我把我的单元格包装起来有些麻烦，它们只是走出界限，当我看到可视树时我可以看到在contentpresenter里面它看到了一个文本块，我尝试在内容上设置一个样式演示者，但是当我看到属性时，它说没有包装。
我不知道如何使用数据模板，使其成为绑定到gridview的expando对象列表，其中动态属性由列名绑定。所以我不知道如何绑定text =“{dynamic dynamicproperty}。因此我试图在内容演示者上更改它。

<DataGrid HeadersVisibility="None"
ItemsSource="{Binding SheetData}"
Background="Transparent"
AutoGenerateColumns="False"
ColumnWidth="*"

BorderBrush="White"

编辑： 因为我不认为我能够在其中使用带有TextBlock的DataTemplate，由于我绑定列的方式，从我的附加行为，也许有一种方法可以从代码中添加Text包装。我使用了来自here的附加行为。
这是我的附加行为：
public class GridViewBindingBehavior
{
public static readonly DependencyProperty ColumnsCollectionProperty = DependencyProperty.RegisterAttached("ColumnsCollection", typeof(ObservableCollection<DataGridColumns>), typeof(GridViewBindingBehavior), new PropertyMetadata(OnColumnsCollectionChanged));
public static void SetColumnsCollection(DependencyObject o, ObservableCollection<ColumnDefinition> value)
{
o.SetValue(ColumnsCollectionProperty, value);
}
public static ObservableCollection<ColumnDefinition> GetColumnsCollection(DependencyObject o)
{
return o.GetValue(ColumnsCollectionProperty) as ObservableCollection<ColumnDefinition>;
}
private static void OnColumnsCollectionChanged(DependencyObject o, DependencyPropertyChangedEventArgs e)
{
DataGrid gridView = o as DataGrid;
if (gridView == null)
{
return;
}
gridView.Columns.Clear();
if (gridView.ItemsSource == null)
{
return;
}
ObservableCollection<ExpandoObject> objExpando = (ObservableCollection<ExpandoObject>)gridView.ItemsSource;
if (e.NewValue == null)
{
return;
}
var collection = e.NewValue as ObservableCollection<DataGridColumns>;
if (collection == null)
{
return;
}
foreach (var column in collection)
{
var gridViewColumn = GetDataColumn(column);
gridView.Columns.Add(gridViewColumn);
}
}
private static DataGridTextColumn GetDataColumn(DataGridColumns columnName)
{
var column = new DataGridTextColumn();
column.IsReadOnly = true;
column.Header = columnName.DisplayColumnName;
Binding binding = new Binding();
binding.Converter = new ColumnValueConverter();
binding.ConverterParameter = columnName.BindingPropertyName;
column.Binding = binding;
return column;
}
}
编辑2：
我设法让它与价值转换器一起使用。唯一的问题是他们找到我所在的实际行是如此丑陋，是否有办法将datagrid绑定到第二个绑定。我看到datagrid有CurrentColumn属性，但我认为这是用于选择，并且在转换器内部时为null。
更新了datagrid：
<DataGrid HeadersVisibility="None"
ItemsSource="{Binding SheetData}"
Background="Transparent"
AutoGenerateColumns="False"
ColumnWidth="*"
BorderThickness="0,2,0,0"
UseLayoutRounding="True"
BorderBrush="White"
RowBackground="Transparent"
MaxWidth="700"
ScrollViewer.HorizontalScrollBarVisibility="Disabled"
HorizontalGridLinesBrush="White"
VerticalGridLinesBrush="White"
Behaviors:GridViewBindingBehavior.ColumnsCollection="{Binding ColumnData}"
VerticalAlignment="Top"
HorizontalContentAlignment="Left"
Width="auto">
<DataGrid.RowHeaderTemplate>
<DataTemplate>
<TextBlock Margin="5,0" Text="{Binding RelativeSource={RelativeSource Mode=FindAncestor,
AncestorType={x:Type DataGridRow}},
Path=Item.RowIndex}"/>
</DataTemplate>
</DataGrid.RowHeaderTemplate>
<DataGrid.CellStyle>
<Style TargetType="DataGridCell">
<Setter Property="Padding" Value="8, 7"/>
<Setter Property="BorderThickness" Value="2" />
<Setter Property="BorderBrush" Value="White" />
<Setter Property="Background" Value="#f1f2f4" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type DataGridCell}">
<Border Padding="{TemplateBinding Padding}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" SnapsToDevicePixels="True">
<TextBlock TextWrapping="WrapWithOverflow" >
<TextBlock.Text>
<MultiBinding Converter="{StaticResource columnConver}">
<Binding Path="." />
<Binding RelativeSource="{RelativeSource Mode=FindAncestor, AncestorType={x:Type DataGrid}}" Path="." />
</MultiBinding>
</TextBlock.Text>
</TextBlock>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</DataGrid.CellStyle>
</DataGrid>
丑陋的价值转换器：
public class ColumnMultiValueConverter : IMultiValueConverter
{
private static int columnIndex = 0;
private static int lastCount = 0;
public object Convert(object[] values, Type targetType, object parameter, CultureInfo culture)
{
var row = values[0] as IDictionary<string, object>;
if (row == null)
return row;
var datagrid = values[1] as DataGrid;
if (columnIndex >= datagrid.Columns.Count || lastCount != datagrid.Columns.Count)
columnIndex = 0;
var result = (row[datagrid.Columns[columnIndex].Header.ToString()]);
columnIndex++;
lastCount = datagrid.Columns.Count;
return (result as GridCell)?.Value?.ToString();
}
这可能需要成为一个新的问题，因为包装完成了。 只是我的代码变得非常难看。
