[Bindable(false), Category("Appearance"), DefaultValue("")]
        #region Enable
        public override bool Enabled
        {
            get
            {
                //生成时没错误,但把控件拖到aspx界面时会出错.
                return this.Enabled;
            }
            set
            {
                //生成时没错误,但把控件拖到aspx界面时会出错.
                this.Enabled = value;

Answer 1

public override bool Enabled
{
get
{
return base.Enabled;
}
set
{
base.Enabled = value;
}
}

Answer 2

public override bool Enabled
        {
            get
            {
                //生成时没错误,但把控件拖到aspx界面时会出错.
                return this.Enabled;//这里会无穷递归 ，不出错才怪
