how to write client side events functions for the combobox items
<pre><code>&lt;dx:ASPxComboBox ID="ASPxComboBox2" runat="server" ClientIDMode="AutoID" 
            SelectedIndex="-1" onselectedindexchanged="ASPxComboBox1_SelectedIndexChanged1" &gt; 
        &lt;ClientSideEvents SelectedIndexChanged="function(s, e) {
    grid.SelectRows();}" /&gt;            
                                 &lt;Items&gt;                                    
                                 &lt;dx:ListEditItem Text="Selecte All Rows" /&gt; 
                                 &lt;dx:ListEditItem Text="UnselectAll" /&gt;                              
                                 &lt;/Items&gt;
              &lt;/dx:ASPxComboBox&gt;
</code></pre>

<p>I want to write event for the "unselect all" item in combobox. How can I do this?</p>
