dxg:GridControl

dxg:TableView

WPF项目

Visual Studio

1. 前端代码

前端有两种方法，一种是GridControl的CurrentItem属性，一种是TableView的FocusedRow属性，二选一即可

示例：

xml 复制代码

<dxg:GridControl CurrentItem="{Binding CurrentLogInfo,Mode=TwoWay}">
                <dxg:GridControl.View>
                    <dxg:TableView AllowEditing="False" FocusedRow="{Binding CurrentLogInfo,Mode=TwoWay}"/>
                </dxg:GridControl.View>
                <dxg:GridControl.Columns>
                </dxg:GridControl.Columns>
            </dxg:GridControl>

2. 后端代码

继承INotifyPropertyChanged并实现RaisePropertyChanged

csharp 复制代码

public class LogViewModel : INotifyPropertyChanged
    {
        public ObservableCollection<LogInfo> logList { get; set; }
        private object _syncLock = new Object();
        public ICollectionView CollectionView { get; set; }

        public LogInfo CurrentLogInfo
        {
            get
            {
                return _currentLogInfo;
            }

            set
            {
                _currentLogInfo = value;
                RaisePropertyChanged("CurrentLogInfo");
            }
        }
        LogInfo _currentLogInfo;
        public event PropertyChangedEventHandler PropertyChanged;
        private void RaisePropertyChanged(String propertyName)
        {
            if (PropertyChanged != null)
            {
                PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
            }
        }

        public LogViewModel()
        {
            logList = new ObservableCollection<LogInfo>();

            CollectionView = CollectionViewSource.GetDefaultView(logList);
            BindingOperations.EnableCollectionSynchronization(logList, _syncLock);
        }
    }

这样我们在改变CurrentLogInfo时，就会通知客户端属性值已更改。

csharp 复制代码

logvm.logList.Add(log);
logvm.CurrentLogInfo = log;
