哪位高手帮我看看,DataGrid1的事件为什么不执行。
代码如下:

protected static string id = null;
protected static string id2 = null;private void Page_Load(object sender, System.EventArgs e)
{
// 在此处放置用户代码以初始化页面
if (!IsPostBack)
{
ReadAndPrintClass1();
ReadAndPrintClass2();
}

只要你将控件的事件绑定到相关的函数就能执行的呀
这个应该是ASP.NET 的事件触发模型
1.数据绑定正常,DataGrid1和DataGrid2都能正常显示数据,DataGrid2的所有事件都正常触发。
2.将DataGrid2全部删除,DataGrid1就全部正常,这样看来事件绑定也应该是正常的。
3.调试的时候我把一些代码注释掉了,那些代码我就没有贴上来,下面我把全部代码贴上。
