动态生成的按钮事件为什么没有执行？
//那个按钮是在点击某个树节点后自动生成的，但是运行程序后，那个shenPiBtn按钮（有生成动态按钮），但是点击后没有执行事件处理的代码（在最后面的shenPiBtn_Click），比如

[解决办法]
protected void daishenP()
{
.............
......................
shenPiBtn.Click += new EventHandler(shenPiBtn_Click);
form1.Controls.Add(shenPiBtn);
}

你的daishenP()肯定是要在shenPiBtn_Click里执行的,但你在daishenP()里才绑定事件处理程序不是晚了吗?

[解决办法]
不能写在!ispostback里

==============================
不能在！ispostback写个函数，然后再调用吗？晕！
