ASP：按钮的Click事件不会被解雇 [英] asp:Button Click event not being fired

问题描述

我动态的ASP表中添加行。在该表的每一行，我也包括具有SelectProduct_Click事件的按钮。

I am dynamically adding rows in an asp table. In each row of the table I am also including a button which has a SelectProduct_Click event.

问题是，即使我注册单击事件，是不是被解雇的事件。

The problem is that even though I am registering the click event, the event is not being fired.

该按钮以这种方式被添加

The button is being added in this way:

btnSelect = new Button();
btnSelect.ID = "btnSelect";
btnSelect.CommandArgument = od.ProductId;
btnSelect.Click += new EventHandler(this.SelectProduct_Click);
btnSelect.CssClass = "button";
btnSelect.Text = "Select";
cell = new TableCell();
cell.Controls.Add(btnSelect);
row.Cells.Add(cell);

我怎样才能让我的按钮发射的点击？

How can I get my button to fire on click?

推荐答案

创建（并重新创建）动态控制的最佳位置是在的OnInit 事件处理程序。

The best place to create (and re-create) dynamic controls is in the OnInit event handler.
