TdxCustomListView.OnCompare Event

Allows you to implement a custom item sort.

property OnCompare: TdxListViewCompareEvent read; write;

Remarks

This event occurs every time two items are about to be compared during a sort operation.

The AItem1 and AItem2 parameters identify the items to be compared. Use their properties to determine their order in the sorted list. The table below explains which values you should assign to the ACompare parameter to achieve a specific item order:

Value	Description
A negative integer value	`AItem1` is positioned before `AItem2`.
0	`AItem1` is positioned before `AItem2`.
A positive integer value	`AItem` is positioned after `AItem2`.
