Question for .NET GURUs

mike_abc · January 12th, 2005, 07:31 AM

(I asked the following question on other forums but got n000 answer)

How do I retrieve the .Checked property of a checkbox in a form by cycling thru its controls collection, such as in

Dim AnyCtrl as Control

For AnyCtrl In MyForm.Controls
    if TypeOf AnyCtrl Is CheckBox then

       ?? ...get the "checked" status of the control... ???

    Next AnyCtrl

In VB6 there used to be the Controls("CheckBox") filter, which has been dumped in VB.Net :(, so how do you do the above in .NET ??

TIA

The following will work:

Code:

        Dim ctrl As Control, cb As CheckBox
        For Each ctrl In Me.Controls
            If ctrl.GetType.Name.ToLower = "checkbox" Then
                cb = CType(ctrl, CheckBox)
                Dim mssg As String
                If cb.Checked Then mssg = " is checked" Else mssg = " isn't checked"
                MessageBox.Show(cb.Name & mssg)
            End If
        Next

I appreciate it isn't quite as elegant as it could be (would be nice if you could do For Each CheckBox in Me.Controls), but it does the job.
