Add Attribute to CheckBoxList ListItem at runtime?

[CK]

Hi All,
I have an asp:CheckBoxLis t. it is databound to a datatable at runtime;

private void chklstStatuses_ DataBinding(obj ect sender, EventArgs e)

{

chklstStatuses. DataSource = BillingInvoiceU til.GetStatuses ();

chklstStatuses. DataTextField = "StatusName ";

chklstStatuses. DataValueField = "InvoiceStatusI D";

}

I need to add an attribute to each list item,
"onClick=javasc ript:setFilter( this);"

I can not get it to work. I tried two different methods in two different
events, in chklstStatuses_ DataBinding & in chklstStatuses_ PreRender.

I try it like this

for(int x = 0; x != chklstStatuses. Items.Count; x++)

{

ListItem li = chklstStatuses. Items[x];

li.Attributes.A dd("onClick","j avascript:setFi lter(this);");

}

doesn't work and I also tried
IEnumerator chklstEnumerato r;

ListItem li;

chklstEnumerato r = chklstStatuses. Items.GetEnumer ator();

while(chklstEnu merator.MoveNex t())

{

li = (ListItem)chkls tEnumerator.Cur rent;

li.Attributes.A dd("onClick","j avascript:setFi lter(this);");

}

Neither one of these methods renders the attribute. I a compile fine and i
get no runtime or javascript errors in either case. I view the page source
and the attribute just doesn't seem to render.
Can anyone help?

Thanks,
~CK
