, which is the major logic for managing the data and presentation of cells in the column. 파일 보기 프로젝트 열기: pradosoft/prado 1 사용 예제들
