dhtmlxcombo in ASP.NET UpdatePanel causes postback

I’m using a dhtmlxcombo inside an UpdatePanel in an ASP.NET 2.0 aspx page.

The combo renders correctly on the page using the following script, which is inside an UpdatePanel:

<asp:DropDownList AutoPostBack=“true”

ID=“BoatModel” runat=“server” Width=“341” OnSelectedIndexChanged=“BoatModel_SelectedIndexChanged”

DataSourceID=“BoatModelDataSource” DataTextField=“ModelName”


var z=dhtmlXComboFromSelect(“ctl00_WebPageContent_BoatModel”);



However, when I change the selection in the drop-down, the page is updated with a flicker. It looks like the UpdatePanel / ScriptManager code does not recognize the event coming from the dhtmlxcombo as it would from the select genrated by the asp:DropDownList

If I remove the dhtmlxcombo code, the page updates correctly under AJAX, without a page-flicker.

Is there any solution to make the dhtmlxcombo update the page without a flicker?

Combo is javascript object, not html select. After combo initialization the select removes.

The component has own onChange event: combo.attachEvent(“onChange”,handler);

The selected value can be got by getActualValue() method and in addition it is placed into hidden element (for form submit).
