I have three checkbox that I want to check the state (checkbox1
checkbox2 checkbox3

I do the following

Dim i As Integer
Dim chk As New CheckBox
For i = 1 To 3
chk = (Controls("CheckBox" & CStr(i)))
If chk.CheckState = CheckState.Unchecked Then
.....Code
End If
Next

This works if the checkbox are NOT in a Panel only. Why??

Because they are not controls in the Form but controls in the Panel. Use
this instead:

chk = YourPanel.Controls("CheckBox" & CStr(i))

Just adding to Armin. If the only checkboxes your panel contains are
the checkboxes you want to investigate you could do this (as I hate
getting controls by name):

<pseudocode>

For each ctl as Control in YourPanel.Controls
If typeof(ctl) is Checkbox andalso directcast(ctl,
Checkbox).CheckState = CheckState.Unchecked then
' Do Stuff
End If
Next

</pseudocode>
