wpf, 根据绑定的属性的值的不同(数据分类)，界面上显示不同的控件(绑定不同类型的属性),可以使用数据库触发器DataTrigger实现这一功能。

实现的效果如下：

 

首先建立实体类：

更改通知类：

public class NotifyPropertyChangedObject : INotifyPropertyChanged    {        /// 
        /// 属性更改事件        /// 
        public event PropertyChangedEventHandler PropertyChanged;        /// 
        /// 触发属性更改事件        /// 
        /// 属性名称        protected virtual void OnPropertyChanged(string propertyName)        {            PropertyChangedEventHandler propertyChanged = this.PropertyChanged;            if (propertyChanged != null)            {                propertyChanged(this, new PropertyChangedEventArgs(propertyName));            }        }    }

检查定义类：

public class CheckDefine:NotifyPropertyChangedObject    {        #region Model        private Guid _checkDefineId;        private int _seqno;        private string _checkitem;        private int _checktype;        /// 
        /// 主键id        /// 
        public Guid CheckDefineId        {            set            {                _checkDefineId = value;                OnPropertyChanged("CheckDefineId");            }            get { return _checkDefineId; }        }              /// 
        /// 编号        /// 
        public int SeqNo        {            set            {                _seqno = value;                OnPropertyChanged("SeqNo");            }            get { return _seqno; }        }        /// 
        /// 检查项        /// 
        public string CheckItem        {            set            {                _checkitem = value;                OnPropertyChanged("CheckItem");            }            get { return _checkitem; }        }        /// 
        /// 1:bool ;2:text;3:Numeric        /// 
        public int CheckType        {            set            {                _checktype = value;                OnPropertyChanged("CheckType");            }            get { return _checktype; }        }                #endregion Model    }

检查记录类：

public class CheckRecord : NotifyPropertyChangedObject    {        #region Model        private CheckDefine _checkCheckDefine;        private Guid _checkid;        private bool? _resultbool;        private string _resulttext;        private decimal? _resultnumeric;        private Guid _userid1;        private Guid _userid2;        private DateTime? _operatingdt;        /// 
        /// 生产前的检查(定义)        /// 
        public CheckDefine CheckDefine        {            set            {                _checkCheckDefine = value;                OnPropertyChanged("CheckDefine");            }            get { return _checkCheckDefine; }        }        /// 
        /// 主键id        /// 
        public Guid CheckId        {            set            {                _checkid = value;                OnPropertyChanged("CheckBeforeProductionRecordid");            }            get { return _checkid; }        }        /// 
        /// 勾选框        /// 
        public bool? ResultBool        {            set            {                _resultbool = value;                OnPropertyChanged("ResultBool");            }            get { return _resultbool; }        }        /// 
        /// 文本输入框        /// 
        public string ResultText        {            set            {                _resulttext = value;                OnPropertyChanged("ResultText");            }            get { return _resulttext; }        }        /// 
        /// 数字类型(输入框)        /// 
        public decimal? ResultNumeric        {            set            {                _resultnumeric = value;                OnPropertyChanged("ResultNumeric");            }            get { return _resultnumeric; }        }        /// 
        /// 操作人        /// 
        public Guid Userid1        {            set            {                _userid1 = value;                OnPropertyChanged("Userid1");            }            get { return _userid1; }        }        /// 
        /// 复核人        /// 
        public Guid Userid2        {            set            {                _userid2 = value;                OnPropertyChanged("Userid2");            }            get { return _userid2; }        }        /// 
        /// 检查时间        /// 
        public DateTime? Operatingdt        {            set            {                _operatingdt = value;                OnPropertyChanged("Operatingdt");            }            get { return _operatingdt; }        }        #endregion Model    }

 

xaml:

 

注：

    从xaml中可知：ListView的ItemsSource绑定了CheckRecords集合，

ListView的第二列的CellTemplate里是一Grid里有两个TextBox和一个CheckBox控件，

三个控件分别绑定到了CheckRecord类的三个不同类型的属性，且三个控件都默认是不可见的。

 

在DataTemplate.Triggers中绑定了三个DataTrigger，且都绑定到了CheckDefine.CheckType这个属性，

从而根据CheckDefine.CheckType的值来决定三个控件中哪个控件可见(Visibility="Visible")
