Xaml 对行和列进行绑定的DataGrid？

其他块的特性显示在其他列中。例如，复选框、重复项、名称为IsSelected
public interface ISymbol
{
int Index { get; set; }
bool ReadOnly { get; set; }
string SymbolText { get; set; }
}
public class BlockBase : ObservableObject, IDataErrorInfo
{
public bool IsSelected
{
get { return _isSelected; }
set
{
if (value == _isSelected)
return;
_isSelected = value;
OnPropertyChanged("IsSelected");
RaiseSelectionChangedEvent();
}
}
public string Name { get; set; }
public virtual BindingList<ISymbol> Symbols { get; set; }

}

set
{
// … validate and set _binSymbol & _hexSymbol values

我试图在DataGrid.Resources中将其定义为CellPermissionStyle，但我不知道如何访问此级别的符号 此外，最好用模板替换符号的所有重复DataGridTextColumn防御
有人能帮我吗？我的研究刚刚证实，不幸的是，对于适用于列子集的模板或样式，无法做到这一点。正如米什卡所建议的那样，向样式或模板发送参数也是不可能的：（ 因此，我的16列中的每一列都使用了“复制粘贴修改”单元格样式，如下所示：
<DataGridTextColumn Header="[0]" Binding="{Binding .Symbols[0].SymbolText, UpdateSourceTrigger=LostFocus}">
<DataGridTextColumn.CellStyle>
<Style TargetType="DataGridCell">
<Setter Property="Background" Value="{Binding .Symbols[0].ReadOnly, Converter={StaticResource SymbolReadOnlyToBrushConverter}}" />
<Setter Property="IsEnabled" Value="{Binding .Symbols[0].ReadOnly, Converter={StaticResource SymbolReadOnlyToEnabledConverter}}" />
<Setter Property="TextBlock.TextAlignment" Value="Center" />
</Style>
</DataGridTextColumn.CellStyle>
</DataGridTextColumn>
如果有人能建议在XAML中使用更好、更优雅的方法，我会很高兴。您能从您的XAML中显示整个数据网格，以及块定义代码吗？@Mishka，我已经用您要求的信息编辑了我的问题。谢谢您的单元格样式，它当前绑定到许可，而不是只读。我想，既然您使用了Convery无论如何，你可以绑定到“empty”，意思是块，然后在转换器中得到它的符号
<DataGridTextColumn Header="[15]" Binding="{Binding .Symbols[15].SymbolText, UpdateSourceTrigger=LostFocus}">
<DataGridTextColumn.CellStyle>
<Style TargetType="DataGridCell">
<Setter Property="Background" Value="{Binding .Symbols[15].ReadOnly, Converter={StaticResource SymbolReadOnlyToBrushConverter}}" />
<Setter Property="IsEnabled" Value="{Binding .Symbols[15].ReadOnly, Converter={StaticResource SymbolReadOnlyToEnabledConverter}}" />
<Setter Property="TextBlock.TextAlignment" Value="Center" />
</Style>
</DataGridTextColumn.CellStyle>
