    I have the following ComboBox on my page but although the Text value is persisted, the selected value is not. Therefore my grid loads all items regardless of what is in the ComboBox when the page loads. What do I need to change?

    <telerik:RadComboBox runat="server" DataSourceID="AllWaterSystems" DataTextField="displayName" DataValueField="pwsid" EmptyMessage="Water System" Filter="Contains" Width="350" ID="SelectedWaterSystem" EnableItemCaching="True" OnClientDropDownOpening="RefreshHeight">
        <HeaderTemplate>
            <ul>
                <li class="col1">PWSID</li>
                <li class="col2">Name</li>
            </ul>
        </HeaderTemplate>
        <ItemTemplate>
            <ul>
                <li class="col1"><%# DataBinder.Eval(Container.DataItem, "PWSID") %></li>
                <li class="col2"><%# DataBinder.Eval(Container.DataItem, "Name") %></li>
            </ul>
        </ItemTemplate>
    </telerik:RadComboBox>

    Hi Rayne,

    The Selected values are not persisted by default, but you can handle that manually, keeping the selected values in a datafield which values will be used on load. This issue is discussed in details in the following thread where you can also see a sample configuraton of the suggested approach:
