WPF 小知识点001

1.DataGrid 单选事件

<DataGrid MinHeight="150"
                  AutoGenerateColumns="False"
                  CanUserAddRows="False"
                  IsReadOnly="True"
                  ItemsSource="{Binding DBG_ReserveData}"
                  SelectedItem="{Binding TCmsReserveNet}"
                  SelectionMode="Single">

<!-- *** -->

</DataGrid>

下面文本框中上一级菜单绑定DataSource 或者DataContent 绑定TCmsReserveNet,文本框绑定到里面的属性;

2.不用SelectedItem

<i:Interaction.Triggers>
                <i:EventTrigger EventName="SelectionChanged">
                    <i:InvokeCommandAction Command="{Binding SelectedCmsReserveCommand}" />
                </i:EventTrigger>
            </i:Interaction.Triggers>

SelectedCmsReserveCommand:

  public ICommand SelectedCmsReserveCommand
        {
            get
            {
                return new RelayCommand<string>(parameter =>
                {
                    if (DBG_ReserveData.CurrentItem != null)
                    {
                        //获取当前选中列
                        t_cms_reserveNet seCmsReserveNet = (t_cms_reserveNet)DBG_ReserveData.CurrentItem;

                        fGuestName = seCmsReserveNet.GN;
                        fBeginTime = seCmsReserveNet.BT;
                        fEndTime = seCmsReserveNet.ET;
                        fPhone = seCmsReserveNet.P;
                        fManagerID = seCmsReserveNet.MID;

                        fMoneyState = seCmsReserveNet.MS;
                        fNote = seCmsReserveNet.N;
                        fReserveState = seCmsReserveNet.RS;
                        fRoomTypeID = seCmsReserveNet.RTID;
                        fRoomID = seCmsReserveNet.FRID;

                        fSubscription = seCmsReserveNet.ST;
                        mTCmsReserve.fReserveID = seCmsReserveNet.RID;
                    }
                });
            }
        }
