For some reason the onitemsrequested event is no longer firing when I use Q1 2010 for .net 4. This code worked perfectly well in previous versions

<telerik:RadComboBox ID="RadComboBoxCountry" runat="server"
EnableItemCaching="True" EnableLoadOnDemand="True"
onitemsrequested="RadComboBoxCountry_ItemsRequested" Width="250px"
Skin="Vista">
<CollapseAnimation Duration="200" Type="OutQuint" />
</telerik:RadComboBox>

protected void RadComboBoxCountry_ItemsRequested(object o, Telerik.Web.UI.RadComboBoxItemsRequestedEventArgs e)

{

PopulateCountries(e.Text);

}

private void PopulateCountries(string e)

{

List<Country> lst = new List<Country>();

lst = timeZoneManager.FilterCountries(e);

this.RadComboBoxCountry.Items.Clear();

if (lst.Count > 0)

{

foreach (Country c in lst)

{

this.RadComboBoxCountry.Items.Add(new Telerik.Web.UI.RadComboBoxItem(c.CountryName, c.CountryName));

}

has anything changed that I need to be aware of ?

Hi Mark,

Just to clarify the problem.
Please find attached a project and a video how the RadComboBox ItemsRequested event behaves with version 2010.1.309.40.

Does the attached project work at your side? If yes - could you please modify it so we can see the exact problem?

and the codebehind

{

}

private void PopulateCountries(string e)

{

List<Country> lst = new List<Country>();

lst = timeZoneManager.FilterCountries(e);

this.RadComboBoxCountry.Items.Clear();

if (lst.Count > 0)

{

foreach (Country c in lst)

{

this.RadComboBoxCountry.Items.Add(new Telerik.Web.UI.RadComboBoxItem(c.CountryName, c.CountryName));

}

its exactly the same as my previous version which works, but in this case the event will not fire

Hi,

We just tried your code and it worked at our side. Please find attached our test project. See the 'Default2.aspx' page.
Does it work at your side? What is the exact browser that you use?

Hi Mark,

As I can see the subscription of your license has expired in 2009, while IE9 was launched in 2010. We design software based around the current frameworks, browsers, etc., but those will change over time and we cannot guarantee that the software you purchased will function just as well in IE9 as it did in IE7, and other similar issues will not appear. This is why we offer subscription licenses, that provide you with the great benefit of receiving all the new versions for free. As you have left your subscription to lapse, you can now upgrade to the latest version at a discounted price, that we offer to our existing customers. When you upgrade you will also receive a free subscription for 1 year.

I hope this helps.

Best wishes,
Emilia
