EnableAutomaticLoadOnDemand freezes IE when accessing remotely

[Sharon]

I have implemented EnableAutomaticLoadOnDemand and can be run perfectly locally. But when I deployed it to my staging server and access it via my local IE it freezes my IE when I start typing the first character in the drop down text box. Please advise. Following is my codes:

<telerik:RadComboBox ID="RadComboBox1" runat="server"
DataTextField="Code" Height="100px"
DataValueField="ClientID" DataSourceID="SqlDataSource1" Filter="StartsWith"
DropDownWidth="500px" ShowDropDownOnTextboxClick="False"
EnableVirtualScrolling="true" ShowMoreResultsBox="true"
HighlightTemplatedItems="True" EnableAutomaticLoadOnDemand="true"
AutoPostBack="True" EmptyMessage="Enter here"
OnSelectedIndexChanged="RadComboBox1_SelectedIndexChanged"
ItemsPerRequest="10" LoadingMessage="Searching..." MaxHeight="300px"
ShowWhileLoading="False" Width="300px" ExpandDirection="Down">
</telerik:RadComboBox>

Hello Sharon,

I have seen that you have opened a support ticket on this matter. Nonetheless, could you possibly provide us with a live URL of you web site, or perhaps test the connection with your database?

In order to avoid possible misunderstanding, I suggest we continue the conversation in the support thread you have opened on this matter.

Thank you!
