How to loop thru each controls ?

Hi all,

I have a 42 groupboxes in a panel, each groupbox has 3 check boxes in it.

The 42 groupboxes are actually in a panel, and the panel is on the second
tab page of a tab control...

What I need to do is to find out the value of each checkbox (i.e. checked or
not), can anyone tell me how to do it?

I think it would be easier if I can create an array of groupbox like in vb6,
but it seems it's not avaliable in .net ....

Thanks~

You will have to recursively enumerate the controls. Check out the
implementation of 'FindControl' here:

Accessing controls by their names or indices

You don't say how you identify each checkbox, but try this (not tested, but
I think it works):

Dim al As New List(Of CheckBox)

Foreach gb as GroupBox in panel.Controls
    Foreach rb as CheckBox in gb.Controls
       If rb.Checked Then
            al.Add(rb)
        End If
    Next
Next
