C# asp.net 动态生成ImageButton控件及其单击事件，单击控件事件不执行，各位高手帮帮忙解决问题有30加分

在Page_Load中调用DynamicTable()(动态生成控件方法)
private void DynamicTable(int rows, int rowsPerPage, int indexRow, int currentPage, string[] id, string[] name, string[] url, string[] price, string[] sprice)
{ …… ImageButton imageButtonCommodity1 = new ImageButton();
imageButtonCommodity1.ID = id[currentPage * 24 + i * 4];//替换为商品ID
imageButtonCommodity1.Click += new System.Web.UI.ImageClickEventHandler(ImageButtonDynamic_Click);
……
}
单击事件
protected void ImageButtonDynamic_Click(object sender, ImageClickEventArgs e)
{ ImageButton btn = (ImageButton)sender;
string id = btn.ID; //这里就可以获得按钮的ID
GetPicInfo getp = new GetPicInfo();
getp.UpdateProductClickCount(id);//商品点击量加1
Response.Redirect("~/商品展示.aspx");
}

Answer 1

public void test()
{
ImageButton ib = new ImageButton();
ib.ImageUrl = "";
ib.Click += new ImageClickEventHandler(ib_Click);
DataPanel.Controls.Add(ib);
}

void ib_Click(object sender, ImageClickEventArgs e)
{
Response.Write("<script>alert('成功了!')</script>");
}

我这样写可以触发这click事件啊
click+= 直接Tab键试试？

Answer 2

imageButtonCommodity1.AutoPostBack = true;

Answer 3

DynamicTable 中，new了一个控件后增加一个属性
ImageButton.AutoPostBack=true;
让他允许post提交
