如何改变自定义控件中包含的某个子控件属性？

Question

准备设计一个自定义控件，实现选择保存文件路径，包含有自定义路径和默认路径，其中控件有：GroupPanel一个、LabelX一个、TextBoxX一个、RadioButton两个、ButtonX按钮一个，我想动态改变Lebel的Text属性以及GroupPanel的背景、样式等等，在将该自定义控件加载到一窗体后，找到对应的子控件属性，改变相应值，保存窗体，然后关闭窗体后再重新打开窗体，发现该刚才在控件上修改的子控件属性又恢复到默认值。不知道该如何实现我需要的功能。谢谢指教！

Answer 1

举个例子
比如你想改变Labelx的Text属性，不必将整个控件公开吧，只要添加一个访问LabelX.Text的属性就可以啊
[Category("自定义参数设置")]
        [Description("获取/设置控件标题提示语控件")]
        public LabelX Control_LableTitle
        {
            get
            {
                return this.m_ctrlLabel_SavePathTitle;
            }
            set
            {
                this.m_ctrlLabel_SavePathTitle = value;
                this.lblSavePathTitle.Text = value.Text;
                this.lblSavePathTitle.Font = value.Font;
                this.lblSavePathTitle.ForeColor = value.ForeColor;
            }
        }
可以换成
[Category("自定义参数设置")]
        [Description("获取/设置控件标题提示语控件")]
        public string Control_LableTitle
        {
            get
            {
                return this.m_ctrlLabel_SavePathTitle.Text;
            }
            set
            {
                this.lblSavePathTitle.Text = value                            }
        }如果还不行就将setter方法的那句代码改作用propertyinfo.Setvalue的方法更改控件在设计阶段的更改

Answer 2

因为我可能不仅仅对控件的这几个属性进行修改，所以就想将整个子控件全部暴露，针对你说的“setter方法的那句代码改作用propertyinfo.Setvalue的方法更改控件在设计阶段的更改”，该如何用？没用过。

Answer 3

用是用propetyinfo pi=this.gettype().getproperty("<属性名>").setvalue(this,value);
不记得这样写对不对，这样在设计阶段设计器可接收到属性的更改事件，进而生成设计时的必要代码，这样才能将设计时的更改带到运行时呀！

Answer 4

既然你想“将整个子控件全部暴露”，那么就应该这样实现，举例如下：
[Category("自定义参数设置")]
[Description("获取/设置控件标题提示语控件")]
public LabelX Control_LableTitle
{
    get
    {
       return this.lblSavePathTitle;
    }
}
直接获取引用对象，这样它内部的属性就全部暴露了，但是绝对不能设置set属性。原因？你自己先想想。

Answer 5

按你的想法，如果要完全公开，那么直接public那个控件就成了
