GRID拖拽行的例子

---------------------GRID拖拽行的例子  单行拖拽---------------------------------------
//创建第一个GRID
var firstGrid = new Ext.grid.GridPanel({
ddGroup : 'secondGridDdGroup',//这里是第二个GRID的ddGroup
store       : firstGridStore,
enableDragDrop : true,//True表示启动对于GridPanel中选中行的拖动行为
……其他属性省略
});

//创建第二个GRID
var secondGrid = new Ext.grid.GridPanel({
ddGroup : 'firstGridDdGroup',//这里是第一个GRID的ddGroup
store       : secondGridStore,
enableDragDrop : true,//True表示启动对于GridPanel中选中行的拖动行为
……其他属性省略
});

//创建第一个GRID的ddGroup
var firstGridDropTargetEl = firstGrid.getView().el.dom.childNodes[0].childNodes[1];
var firstGridDropTarget = new Ext.dd.DropTarget(firstGridDropTargetEl, {
ddGroup    : 'firstGridDdGroup',//和第二个GRID的ddGroup相同
copy        : true,
notifyDrop : function(ddSource, e, data){
   function addRow(record, index, allItems) {
    var foundItem = secondGridStore.find('name', record.data.name);
    if (foundItem == -1) {
     firstGridStore.add(record);
     firstGridStore.sort('name', 'ASC');
     ddSource.grid.store.remove(record);
    }
   }
   Ext.each(ddSource.dragData.selections ,addRow);
   return(true);
}
)};

//创建第二个GRID的ddGroup
var secondGridDropTargetEl = secondGrid.getView().el.dom.childNodes[0].childNodes[1];
var secondGridDropTarget = new Ext.dd.DropTarget(secondGridDropTargetEl,{
ddGroup : 'secondGridDdGroup',//和第一个GRID的ddGroup相同
copy        : true,
notifyDrop : function(ddSource, e, data){
   function addRow(record, index, allItems) {
    var foundItem = secondGridStore.find('name', record.data.name);
    if (foundItem == -1) {
     secondGridStore.add(record);
     secondGridStore.sort('name', 'ASC');
     ddSource.grid.store.remove(record);
    }
   }
   Ext.each(ddSource.dragData.selections ,addRow);
   return(true);
}
});
