    Hi all

    I have a RadComboBox:

    <telerik:RadComboBox ID="radCmbRegioniFilter" runat="server"
     Filter="Contains" AutoPostBack="true" EnableLoadOnDemand="True"
     onchange="Page_BlockSubmit = false;"
     OnClientItemsRequesting="radCmbRegioniFilter_OnClientItemsRequesting">
     <WebServiceSettings Method="GetRegionAll" Path="~/controls/OnDemand.asmx" />
    </telerik:RadComboBox>

    When I click on the combobox the data are load correctly.

    If I execute a postback and I click on the combobox, the webservice is call but the combobox contains only the selected item and blank in others rows. If I click again on combobox I see all data.

    Why?

    Thanks
