动态刷新Colume4的值
1:原数据定义
数据类继承：INotifyPropertyChanged, 实现INotifyPropertyChanged接口
public class CustomTableColumes: INotifyPropertyChanged
{
public event PropertyChangedEventHandler PropertyChanged;
public void NotiFy(string property)
{
if (PropertyChanged != null)
{
PropertyChanged(this, new PropertyChangedEventArgs(property));
}
}
//实时刷新行里的某一列调用NotiFy
public string Colume4
{
get
{
return _Colume4;
}
set
{
_Colume4 = value;
NotiFy("Colume4");
}
}
2:ModeView 定义ObservableCollection
public class PlcDebugViewModel : GenericViewModel<XmlItemNew>
{
private ObservableCollection<CustomTableColumes> customTable = new ObservableCollection<CustomTableColumes>();
public ObservableCollection<CustomTableColumes> CustomTable
{
get
{
return customTable;
}
set
{
this.customTable = value;
this.RaisePropertyChanged(() => this.CustomTable);
}
}
}
3:View 绑定数据源xaml
<DataGrid Name="Mygrid" Grid.Row="2" Grid.Column="1" Grid.RowSpan="24" Margin="5" SelectedCellsChanged="DataRowSelected" ItemsSource="{Binding CustomTable}" >
<DataGrid.Columns>
<DataGridTextColumn Width="130*" Header="名称" Binding="{Binding Colume0}" IsReadOnly="True"/>
<DataGridTextColumn Width="60*" Header="读写属性" Binding="{Binding Colume1}" IsReadOnly="True"/>
<DataGridTextColumn Width="90*" Header="数值范围" Binding="{Binding Colume2}" IsReadOnly="True"/>
<DataGridTextColumn Width="100*" Header="内控参数" Binding="{Binding Colume3}" IsReadOnly="True"/>
<DataGridTextColumn Width="100*" Header="当前内容" Binding="{Binding Colume4}" IsReadOnly="True"/>
<DataGridTextColumn Width="195*" Header="备注说明" Binding="{Binding Colume5}" IsReadOnly="True"/>
<DataGridTextColumn Width="30*" Header="" Visibility="Hidden" Binding="{Binding Colume6}" IsReadOnly="True"/>
<DataGridTextColumn Width="30*" Header="" Visibility="Hidden" Binding="{Binding Colume7}" IsReadOnly="True"/>
</DataGrid.Columns>
</DataGrid>
