修改TabContainer.js文件，在dijit.layout.TabController中添加函数onButtonClick，大功告成！

当然这个方法有点代价有点高，如果只是为了单独解决Grid问题，可以直接each一下Grid，修改一下就可以。

dojo.declare("dijit.layout.TabController",dijit.layout.StackController,{
        // summary:
        //      Set of tabs (the things with titles and a close button,that you click to show a tab panel).
        // description:
        //      Lets the user select the currently shown pane in a TabContainer or StackContainer.
        //      TabController also monitors the TabContainer,and whenever a pane is
        //      added or deleted updates itself accordingly.

        templateString: "
 
 
",// tabPosition: String
        //   Defines where tabs go relative to the content.
        //   "top","bottom","left-h","right-h"
        tabPosition: "top",// doLayout: Boolean
        //      TODOC: deprecate doLayout? not sure.
        doLayout: true,// buttonWidget: String
        //      The name of the tab widget to create to correspond to each page
        buttonWidget: "dijit.layout._TabButton",postMixInProperties: function(){
                this["class"] = "dijitTabLabels-" + this.tabPosition + (this.doLayout ? "" : " dijitTabNoLayout");
                this.inherited(arguments);
        },        onButtonClick: function(/*Widget*/ page){
                        // summary:
                        //   Called whenever one of my child buttons is pressed in an attempt to select a page
                this.inherited(arguments);
                dojo.forEach(page.getDescendants(),function(widget){
           if(widget.resize)widget.resize();
                        });
        },
 
//TODO: can this be accomplished in CSS?
        _rectifyRtlTabList: function(){
                //Summary: Rectify the length of all tabs in rtl,otherwise the tab lengths are different in IE
                if(0 >= this.tabPosition.indexOf('-h')){ return; }
                if(!this.pane2button){ return; }

                var maxLen = 0;
                for(var pane in this.pane2button){
                        maxLen = Math.max(maxLen,dojo.marginBox(this.pane2button[pane].innerDiv).w);
                }
                //unify the length of all the tabs
                for(pane in this.pane2button){
                        this.pane2button[pane].innerDiv.style.width = maxLen + 'px';
                }       
        }
});
