trouble with CheckBoxBoxList outside a DataList!!

[naijacoder]

I have this checkboxlist out side a Datalist below:-

<asp:checkboxlist id="chkList" AutoPostBack="True" Runat="server"
DataValueField="ProductFeatureID"
DataTextField="Feature"
OnSelectedIndexChanged="Check_Clicked"></asp:checkboxlist></

And the event that fires after when the checkBoxList is clicked
-------------------------------------------------------
Sub Check_Clicked(ByVal sender As Object, ByVal e As EventArgs) Handles
chkList.SelectedIndexChanged
'print.Text = "Selected Item(s):<br><br>"
Dim i As Integer
For i = 0 To chkList.Items.Count - 1
If chkList.Items(i).Selected Then
P &= "_" & chkList.Items(i).Value
'Tested it here to print it to the screen
print.Text = P & "<br>"
End If
Next

End Sub


This is my link below in the DataList( What i want to get is the value
selected below which is ok but after selecting a checkbox i want to
append only the checbox value the user has selected but i noticed that
after the Check_Clicked fires i can't get the right values appended to
the link.
What i really want is to get the CheckBoxLixt values appended to the link below after POSTBACK which i have set in the ChecKboxList control.But it seems the Datalist doesn't get the values after postback

Any help please?

<a href='addtocart.aspx?productid=<%#
DataBinder.Eval(Container.DataItem, "ProductID") & "&Features=" & P &
","
%>'>Add To cart</a>

Try this: Create a Public or Protected function named, say, SelectedFeatures:

Protected Function SelectedFeatures() As String
    Dim P As String
    For I As Integer = 0 To chkList.Items.Count - 1 
        If chkList.Items(i).Selected Then 
            P &= "_" & chkList.Items(i).Value 
        End If 
    Next
    Return P
End Function

Then change the code in your DataList to this:

<a href='addtocart.aspx?productid=<%# DataBinder.Eval(Container.DataItem, "ProductID") & "&Features=" & SelectedFeatures() & "," %>'>Add To cart</a>

Thx Phil for the reply. But after trying ur suggestion it still doesn't FIRE.
The thing is that after a checkbox is clicked this method fires :-

Sub Check_Clicked(ByVal sender As Object, ByVal e As EventArgs) Handles
chkList.SelectedIndexChanged
'print.Text = "Selected Item(s):<br><br>"
Dim i As Integer
For i = 0 To chkList.Items.Count - 1
If chkList.Items(i).Selected Then
P &= "_" & chkList.Items(i).Value
'Tested it here to print it to the screen
print.Text = P & "<br>"
End If
Next
End Sub

And what i think is that since the CheckBoxlist is outside the DataList i can't seem to retrieve the variable after postback to append it to the QueryString.
What i did is was added the function you recommended and changed the link accordingly but didn't fire..
Is there still something 'm missing?
Thanks
