类似于这个问题,ASP.Net动态命令按钮事件不会触发,但问题略有不同.

下面提供的是我的代码的(非常)精简版本.

    private void RenderDataItems()
    {
        pnlDataItems.Controls.Clear()

                b.Text = "Selected Item";
            }
            else

            pnlDataItems.Controls.Add(b);
        }
    }

    private void SelectItem(object sender, CommandEventArgs e)
    {
        hdnDataListID.Value = e.CommandArgument.ToString();
        RenderDataItems();
    }
