Clearing check boxes in VB.NET

I'm doing an assignment for Uni and in my VB.NET form I have some checkboxes, I'm trying to loop through and clear them (I have a button which will clear the form)

My problem is that there seems to be no property I can use to set the state of a checkbox when 开发者_如何学Gonot explicitly telling VB which checkbox I want to use. for example, I can go

WineCheckBox.Checked = False

That will check the box, but I wand to DRY the code up a bit and not have to repeat this for each check box I have, this is what I was trying to do:

If TypeOf element Is CheckBox Then
    element.Checked = False
End If

I've tried using element.CheckState and element.Checked and both times I get "Checked (or CheckState) is not a member of System.Windows.Forms.Control"

I've looked through all the attributes that I can find for this and none of them seem of use to me...

Am I missing something? or is this just not possible to do

Thanks

EDIT:

this is the whole block of code:

'clear the controls
    For Each element As Control In Me.Controls
        If TypeOf element Is TextBox Then
            element.Text = ""
        End If
        If TypeOf element Is CheckBox Then
            element.Checked = False
        End If
    Next

What type have you declared element as? If its just a Control then this is a base type for CheckBox that doesn't have the checked property. Maybe try:

If TypeOf element Is CheckBox Then
    DirectCast(element,CheckBox).checked = False
End If

How about:

   For Each element As Control In Me.Controls
        If TypeOf element Is TextBox Then
            element.Text = ""
        End If
        If TypeOf element Is CheckBox Then
            Dim chk As CheckBox = CType(element, CheckBox)
            chk.Checked = False
        End If
    Next
