格式化数据绑定DataGrid的显示属性

Question

我有DataGrid通过数据绑定显示其行和列。我的问题是，如何清理DataGrid的显示？例如，通过设置列width来消除未使用的空间。通常我会为每个width设置DataGridTextColumn，但这次我甚至不需要在XAML中使用该行（而且它也不起作用，因为我＆＃39} ; m使用数据绑定填充。）

我的DataGrid正在使用中（查看右侧的所有多余空间？）：

DataGrid的XAML：

<DataGrid AutoGenerateColumns="False" ItemsSource="{Binding TransInfoCollection}" IsReadOnly="True" SelectedItem="{Binding SelectedTransponder}" Margin="12,12,14,60" CanUserResizeColumns="False" CanUserResizeRows="True" >
        <DataGrid.Columns>
            <DataGridTextColumn Header="{DynamicResource transLocation}" Binding="{Binding Path=Location}" Width="90" />
            <DataGridTextColumn Header="{DynamicResource transponder}" Binding="{Binding Path=Tranponder}" Width="*" />
        </DataGrid.Columns>
    </DataGrid>

窗口的ViewModel：

public class TransponderMaintenanceViewModel : PropertyChangedBase
{
    private ObservableCollection<TransponderProps> _transInfoCollection; //DataGrid Collection
    private TransponderProps _selectedTransponder;

    private Command _deleteCommand;

    HierarchicalVM pathLocationsNode = App.MainTree.Data[2].Children[0]; //Path -> Locations

    public TransponderMaintenanceViewModel()
    {
        TransInfoCollection = new ObservableCollection<TransponderProps>();

        _deleteCommand = new Command(DeleteCommand_Ops);

        for (int i = 0; i < pathLocationsNode.Children.Count(); i++) //Adds Transponder information to DataGrid
        {
            if (pathLocationsNode.Children[i].Children[0].Children.Count() > 0)
            {
                for (int j = 0; j < pathLocationsNode.Children[i].Children[0].Children.Count(); j++)
                {
                    TransInfoCollection.Add(new TransponderProps { Location = new MultiItemString(new[] { Regex.Match(pathLocationsNode.Children[i].DisplayName.Value, @"\d+").Value }, false), 
                        Transponder = new MultiItemString(new[] { pathLocationsNode.Children[i].Children[0].Children[j].DisplayName.Value }, false) });
                }
            }
        }
    }

    //Prop for Collection that will store Transponders and their Location
    public ObservableCollection<TransponderProps> TransInfoCollection
    {
        get { return _transInfoCollection; }
        set
        {
            _transInfoCollection = value;
            NotifyPropertyChange(() => TransInfoCollection);
        }
    }

    //Prop for the SelectedItem in the DataGrid
    public TransponderProps SelectedTransponder
    {
        get { return _selectedTransponder; }
        set
        {
            _selectedTransponder = value;
            NotifyPropertyChange(() => SelectedTransponder);
        }
    }

    //Delete Command
    public Command DeleteCommand { get { return _deleteCommand; } }
    private void DeleteCommand_Ops()
    {
        for (int i = 0; i < pathLocationsNode.Children.Count(); i++) //Delete Transponder from CartTools
        {
            for (int j = 0; j < pathLocationsNode.Children[i].Children[0].Children.Count(); j++)
            {
                if (pathLocationsNode.Children[i].Children[0].Children[j].DisplayName.Value == SelectedTransponder.Transponder.Value)
                {
                    var transParent = pathLocationsNode.Children[i].Children[0];
                    transParent.Children.Remove(transParent.Children[j]);
                }
            }
        }

        TransInfoCollection.Remove(SelectedTransponder); //Remove Transponder from DataGrid
    }
}

public class TransponderProps : PropertyChangedBase
{
    private MultiItemString _location, _transponder;

    public TransponderProps()
    {

    }

    public MultiItemString Location
    {
        get { return _location; }
        set
        {
            _location = value;
            NotifyPropertyChange(() => Location);
        }
    }
    public MultiItemString Transponder
    {
        get { return _transponder; }
        set
        {
            _transponder = value;
            NotifyPropertyChange(() => Transponder);
        }
    }
}

如果您不自动生成列，则可以控制每列的​​许多属性。如果您使用width = "*"，则它是一张外卡，将占用剩余的空间。

<DataGrid AutoGenerateColumns="False" ItemsSource="{Binding TransInfoCollection}" IsReadOnly="True" SelectedItem="{Binding SelectedTransponder}" Margin="12,12,14,60" CanUserResizeColumns="False" CanUserResizeRows="True"  >
    <DataGrid.Columns>
                <DataGridTextColumn Binding="{Binding Path=Location}" Header="Location" Width="90" />
                <DataGridTextColumn Binding="{Binding Path=Transponder}" Header="Transponder" Width="*" />                           
     </DataGrid.Columns>       
</DataGrid>
