ajax Combobox not firing event when combobox is empty
<p>In my .aspx I've written the following:</p>

<pre><code>&lt;ajaxToolkit:ComboBox ID="cmbAddressAlias" runat="server" DropDownStyle="Simple"      AutoCompleteMode="Suggest" CaseSensitive="false" AutoPostBack="true" RenderMode="Inline" Width="170px" CssClass="cmbProvince" OnSelectedIndexChanged="cmbAddressAlias_SelectedIndexChanged"&gt;           &lt;/ajaxToolkit:ComboBox&gt;
</code></pre>

<p>It's binding correctly (datasource dynamically binded) and it raises event too, while changing index.</p>

<p>However it's not raising the event when I manually clear the combobox text.</p>

<p>If currently combobox having text "ASP" then I manually select that entire text and using del key I am deleting but it is not raising event for me. When I change index it automatically raises the event.</p>

<p>I need to raise the event while combobox is empty.</p>
