当页面进行回发时，如点击按钮，以上事件都会重新执行一次，这时的执行顺序为：
1. OnPreInit
2. OnInit
3. OnInitComplete
4. OnPreLoad
5. Page_Load
6. OnLoad
7. Button_Click
8. OnLoadComplete
9. OnPreRender
可以看到，Button_Click事件位于OnLoad之后执行，可以测试一下：
public partial class TestControls : System.Web.UI.Page { static int count = 0; protected void Page_Load(object sender, EventArgs e) { Response.Write(count+ "Page_Load <br />"); count++; } protected override void OnPreInit(EventArgs e) { base.OnPreInit(e); Response.Write(count + "OnPreInit <br />"); count++; } protected override void OnInit(EventArgs e) { base.OnInit(e); Response.Write(count + "OnInit <br />"); count++; } protected override void OnLoad(EventArgs e) { base.OnLoad(e); Response.Write(count + "OnLoad <br />"); count++; } protected override void OnPreLoad(EventArgs e) { base.OnPreLoad(e); Response.Write(count + "OnPreLoad <br />"); count++; } protected override void OnLoadComplete(EventArgs e) { base.OnLoadComplete(e); Response.Write(count + "OnLoadComplete <br />"); count++; } protected override void OnInitComplete(EventArgs e) { base.OnInitComplete(e); Response.Write(count + "OnInitComplete <br />"); count++; } protected override void OnUnload(EventArgs e) { base.OnUnload(e); } protected override void OnDataBinding(EventArgs e) { base.OnDataBinding(e); Response.Write(count + "OnDataBinding <br />"); count++; } protected override void OnPreRender(EventArgs e) { base.OnPreRender(e); Response.Write(count + "OnPreRender <br />"); count++; } protected void btnGraphics_Click(object sender, EventArgs e) { //Bitmap bmp = new Bitmap(10, 10); //Graphics g = Graphics.FromImage(bmp); Response.Write(count + "btnGraphics_Click <br />"); count++; } }
ASP.NET Page执行顺序如：OnPreInit()、OnInit()
