Initializes a new DataTreeGrid instance.

Attaches the specified item to this control instance.

Signals the beginning of a set of updates within the items collection, in order to temporarily remove automatic user interface refreshes during this time, for optimization purposes. When the updates are complete, call EndUpdateItems()()() method to refresh the user inteface and to revert to its standard behavior.

Returns a value that indicates whether the specified item may be moved down in the collection, optionally with its entire following children array, and optionally ensuring preserving the current parent item.

Returns a value that indicates whether the specified item may be moved up in the collection, optionally with its entire following children array, and optionally ensuring preserving the current parent item.

Collapses all parent nodes in the hierarchy.

Continues asynchronous presentation data load, if it was in progress and paused.

Default item comparison for sorting items based on their content.

Signals the end of a set of updates within the items collection initiated by a BeginUpdateItems()()() call, in order to refresh the user interface.

Resets any invalid indentation values in order to obtain a valid node hierarchy.

Expands all parent nodes in the hierarchy.

Iterates the expandable items in the hierarchical collection.

Iterates the leaf items in the hierarchical collection.

Iterates the root items in the hierarchical collection.

Counts the currently visible selected items in the hierarchy and all their child items.

Enumerates the currently visible selected items in the hierarchy and all their child items.

Searches for the specified item and returns its zero-based index in the collection.

Moves the specified item down in the collection, optionally with its entire following children array, and optionally ensuring preserving the current parent item.

Moves the specified range of items from the specified index to a new index in the collection. You may call EnsureValidHierarchy()()() after this operation completes to preserve hierarchical collection validity.

Moves the specified item up in the collection, optionally with its entire following children array, and optionally ensuring preserving the current parent item.

Builds the visual tree for the DataTreeGrid when a new template is applied and updates appropriate internal properties of the control.

Raises the AsyncPresentationCompleted event.

Raises the AsyncPresentationStarted event.

Raises the ItemCollectionChanged event.

Raises the ItemPropertyChanged event.

Pauses asynchronous presentation data load, if it was in progress.

Switches the two specified ranges of items in the collection.

Updates the IsActuallyCollapsible property values for all the managed items, if needed, based on the current runtime conditions.

Identifies the CollapsibilityMaxCount dependency property.

Identifies the ExpanderTemplate dependency property.

Identifies the IndentationUnitSize dependency property.

Identifies the IsAsyncPresentationEnabledMinCount dependency property.

Identifies the IsAsyncPresentationEnabledPageSize dependency property.

Identifies the IsAsyncPresentationEnabled dependency property.

Identifies the Items dependency property.

Gets or sets the children count limit for parent nodes in order to be collapsible and expandable from the user interface; null by default, indicating that no limit applies. This is a dependency property.

Gets or sets the template used for displaying node expanders in the DataTreeGridColumn cells. This is a dependency property.

Gets or sets the indentation left padding used for each hierarchical level in the view. This is a dependency property.

Gets or sets a value that indicates whether asynchronous presentation mode is enabled (true by default). This is a dependency property.

Gets or sets the number of items to be initially loaded synchronously when using asychronous presentation mode within the control (having IsAsyncPresentationEnabled property set to true). This is a dependency property.

Gets or sets the number of items to be loaded synchronously as one step when using asychronous presentation mode within the control (having IsAsyncPresentationEnabled property set to true). This is a dependency property.

Gets the item at the specified index in the collection.

Gets a collection of DataTreeGridItem objects that represent the individual items in the DataTreeGrid control. This is a dependency property.

Raised when the asynchronous presentation operations are completed, during component initialization and when the source item collection changes.

Raised when the asynchronous presentation operations start, during component initialization and when the source item collection changes.

Occurs when the data item collection within the control changes.

Occurs when a data property value of an item within the control changes.
