    I have a radcombobox

    <telerik:RadComboBox ID="cboReferring" runat="server" DataSourceID="dsReferringDocs"
                                DataTextField="DisplayName" DataValueField="PCPID" Width="300px" ShowMoreResultsBox="true"
                                ItemsPerRequest="10" AppendDataBoundItems="True" EnableVirtualScrolling="False"
                                EnableAutomaticLoadOnDemand="False" EmptyMessage="Select a Referring Provider"
                                TabIndex="12">
                                <Items>
                                    <telerik:RadComboBoxItem runat="server" Text="ED Admit No Doc" Value="0" />
                                </Items>
                            </telerik:RadComboBox>

    From my code behind I try to select a value by

    cboReferring.SelectedValue = coreData.Nz(dr("sReferringProviderNumber").ToString(), "")

    The only way I could get it to selected value to select an item is to turn off the 
    EnableVirtualScrolling="False"
                                EnableAutomaticLoadOnDemand="False"

    If these are set to true, then it wil not select any item.

    Hi Ryan,

    This behavior is expected. When use Load On Demand or Virtual Scrolling items are loaded on portions for better performance. That's why combo does not contain all items and selection is not working. This is a limitation of the RadComboBox.
