Grid中某列选中，加载另一个grid,选中撤消，移除另一个grid

//testProjectGrid的SM为testProjectSm。
testProjectSm.on("rowselect",function(){
		$s('testProjectDetailGrid').baseParams = {formIdStr:$sel('testProjectGrid').get('id')}; //向testProjectDetailGrid传递参数
		$s('testProjectDetailGrid').load(); //加载testProjectDetailGrid
	});
//选中取消移除testProjectDetailGrid	testProjectSm.on("rowdeselect",function(){
		$s('testProjectDetailGrid').removeAll();
	});
