I'm trying to make a WebDropDown with lazy loading like the sample at http://help.infragistics.com/NetAdvantage/ASPNET/2010.3?page=WebDropDown_Lazy_Loading.html .

The event fire fine and the dataloads, however that the DropDownOpening client event keeps firing after I drop it down for the first time.

It happens in both Firefox 4 and IE 8. I'm using build 10.3.20103.2134

I've attached my sample project. The page in question is ClientEvents.aspx .

Here is a quick view of my code:

code behind:

 public partial class ClientEvents : System.Web.UI.Page
    {
        DataTable colors = SampleData.GetColorDataTable();

        protected void WebDropDown1_ItemsRequested(object sender, Infragistics.Web.UI.ListControls.DropDownItemsRequestedEventArgs e)
        {
            WebDropDown1.DataSource = colors;
            WebDropDown1.DataBind();
        }
    }

aspx markup:

<ig:WebDropDown ID="WebDropDown1" runat="server" Width="200px"
            TextField="ColorName" ValueField="ColorId"
            onitemsrequested="WebDropDown1_ItemsRequested">
            <ClientEvents DropDownOpening="WebDropDown1_DropDownOpening" />       
        </ig:WebDropDown>

java-script:
function WebDropDown1_DropDownOpening(sender, eventArgs)
{
    var wdd = $find("WebDropDown1");
    wdd.loadItems();
}
