Cannot select the ComboBox item
<p>I have two Comboboxes where the second one is dependent upon the first one.</p>

<p>When the SelectedIndexChanged event of the first Combobox fires then the second Combobox will be enabled.</p>

<p>After the event, the second Combobox is enabled but I cannot select the ComboBox item.</p>

<p><strong>EDIT</strong></p>

<p>I use Dev express Tools</p>

<p>First Combo I load in Page_Load Event</p>

<p>I use Server Side code:</p>

<pre><code>protected void ASPxComboModule_SelectedIndexChanged(object sender, EventArgs e)
{
    LoadSecondCombo();
    LoadSecondCombo.Focus();
}
</code></pre>

<p>There is no problem in loading, but I'm unable to select 2nd combo item.</p>
