新版.32 的YUI-EXT包含了GIRD事件机制的重要升级。许多新事件现在可以用了，监听事件的机制也改变了（尽管它仍然向后兼容）。
侦听事件的方法
鉴于 YAHOO.util.CustomEvent只提供简单的访问，Grid和相关的对象扩展了新的方法来侦听事件，这些事件你应该是熟悉的。它们是：
addListener(eventName, fn, scope, override) - "eventName" should be one of the events defined below. "fn" is the function to call when the event occurs. "scope" is an optional object providing the scope (this) of the function. "override" is whether or not to apply that scope and is only there for backwards compatibility. removeListener(eventName, fn, scope) -移除前先提交的事件侦听 on(eventName, fn, scope, override) - addListener 快捷方式这些方法与YAHOO.uitl.Event一样，有相同的署名（signatures）。
onRowSelect事件的侦听：
var sm = grid.getSelectionModel(); sm.addListener('rowselect', myHandler);这是GIRD暴露事件的列表和参数简介：
- "this" 指的是Grid对象； - "e" 指的是 YAHOO.ext.EventObject (常规化事件对象) ，除了Drag & Drop对象是标准浏览器事件对象。- "dd" 指的是Grid的YAHOO.ext.GridDD对象。译注：下面事件解释以原文方式提供以便读者准确理解：
cellclick - (this, rowIndex, columnIndex, e) - Fires when a cell is clicked celldblclick - (this, rowIndex, columnIndex, e) - Fires when a cell is double clicked rowclick - (this, rowIndex, e) - Fires when a row is clicked rowdblclick - (this, rowIndex, e) - Fires when a row is double clicked headerclick - (this, columnIndex, e) - Fires when a header is clicked rowcontextmenu - (this, rowIndex, e) - Fires when a row is right clicked headercontextmenu - (this, columnIndex, e) - Fires when a header is right clicked beforeedit - (this, rowIndex, columnIndex, e) - Fires just before editing is started on a cell afteredit - (this, rowIndex, columnIndex, e) - Fires immediately after a cell is edited bodyscroll - (scrollLeft, scrollTop) - Fires when the grid's body is scrolled columnresize - (columnIndex, newSize) Fires when the user resizes a column. startdrag - (this, dd, e) - Fires when row(s) start being dragged enddrag - (this, dd, e) - Fires when a drag operation is complete dragdrop - (this, dd, targetId, e) - Fires when dragged row(s) are dropped on a valid DD target dragover - (this, dd, targetId, e) Fires while row(s) are being dragged. "targetId" is the id of the Yahoo.util.DD object the selected rows are being dragged over. dragenter - (this, dd, targetId, e) - Fires when the dragged row(s) first cross another DD target while being dragged dragout - (this, dd, targetId, e) - Fires when the dragged row(s) leave another DD target while being dragged新闻热点
