[CLOSED] [1.3] Duplicate Items on Combo

[MP]

Hi,

Not sure if this is a bug but when I insert items to a combo box, duplicate items show up.

<%@ Page Language="C#" %>

<script runat="server">

Hi,

Personally, I would prefer to do not mix populating the ComboBox with Store and Items. I would choose a single approach.

Though to avoid the issue you could set up

AlwaysMergeItems="false"

for the ComboBox.
