![]() The context menu allows users to delete a row or copy its data to the clipboard. This example shows how to define a cell’s context menu. Void TableView_ShowGridMenu(object sender, GridMenuEventArgs e) īarItemLinkActionBase.SetItemLinkIndex(item1, 0)ĭim item2 As BarItemLinkSeparator = New BarItemLinkSeparator()īarItemLinkActionBase.SetItemLinkIndex(item2, 1) We have a GridControl with a Tree view to show a hierarchical tree of objects. Use the bar‘s UpdateAction and specify the item name. ![]() Gets or sets whether recursive node selection is enabled. The following example renames the “Customize…” item in the summary panel: Gets or sets whether the GridControl handles notifications from the data source and updates TreeListView nodes between DataControlBase.BeginDataUpdate () and DataControlBase.EndDataUpdate () calls. To bind a cell’s context menu to a column, row, or TableView, use the default binding source or the attached GridPopupMenu.GridMenuInfo property. Examples Bind to a Column, Row, and TableView in RowCellMenuCustomizations Handle the DataViewBase.ShowGridMenu event. These properties return a BarManagerActionCollection object ( bar items, links, and actions). TreeListView.CompactModeSortElementMenuCustomizations ![]() TreeListView.CompactModeFilterMergeElementMenuCustomizations TreeListView.CompactModeFilterElementMenuCustomizations TableView.CompactModeSortElementMenuCustomizations The GridControl allows data to be grouped by an unlimited number of columns. TableView.CompactModeFilterMergeElementMenuCustomizations TableView.CompactModeFilterElementMenuCustomizations GridViewBase.GroupFooterMenuCustomizations To implement on demand node loading, handle the TreeListView.NodeExpanding event. Child nodes are dynamically created and initialized when their parent node is expanded. GridViewBase.GroupPanelMenuCustomizationsĭataViewBase.TotalSummaryMenuCustomizations In an unbound mode, you need to manually create a tree (in code or XAML). To obtain the context menu displayed within a View, use the GridViewBase.GridMenu property.

Use the ValueFactoryExtension if you specify the View property in the style. To display hierarchical data in a tree, use the TreeListView. ![]() To display data using a Card View, you should create a corresponding View object and assign it to the View property. Wpf-tree-list-calculate-custom-node-summaries/CS/CustomNodeSummaries_CodeBehind/MainWindow.xaml#L13 When the GridControl is created, it initializes the View property with a TableView object. The following code snippets (auto-collected from DevExpress Examples) contain references to the TreeListView class. You can sequentially visit nodes starting from a specified node down to the last node. To simplify managing hierarchical data (without writing additional recursive code), the TreeListView ships with an API. The only requirement is that these data objects should have common fields (columns). Nodes can be represented by objects of different types. The event arguments allow you to identify group rows and replace their display text. To do this, handle the CustomGroupDisplayText event. In this instance, it may be useful to replace the default text displayed within group rows. The information is displayed in a tree from hierarchical data structures. You can group rows using custom rules by handling the GridControl.CustomColumnGroup event. The TreeListView has the following TreeList-specific features: The TreeListView supports standard data-aware and presentation features such as data editing, sorting, filtering, summary calculation, built-in validation, unbound columns, runtime column customization and more.
