     Currently I am using RadCombobox with EnableLoadOnDemand="True" and CheckBoxes="True".Loading Items using OnItemsRequest Event. After postback, selected RadComboBox values are not persisting. Is it not supported in latest version also? Is there any solution for this issue in future release.

     <telerik:RadComboBox ID="pCompany" Width="300px" runat="server" EnableLoadOnDemand="True"
                                        ShowMoreResultsBox="true" EnableVirtualScrolling="true" ItemsPerRequest="10" OnItemsRequested="pCompany_ItemsRequested"
                                        CheckBoxes="true" EnableCheckAllItemsCheckBox="true" OnSelectedIndexChanged="ppCompany_SelectedIndexChanged"
                                        AutoPostBack="true" Height="140px">

    I am afraid that using both LoadOnDemand and Checkboxes is not a supported scenario. The reason is that RadComboBox's items loaded on demand are not accessible on the server which is needed for the CheckBox feature as specified in the RadComboBox Checkbox Support help article. This scenario has been researched and it is concluded as not supported, so there is no solution for it.
