Question

我继承了这个项目，有人在一段时间后就开始了。它是用DevExpress for Winforms制作的。他已准备好“欢迎”页面，带有“welkom”标签和“ik heb een afspraak”标签（3个底部标签的顶部）。我刚刚开始研究它，似乎无法找出为什么我启动程序/ winforms时我新添加的Labelcontrols（2个底部的）没有出现。

以下是设计师的外观图像：

这是Designer代码页（Designer.cs文件）：

    partial class Welcome
    {
        /// <summary>
        /// Required designer variable.
        /// </summary>
        private System.ComponentModel.IContainer components = null;

        /// <summary>
        /// Clean up any resources being used.
        /// </summary>
        /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);
        }

我不熟悉DevExpress，所以也许我忘记了某个地方？

我不熟悉DevExpress所以也许我忘记了什么某处？

我相信你没有忘记任何事情，因为设计师已经看到了新的标签。这个谜语必须有一个非常简单的钥匙。

在Welcome_Load方法中注释掉这一行：

 _controller.LoadLayout(layoutCtrlMain, Enums.LayoutType.Welcome);

如果这有帮助，则不会显示新添加的标签，因为先前保存的布局不包含它们。

要解决此问题并保持_controller.LoadLayout代码行取消注释，请找到_controller保存布局的文件并将其删除。
