我有一个用于两个不同视图的DataGrid.在每种情况下,如果用户调整主机控件/视图的大小,我都希望最后一列的大小为其宽度.

你会怎么做？

    <DataGrid.Columns>
        <DataGridTextColumn 
            Header="Number" Binding="{Binding BusinessId}" IsReadOnly="True" 
            CanUserSort="True" CanUserResize="False"
            Width="75"/>
        <DataGridTextColumn 
            Header="Description" Binding="{Binding Description}" IsReadOnly="True" 
            CanUserSort="True" SortDirection="Ascending" CanUserResize="True"
            MinWidth="260" Width="Auto"  />
    </DataGrid.Columns>

</DataGrid>

UPDATE(工作代码)

我只是在xaml中命名该列,然后将以下代码放入代码隐藏中.如果有人有更好的主意或优化方法,请告诉我！

public partial class Listing : UserControl
{
    private double _currentColumnWidth;

    public Listing()
    {
        InitializeComponent();

        Loaded += onl oaded;
        SizeChanged += OnSizeChanged;
    }

    private void onl oaded(object sender, RoutedEventArgs e)
    {
        _currentColumnWidth = colDescription.ActualWidth;
    }

    private void OnSizeChanged(object sender, SizeChangedEventArgs e)
    {
        // split if control is not loaded yet
        if (_currentColumnWidth == 0) return;

        // only interested in width, not height
        var widthChanged = e.WidthChanged;
        if (!widthChanged) return;

        var delta = e.NewSize.Width - e.PreviousSize.Width;
        var newWidth = _currentColumnWidth + delta;
        if (newWidth <= colDescription.MinWidth || newWidth >= colDescription.MaxWidth) return;

        _currentColumnWidth = newWidth;
        colDescription.Width = new DataGridLength(_currentColumnWidth);
    }
}

解决方法:

简单,只需替换XAML中的width属性

<DataGridTextColumn 
                Header="Description" Binding="{Binding Description}" 
                IsReadOnly="True" 
                CanUserSort="True" SortDirection="Ascending" CanUserResize="True"
                MinWidth="260" Width="Auto"  />

至 …

<DataGridTextColumn 
                Header="Description" Binding="{Binding Description}" IsReadOnly="True" 
                CanUserSort="True" SortDirection="Ascending" CanUserResize="True"
                MinWidth="260" Width="*"  />

您不需要任何代码来进行宽度的处理,因为WPF可以在XAML中满足此要求.

“ *”表示自动尺寸值：)
