Enumerates rows from a master template and recursively visits child views for hierarchy rows.

Definition

Assembly:Telerik.WinControls.GridView.dll

Syntax:

public class PagedHierarchicalTraverser : IEnumerator

Inheritance: objectPagedHierarchicalTraverser

Implements: IEnumerator

Initializes traversal from the master template's current data view.

public PagedHierarchicalTraverser(MasterGridViewTemplate masterTemplate)

Parameters:masterTemplateMasterGridViewTemplate

The master template whose data view supplies the root rows.

Gets the row at the current traversal position.

public object Current { get; }

Property Value:

The current row, or null when no row is current.

Rebuilds the pending-row stack so rows are visited in their data-view order.

protected virtual void BuildRowStack()

Determines whether traversal should add a hierarchy row's child-view rows to the stack.

protected virtual bool CanStepInHierarchy(GridViewHierarchyRowInfo hierarchyRow)

The hierarchy row whose child views may be traversed.

Returns:

true by default, allowing traversal into the row's child views.

Advances to the next row and adds child-view rows when CanStepInHierarchy(GridViewHierarchyRowInfo) allows traversal.

public bool MoveNext()

Returns:

true if a row was reached; otherwise, false when traversal is exhausted.

Restarts traversal from the rows currently in the master template's data view.

public void Reset()
