RadComboBox ItemRequested Event is not firing

[ALAN NEMARIC]

Hi All,
I am using load on demand in radcombobox.
The problem is when i type first letter in the combobx then the event is not firing. and when i type second letter then the event fires.
and also when i click on the radcombobx then some time the event fires and some time it is not firing.
what could be the problem>
I am posting the code:

<telerik:RadComboBox ID="cmbFromPortfolio" EnableVirtualScrolling="true" EnableLoadOnDemand="True" ShowMoreResultsBox="false" OnClientSelectedIndexChanged="SamePortfolio" OnClientBlur="FromOperationalDisable" runat="server" EmptyMessage="Please Select" AutoPostBack="true" Height="200px" Width="92%" Enabled="false">
 </telerik:RadComboBox>

and the event handler is

cmbFromPortfolio.ItemsRequested += new RadComboBoxItemsRequestedEventHandler(cmbFromPortfolio_ItemsRequested);

// And the Event Handler code is

private void cmbFromPortfolio_ItemsRequested(object sender, RadComboBoxItemsRequestedEventArgs e)
{
try
{
//Code to fill the combobox
}
catch(Exception ex)
{
//Exception Handling code here
}
}

Let me know where is the problem.
Thanks in advance.

Hi ALAN NEMARIC,

This is a really annoying bug in the IE8 browser.

Fortunately in the latest version of RadComboBox we managed to work it around in 98% of the cases, so I suggest you download the latest internal build and try it out.

Sincerely yours,

I've loaded the latest hot fix and the problem still exist.  Any other suggestions?

Using IE8 the Telerik RadComboBox samples are failing to work properly also; http://demos.telerik.com/aspnet-ajax/combobox/examples/populatingwithdata/autocompletesql/defaultcs.aspx

Is there a fix for this?

Thanks,

Hi Phil,

I just checked the demo and it worked properly. The version there is now Q2 2010, which we released yesterday.

Could you please test it again on your side and let me know how it goes?
