DevExpress Winforms：为什么我的新添加的Labelcontrols不会出现？
问题描述 投票：0回答：1
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。
这是设计师看起来的形象：
这是Designer代码页（Designer.cs文件）：
partial class Welcome

/// </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);
}
#region Windows Form Designer generated code

/// the contents of this method with the code editor.

我不熟悉DevExpress，所以也许我忘了某个地方的东西？

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关键。
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。
