Drag 在IE9下无法拖拽的解决方法
Drag and Drop from a Data Grid to a Form Panel
最近在做一个拖拽操作。在FF下正常。但在;IE9失败，并提示以下 警告：
ext-all.js, 行7 字符2195
SCRIPT438: 对象不支持“createContextualFragment”属性或方法
开始以为是面板没有渲染的问题。
最近竟然是IE问题。！！
解决方法在HTML页面中加入
<meta http-equiv="X-UA-Compatible" content="IE=8" />
附上自己修改的官方例子控件及最终整合到项目过程中的代码 。
使用：new Ext.DDGridPanel({
height : 200,

this.items = [
this._createFirstGrid(),
this._createSecGrid()
];
this.bbar = [
'->', // Fill
{
text : 'Reset Example',
scope:this,
handler : function() {
var form = this.findByType('form')[0];
form.getForm().reset();
var grid = this.findByType('grid')[0].getStore();
//这里只能重新获取值？
