DevExpress ASPxSplitter ClientSideEvents-PaneExpanded 时间用法

在webform中的devexpress aspxsplitter中套用了jquery-easyui的 tabs id=tt

<div id="tt" class="easyui-tabs" data-options="tools:'#tab-tools'" style="width:100%;height:100%">
                                    </div>

在aspxsplitter调整大小等操作时，我们需要用代码调整tab的大小随splitter变化，使用ClientSideEvents-PaneExpanded等事件，如下：

  <dx:ASPxSplitter ID="ASPxSplitter1" runat="server"   Width="100%" Height="100%" ClientSideEvents-PaneExpanded="function(s, e) { $('#tt').resize(); } "  ClientSideEvents-PaneCollapsed="function(s, e) { $('#tt').resize(); } " >
            <Styles>
                   <SeparatorButton 
                    Border-BorderColor="Black"  
                    BorderBottom-BorderWidth="2" 
                    Border-BorderStyle="Solid" 
                    BorderTop-BorderWidth="1" 
                    BorderLeft-BorderWidth="1" BorderRight-BorderWidth="1" 
                    >
                    <Border BorderColor="Black" BorderStyle="Solid" BorderWidth="0"></Border>
                    <BorderBottom BorderWidth="2px"></BorderBottom>
                </SeparatorButton>
            </Styles>
            <Panes>
                <dx:SplitterPane Size="16%"  ShowCollapseBackwardButton="True" >
                <PaneStyle>
