Ext让grid选中第一行，并且触发点击事件

grid.getSelectionModel().selectRow(0);
grid.fireEvent("rowclick",this,0,Ext.EventObject);

给grid绑定事件即可：

listeners:{
scope:this,
rowclick:function(grid,rowIndex,event){
var row=grid.getStore().getAt(rowIndex);
if(row && row.data){
analysisReportInfo({nameEn:row.data.nameEn});
}
},
load:function(){
this.getSelectionModel().selectRow(0);
this.fireEvent("rowclick",this,0,Ext.EventObject);
}
}

grid.getSelectionModel().selectRow(0);
grid.fireEvent('rowclick',this,0,Ext.EventObject());
