Question

作业地点＃1：

// imports

const routes: Routes = [{
  path: 'page1',
  component: Page1Component
}];

@NgModule({
  imports: [RouterModule.forChild(routes)],
  exports: [RouterModule]
})
export class Page1RoutingModule {

  public static routes = routes;
}

作业地点＃2：

                case 1:
                    TableCell tCell = new TableCell();

                    if (!strlil_image_1.Contains("blank"))
                    {
                        var img = new ImageButton();
                        img.ID = "imglil_image_" + strlil_image_1.Replace("images/inventory/", String.Empty).Replace(".", "_");
                        img.AlternateText = "Image " + i.ToString();
                        img.ImageUrl = strlil_image_1;
                        img.Width = 40;
                        img.Height = 40;
                        img.Click += img_Click;
                        tCell.Controls.Add(img);
                }
                else
                {
                    var img = new Image();
                    img.ID = "imglil_image_" + i.ToString();
                    img.AlternateText = "Image " + i.ToString();
                    img.ImageUrl = strlil_image_1;
                    img.Width = 40;
                    img.Height = 40;
                    tCell.Controls.Add(img);
                }

                tRow1.Cells.Add(tCell);
                break;

相关功能：

                TableCell tCell = new TableCell();

                if (arrList[i].mark_color_group)
                {
                    tCell.Style.Add("border", "1px solid brown");
                    imgMainPic.ImageUrl = arrList[i].image_name.ToString();
                }

                var img = new ImageButton();
                img.ID = "imglil_color_group_" + arrList[i].color_id;
                img.AlternateText = "Image " + arrList[i].color_id;
                img.ImageUrl = arrList[i].image_name;
                img.Width = 40;
                img.Height = 40;
                img.Click += img_Click;
                tCell.Controls.Add(img);

                tRow.Cells.Add(tCell);

当页面最初运行时，ImageButton使用正确的图像绘制光标=手等。单击时，页面循环，Page_Load（子和主）加载，但是，当单步执行代码时，函数为ImageButton未运行。这是我难倒的地方。

帮助!!!

好像你在

创建了一个图像的本地img

            else
            {
                var img = new Image();
                img.ID = "imglil_image_" + i.ToString();
                img.AlternateText = "Image " + i.ToString();
                img.ImageUrl = strlil_image_1;
                img.Width = 40;
                img.Height = 40;
                tCell.Controls.Add(img);
            }

            tRow1.Cells.Add(tCell);
            break;

然后休息？永远不会分配事件。在其他人之前的条件是否真的是真的吗？

ImageButton OnClick（以编程方式）触发，但不允许检查点 - 演练显示OnClick事件不可执行
