新版.32 的YUI-EXT包含了GIRD事件機制的重要升級。許多新事件現在可以用了，監聽事件的機制也改變了（盡管它仍然向后兼容）。
偵聽事件的方法
鑒于 YAHOO.util.CustomEvent只提供簡單的訪問，Grid和相關的對象擴展了新的方法來偵聽事件，這些事件你應該是熟悉的。它們是：
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偵聽 on(eventName, fn, scope, override) - addListener 快捷方式這些方法與YAHOO.uitl.Event一樣，有相同的署名（signatures）。
onRowSelect事件的偵聽：
var sm = grid.getSelectionModel(); sm.addListener('rowselect', myHandler);這是GIRD暴露事件的列表和參數簡介：
- "this" 指的是Grid對象； - "e" 指的是 YAHOO.ext.EventObject (常規化事件對象) ，除了Drag & Drop對象是標準瀏覽器事件對象。- "dd" 指的是Grid的YAHOO.ext.GridDD對象。譯注：下面事件解釋以原文方式提供以便讀者準確理解：
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新聞熱點
