function CustomSort(ASortProc: TdxTreeViewNodeCompareProc; AData: NativeInt; ARecurse: Boolean = True): Boolean;

Parameters

Name	Type	Description
ASortProc	TdxTreeViewNodeCompareProc

A custom comparison routine.

| | AData | NativeInt |

Specifies a pointer to additional data for the custom comparison routine. This parameter is intended to be backward compatible with the TTreeView control.

| | ARecurse | Boolean |

If True , the function sorts nodes at all nesting levels in the Tree View. If False , the function sorts only root level nodes.

Returns

Type	Description
Boolean

True if the sort operation is successful; otherwise, False.

Remarks

You can handle the Tree View’s OnCompare event to implement a custom node sorting algorithm.

Note

If you need to sort nodes in an individual branch, call the AlphaSort or CustomSort method of the branch’s root node.
