Ext.Net 中TextField的KeyPress及Value的处理【总结】

（1）TextField 中KeyPress 事件：

 

       <ext:TextField 
              ID="txtCon" 
              runat="server"                                    
              LabelAlign ="Right" 
              FieldLabel ="con"
              Width ="250px"                                     
              Height="25px"                                     
              EnableKeyEvents="true"
              >  

             <Listeners>                                
                    <KeyPress  Handler="if (e.getKey()==Ext.EventObject.ENTER){Ext.net.DirectMethods.TextKeyPress();e.stopEvent();}" />                

                   <%--<SpecialKey Handler="alert('You pressed on the \'special\' key with code ' + e.getKey())" />--%>                        
             </Listeners>
    </ext:TextField>

(2)由ID  Set  TextField 的值：

                 X.GetCmp<TextField>(“TextFieldID”).Text =newValue；                  //如上：：TextFieldID=“txtcon”

    或者是使用javascript  :

          <script type="text/javascript">
        
        function ClearPanelItemJS(ctrlids_str，Value_Str)
        {
            if (ctrlids_str != null && ctrlids_str.length > 0)
            {
                var ctrlids = ctrlids_str.split(';');
                var  value=Value_Str.split(';');
                for (i=0; i<ctrlids.length; i++)
                {
                    var ctrl = document.getElementById(ctrlids[i]);
                    if (ctrl != null) ctrl.value = value[i];
                };          
            }
        }
    </script>

在Server端Event中添加 ：X.ResourceManager.AddScript("ClearPanelItemJS('" + ctrlids + "'，"+value+");");  //传递ＩＤ，Ｖａｌｕｅ参数
