按钮动态创建的点击事件不起作用

问：

我想创建许多具有不同文本和背景的按钮，当我单击这些按钮时，我想将此按钮的文本和颜色传输为另一个函数的参数。

但是 Dynamicaly Created Button 在单击时调用 PostBack，而不是执行他的 on click 事件

这是我用于创建按钮的代码隐藏：

for (int i = 0; i < elem; i++)

            {
                decimal vol = Convert.ToDecimal(DT.Rows[Liste[j]].ItemArray[3].ToString());

               

                TableRow rowct = new TableRow();
                TableCell CT1 = new TableCell();


                var button = new Button
                {
                    ID = "Button" + Moda + j,
                    CssClass = "TimatButton",

                    CommandArgument = DT.Rows[Liste[j]].ItemArray[6].ToString(),
                    Text = DT.Rows[Liste[j]].ItemArray[1].ToString(),
                    BackColor = System.Drawing.ColorTranslator.FromHtml(DT.Rows[Liste[j]].ItemArray[6].ToString()),
                    ForeColor = System.Drawing.ColorTranslator.FromHtml(DT.Rows[Liste[j]].ItemArray[8].ToString()),
                    BorderColor = System.Drawing.ColorTranslator.FromHtml(DT.Rows[Liste[j]].ItemArray[6].ToString()),
                    CommandName = "Load_Items",
                                       


            };
                
                if (vol != 1)
                { button.CssClass = "TimatCutButton"; }

               

                CT1.Controls.Add(button);

                AsyncPostBackTrigger Trig = new AsyncPostBackTrigger();
                Trig.ControlID = button.ID;
                Trig.EventName = "Click";
                UpdatePanel2.Triggers.Add(Trig);

                j += 1;

  protected void Load_Items(object sender, EventArgs e)
        {

            Button a = sender as Button;
            System.Diagnostics.Debug.WriteLine(a.Text);
            
        }

其实void Load_Items只是为了测试代码

                    </ContentTemplate>
                          
                                </asp:UpdatePanel>
                    


                
                 </div>

在此之前，我的代码可以在 FrontSide 创建的按钮上运行良好。

非常感谢您的帮助
