VBFlexGrid Control (Replacement of the MSFlexGrid control)

[bincong]

Update released.

When AllowMultiSelection is True and AllowSelection is False the AllowBigSelection property now controls the behavior whether multiple single selections can be done via shift+ctrl or ctrl.
When AllowBigSelection is set to False (defaults True) it is not allowed anymore and truly single selection.
That is that .SelectedRows can then return only 1 or 0.

@bincong, be aware that altering via .RowSelected(x) does not raise a MultiSelChange event.

This is fantastic, thank you!
After thorough testing, I have several follow-up observations:

1. Why does mouse-click selection trigger the MultiSelChange event twice?
Occurs once on mouse press and once on release. Note: When AllowSelection = True, it triggers only once.

2. Is it expected behavior that re-clicking an already selected row triggers MultiSelChange?
When AllowSelection = True, this does not re-trigger the event.

3. Could a BeforeMultiSelChange event be implemented?
Rationale: Setting Cancel = True in BeforeSelChange doesn't affect MultiSelChange. Additionally, Ctrl-click deselection triggers MultiSelChange but not SelChange.

Separately, I've observed anomalous behavior in BeforeSelChange:
When setting Cancel = True to block selection changes, the selection still changed.

'Test BeforeSelChange
Private Sub Form_Load()
    With VBFlexGrid1
        .Rows = 10
        .Cols = 5
        .SelectionMode = FlexSelectionModeByRow
        .AllowSelection = False
        .AllowMultiSelection = False
    End With
End Sub

Private Sub VBFlexGrid1_BeforeSelChange(ByVal NewRowSel As Long, ByVal NewColSel As Long, Cancel As Boolean)
    If NewRowSel > 5 Then Cancel = True
End Sub

Clicking the last row unexpectedly selects all rows simultaneously.
