DevExpress ASPxCombobox 组件的学习与应用

ASPX:

 <script type="text/javascript">
        function OnVesselCodeChange(VesselCode)
        {
          cbVoyageSearch.PerformCallback(VesselCode.GetValue().toString()) ;  //服务回调。
        }
        function ClearSearchCtrlValue()
        {
          cbVoyageSearch.SetValue("");
          tbBLNoSearch.SetValue("");
          cbVesselCodeSeach.SetValue("");
        }
    </script>

<dx:ASPxComboBox id="cbVesselCodeSeach" runat="server" style="left: 57px; position: absolute; top: 12px" ValueType="System.String" ClientInstanceName="cbVesselCode" Width="89px"  >
            <ClientSideEvents SelectedIndexChanged="function(s, e) {
OnVesselCodeChange(s);   //客户端选择某个内容，发生变化时，调用服务器ajax.
 
}"   />
        </dx:aspxcombobox>
        <dx:ASPxComboBox ID="cbVoyageSearch" runat="server" OnCallback="cbVoyage_Callback" Style="left: 171px;
            position: absolute; top: 13px" Width="79px"  >
        </dx:ASPxComboBox>
