RadComboBox - Very Low Performance

[Kiran]

Hi,

We encounter a performance issue in IE 8 with RadComboBox for more than 2000 listitems
The performance degrades a lot and gives an error "Stop running this script? A script on this page causing IE to run slowly..."

My Radcombobox has below settings and bind dataset to this combo in page load event.

<

 

telerik:RadComboBox ID="ddlEmployee" runat="server" Width="190px" Height="100px"

 

 

EmptyMessage="Select employee " EnableLoadOnDemand="True" EnableVirtualScrolling="true"

 

 

OnItemsRequested="RadComboBox1_ItemsRequested" DataTextField="Name" DataValueField="EmpNo"

 

 

Skin="WindowsXP" OffsetX="2" AllowCustomText="True" EnableEmbeddedSkins="False"

 

 

EnableAjaxSkinRendering="False" EnableEmbeddedBaseStylesheet="False"

 

 

EnableItemCaching="True" ShowMoreResultsBox="True">

 

 

</telerik:RadComboBox>

Can someone help me how to improve the performance? 

Any suggestions would be appreciated.

Thanks & Regards,

Kiran
