    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
