CheckBoxList

Question

Hi ,
    I have this code, which is working fine for checkbox, which show records on button click event.

 Public Sub ChkFunc()

        If chk1.Checked = True Then

            ShowData1()

        ElseIf chk2.Checked = True Then

            ShowData2()

        End If

here, ShowData1 And ShowData2 are functions() 
And ChkFunc I am calling it on button_click event.

Now what I want is , I want to pass same function as I have passed to Checkbox...to CheckBoxList Control..i.e I want to use CheckBoxList Control instead of individual checkbox

How to do it...?

I hope I am Clear with the query..

Plz Help
Thnx
