In my report control, all columns have AllowRemove = true.

I'd like to prevent my users from removing the last column, regardless of the order in which they remove the columns.

Is this currently possible?

All I can suggest is to keep a global varable to keep track of how many rows are visible to start, then increment\decrement as columns are added\removed, then do something like this:

Private Sub wndReportControl_MouseDown(Button As Integer, Shift As Integer, X As Long, Y As Long)
    Dim hitColumn As ReportColumn

    Set hitColumn = wndReportControl.HitTest(X, Y).Column
    If Not hitColumn Is Nothing Then
        If ColumnCount <= 1 Then
         &nbs p;  hitColumn.AllowRemove = False
        End If
    End If
   
End Sub

Thanks SuperMario.

I've already implemented the following code based on similar lines:

Private Sub xrcParent_ColumnOrderChanged()
Dim xrcCol As XtremeReportControl.ReportColumn
Dim iCountVisible As Long
On Error Resume Next

  ' Loop through column collection
  For Each xrcCol In xrcParent.Columns
    ' Count visible cols
    If xrcCol.Visible Then iCountVisible = iCountVisible + 1
    ' Exit Loop if more than one visible column
    If iCountVisible > 1 Then Exit For
  Next
  ' Set AllowColumnRemove based on visible columns
  xrcParent.AllowColumnRemove = (iCountVisible > 1)
 

Exit_xrcParent_ColumnOrderChanged:
  Set xrcCol = Nothing
  On Error GoTo 0
  Exit Sub
End Sub
