OK - sorry, I tried to google this, but not sure what to google. And wasn't sure how to word it in the Title either.
the listFlDay is a List(of FlowLayoutPanel)
This code works fine if it's in it's own form, but I'm trying to put it on a TabControl and now I am getting Index was out of range. Must be non-negative and less than the size of the collection.
Debugging it says listFlDay Count = 0 System.Collections.Generic.List(Of System.Windows.Forms.FlowLayoutPanel)
Everything else is giving the correct numbers.
Do I need to put TabControl in front of something? Or should I just put it back on it's own form and load that on the Tab? Any ideas - Thanks

Code:
Private Sub AddLabelDayToFlDay(ByVal startDayAtFlNumber As Integer, ByVal totalDaysInMonth As Integer)
For Each fl As FlowLayoutPanel In listFlDay
fl.Controls.Clear()
fl.Tag = 0
fl.BackColor = Color.LightGray
Next
Dim myMargin = New Padding
myMargin.All = 0
For i As Integer = 1 To totalDaysInMonth
Dim lbl As New Label
lbl.Name = $"lblDay{i}"
lbl.AutoSize = False
lbl.TextAlign = ContentAlignment.TopLeft
lbl.Margin = myMargin
lbl.Text = i
lbl.Font = New Font("Neo Sans", 14)
listFlDay((i - 1) + (startDayAtFlNumber - 1)).Tag = i
listFlDay((i - 1) + (startDayAtFlNumber - 1)).Controls.Add(lbl)
flDays.SetFlowBreak(lbl, True)
lbl.BackColor = Color.White
If lbl.BackColor = Color.White Then
listFlDay((i - 1) + (startDayAtFlNumber - 1)).BackColor = Color.White
End If
If New Date(currentDate.Year, currentDate.Month, i) = Date.Today Then
listFlDay((i - 1) + (startDayAtFlNumber - 1)).BackColor = Color.DimGray
lbl.BackColor = Color.DimGray
End If
Next
