TreeTable The TreeTable control provides a comprehensive set of features to display hierarchical data. sap.ui.table/Table Specifies whether the first level is expanded. The value of the property is only taken into account if no parameter <code>numberOfExpandedLevels</code> is given in the binding information. Changes to this property after the table is bound do not have any effect unless an explicit (re-)bind of the <code>rows</code> aggregation is done. Example: <pre> oTable.bindRows({ path: "...", parameters: { numberOfExpandedLevels: 1 } }); </pre> replaced by the corresponding binding parameter <code>numberOfExpandedLevels</code>. If group mode is enabled nodes with subitems are rendered as if they were group headers. This can be used to do the grouping for an OData service on the backend and visualize this in a table. The property name of the rows data which will be displayed as a group header if the group mode is enabled Setting collapseRecursive to true means, that when collapsing a node all subsequent child nodes will also be collapsed. This property is only supported with sap.ui.model.odata.v2.ODataModel. <b>Note:</b> collapseRecursive is currently <b>not</b> supported if your OData service exposes the hierarchy annotation <code>hierarchy-descendant-count-for</code>. In this case the value of the collapseRecursive property is ignored. For more information about the OData hierarchy annotations, please see the <b>SAP Annotations for OData Version 2.0</b> specification. The root level is the level of the topmost tree nodes, which will be used as an entry point for OData services. This property is only supported when the TreeTable uses an underlying odata services with hierarchy annotations. This property is only supported with sap.ui.model.odata.v2.ODataModel The hierarchy annotations may also be provided locally as a parameter for the ODataTreeBinding. Fired when a row has been expanded or collapsed by user interaction. Only available in hierarchical mode. Index of the expanded/collapsed row Binding context of the expanded/collapsed row Flag that indicates whether the row has been expanded or collapsed Expands one or more rows. A single index or an array of indices of the rows to be expanded Collapses one or more rows. A single index or an array of indices of the rows to be collapsed Collapses all nodes (and lower if collapseRecursive is activated) Expands all nodes starting from the root level to the given level 'iLevel'. Only supported with ODataModel v2, when running in OperationMode.Client or OperationMode.Auto. Fully supported for <code>sap.ui.model.ClientTreeBinding</code>, e.g. if you are using a <code>sap.ui.model.json.JSONModel</code>. Please also see <code>sap.ui.model.odata.OperationMode</code>. the level to which the trees shall be expanded Checks whether the row is expanded or collapsed. The index of the row to be checked Returns an array containing the row indices of all selected tree nodes (ordered ascending). Please be aware of the following: Due to performance/network traffic reasons, the getSelectedIndices function returns only all indices of actually selected rows/tree nodes. Unknown rows/nodes (as in "not yet loaded" to the client), will not be returned. Sets the selection of the TreeTable to the given range (including boundaries). Beware: The previous selection will be lost/overridden. If this is not wanted, please use "addSelectionInterval" and "removeSelectionInterval". Please be aware, that the absolute row index only applies to the tree which is visualized by the TreeTable. the start index of the selection range the end index of the selection range
