Problem while retrieving multiple item in checkboxlist

[riteshraha]

I cant retrieve selected item from checkboxlist in asp.net project.
when i submit multiple item from checkboxlist it works fine. but when i am trying to edit this items then checkboxlist does not select the previous values that i have selected.It only selects one item. my code which i am using for edit is following:
Dim _drArticle As SqlDataReader
_drArticle = SqlHelper.Execu teReader(Config urationSettings .AppS ettings("Connec tionString"), _
CommandType.Tex t, _
"SELECT *FROM MST_ACCESS WHERE MA_MUT_ID=" & CInt(Request.Qu eryString("ArtI D")))



If _drArticle.HasR ows Then

_drArticle.Read ()
On Error Resume Next
'checkboxlist1. SelectedValue = _drArticle("MA_ MUR_ID")

Dim i As Integer
For i = 0 To checkboxlist1.I tems.Count - 1
If checkboxlist1.I tems(i).Selecte d = True Then
checkboxlist1.I tems(i).Value = _drArticle("MA_ MUR_ID")
checkboxlist1.S electedValue = checkboxlist1.I tems(i).Value

End If
Next
end if
