Ajax Combobox Selection

[Joseph Baker]

I have 2 combo boxes on my page.  when I change the first one, it loads the 2nd combo data (using a template).  However, the SELECTED item displayed in the combo box does not change.

telerik:RadComboBox ID="cmbCarrier" runat="server" DataSourceID="sqlCarrier"
        DataTextField="Name" DataValueField="CARRIER_ID" AutoPostBack="True" Width="388px" CausesValidation="False">
        <CollapseAnimation Duration="200" Type="OutQuint" />
    </telerik:RadComboBox>
    Select Contract:
    <telerik:RadComboBox  ID="cmbContract" runat="server" DataSourceID="sqlContracts" MarkFirstMatch="true" OnDataBound="cmbContract_DataBound" EnableLoadOnDemand="true" HighlightTemplatedItems="true"   Width="420px"  OnItemDataBound="cmbContract_ItemDataBound" OnSelectedIndexChanged="cmbContract_SelectedIndexChanged" CausesValidation="False" >
                                <HeaderTemplate>
                            <table style="width: 100%; text-align: left">
                                <tr>
                                    <td style="width: 125px;">
                                        Contract ID
                                    </td>
                                    <td style="width: 125px;">
                                        Carrier
                                    </td>
                                    <td style="width: 125px;">
                                        Description
                                    </td>
                                </tr>
                            </table>
                        </HeaderTemplate>
                        <ItemTemplate>
                            <table style="width: 100%; text-align: left">
                                <tr>
                                     <td style="width: 125px;">
                                        <%# DataBinder.Eval(Container.DataItem, "CONTRACT_ID") %>
                                    </td>
                                    <td style="width: 125px;">
                                        <%# DataBinder.Eval(Container.DataItem, "Name") %>
                                    </td>
                                    <td style="width: 125px;">
                                        <%# DataBinder.Eval(Container.DataItem, "DESCRIPTION") %>
                                    </td>

                                </tr>
                            </table>
                        </ItemTemplate>
        <CollapseAnimation Duration="200" Type="OutQuint" />
    </telerik:RadComboBox>

    protected void cmbContract_ItemDataBound(object sender, Telerik.Web.UI.RadComboBoxItemEventArgs e)
    {
        {
            e.Item.Text = ((DataRowView)e.Item.DataItem)["CONTRACT_ID"].ToString() + "; " + ((DataRowView)e.Item.DataItem)["Name"].ToString() + "; " + ((DataRowView)e.Item.DataItem)["DESCRIPTION"].ToString();
            e.Item.Value = ((DataRowView)e.Item.DataItem)["CONTRACT_ID"].ToString() + "; " + ((DataRowView)e.Item.DataItem)["Name"].ToString() + "; " + ((DataRowView)e.Item.DataItem)["DESCRIPTION"].ToString();
        }

    }

I simply want the first item in the list to be displayed.

Hi Joseph Baker,

To provide you with a solution we need some more information . Could you please paste here the code you use to populate the second combobox based on first combo or ideally open a support ticket and send us a simple and running project illustrating the problem? Also, could you send some more information about the ajax settings - the definition of RadAjaxPanel or RadAjaxManger you use.
