WinForm 动态设置控件属性

本文用到的是 Winform + Dev 控件

主要功能：可以读取配置（从数据库或者配置文件中读取），通过配置控制前面控件的属性

• 放点控件

• 先准备用到的实体

/// <summary>
/// 控件配置
/// </summary>
public class ControlList
{
    /// <summary>
    /// 控件NAME
    /// </summary>
    public string ControlName { get; set; }
    /// <summary>
    /// 控件类型
    /// </summary>
    public string ControlTypeName { get; set; }
    /// <summary>
    /// 控件默认值
    /// </summary>
    public string ControlDefaultVal { get; set; }
    /// <summary>
    /// 控件可用
    /// </summary>
    public bool ControlEnable { get; set; }
    /// <summary>
    /// 控件显示
    /// </summary>
    public ControlvisibleInfo ControlVisible { get; set; }
}

public class ControlvisibleInfo
{
    /// <summary>
    /// 显示值 
    /// </summary>
    public DevExpress.XtraLayout.Utils.LayoutVisibility IsVisible { get; set; }

    /// <summary>
    /// 包控件的Item
    /// </summary>
    public string PatientItem { get; set; }
}
