为动态创建的按钮生成事件处理程序 [英] generating the event handlers for dynamically created buttons

问题描述

hi



我创建了动态按钮，并向其中添加了一个事件处理程序，并且该按钮以最佳方式工作.


我的示例代码是:

hi



i had created the dynamic button and added an event handler to it , and it was working in the best way.


my sample code is:

Button btn = new Button();
     btn.ID = "btn";
     btn.Text = "Button";
     btn.Click += new System.EventHandler(btn_Click);

     this.form1.Controls.Add(btn);

在单击按钮时，iam会获得良好的结果


我的问题是
我已经创建了表并使用C#.net编程动态添加了按钮，这里一切都很好，我也生成了事件处理程序，但是它不起作用

示例代码:

here iam getting the good result when button is clicked


my problem is
i had create the table and added the buttons dynamically with C#.net programming, and everything is fine here,i had generated the eventhandler also, but it is not working

sample code:

TableCell cell = new TableCell();
                if (j == 0)
                {
                    Button b = new Button();
                    b.Text = dt.Rows[i][j].ToString();
                    b.ID = i + "," + j+"Button";
                    b.Click += new EventHandler(b_Click);
                    cell.Controls.Add(b);
                    row.Cells.Add(cell);
                }

所以请帮帮我

推荐答案

我猜测您不是在回发时重新创建动态表，按钮等.

需要重新创建动态添加的控件，以使回发方法和视图状态正确运行.

I am guessing that you are not recreating the dynamic table, button etc on postback.

Dynamically added controls need to be recreated in order for postback methods and viewstate to function correctly.
