We have telerik license of version 2009.3.1314.35.
At one page, we have used radcombobox with ondemand rendering as below,
<telerik:RadComboBox ID="ddlEmployee" runat="server" Width="250px" 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>
My requirement is to enable on demand functionality for employee list. The objective is, at page load I should be able to set selectedvalue item to employee combbox and also to achieve on demand functionality in it
The above scenario works fine if I dont set selectedvalue item to combobox in page load.
My observation while debugging.
The problem with RadCombobox is that if we bind the RadCombobox on page load, and try to click in combobox text area RadComboBox1_ItemsRequested is not get fired. However, if start writing something in RadCombobox text area RadComboBox1_ItemsRequested is get fired.
Please help us to achieve this functionality in combobox.
Thanks in advance.

I would suggest that you take a look at the following help article where the Load On Demand functionality of the RadComboBox is explained in details - Load On Demand. Please keep in mind that we no longer provide support for the version of the controls that you mention as described in our Support Lifecycle Policy here.
