Hi sugeet_s,

You can get the ID using chkListInterest.ClientID & "_" & position(0 to ?):


<%@ Page Language="VB" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script runat="server">

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)

Dim s As String = "<b>Listitems ID:</b><br/>"
Dim i As Integer
For i = 0 To chkListInterest.Items.Count - 1
s = s & chkListInterest.ClientID & "_" & i.ToString()
s = s & "<br/>"
Next

lblMsg.Text = s

End Sub

Protected Sub btSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs)

Dim s As String = "<b>Selected Listitems ID:</b><br/>"
Dim i As Integer
For i = 0 To chkListInterest.Items.Count - 1
If chkListInterest.Items(i).Selected Then
s = s & chkListInterest.ClientID & "_" & i.ToString()
s = s & "<br/>"
End If
Next

lblMsg.Text = s

End Sub

</script>
