Problem reseting CheckBoxList when not checked.

[Patrick.O.Ige]

I have CheckboxList Databinded below and that works fine and i can get the
selected values after PostBack.
But what i have noticed is that when you select a checkbox i.e lets say 3 of
them and later unselect them the last one u unselect remains printed out on
the screen.
How can i reset Checkboxlists back to NULL.
I need to do this becos i'm passing the values to a QueryString and if the
unselect and remains in the queryString its a problem.
Any ideas?
<asp:checkboxli st id="chkList" AutoPostBack="T rue" Runat="server"
DataValueField= "ProductFeature ID" DataTextField=" Feature"
OnSelectedIndex Changed="Check_ Clicked"></asp:checkboxlis t></td>

Sub Check_Clicked(B yVal sender As Object, ByVal e As EventArgs)
'print.Text = "Selected Item(s):<br><br >"
Dim i As Integer
Dim a As String

Dim P As String = ""
For i = 0 To chkList.Items.C ount - 1

If chkList.Items(i ).Selected Then
P &= "," & chkList.Items(i ).Value
print.Text = P
End If
Next
End Sub

print.Text =""
