在DataGrid单元格中添加一个小的彩色矩形

Question

我期待在我的DataGrid中添加一个细小的（10x10）矩形作为单元格。我已经把它设置在对象中，我只是想找到一种方法将它从代码中提取到我的DataGrid中。

这是我的DataGrid XAML：

<DataGrid Name="dataGrid1" Grid.Row="2" AutoGenerateColumns="False" DataContext="{Binding}" HeadersVisibility="Column" 
       HorizontalGridLinesBrush="#ccc" VerticalGridLinesBrush="#ccc" VirtualizingStackPanel.VirtualizationMode="Standard" Background="#FFF6F6F6" CanUserAddRows="False"> 
     <DataGrid.Resources> 
      <ResourceDictionary Source="Pages/DataGridStyle.xaml" /> 
     </DataGrid.Resources> 
     <DataGrid.Columns> 
      <!-- In here I would like a datagrid cell that is just a 10x10 box which uses {Binding Path=TemplateCellColour} (templatecellcolour is stored as a brush, is this an issue? --> 
      <DataGridTextColumn ElementStyle="{StaticResource CenterTextCell}" Width="0.5*" Binding="{Binding Path=TemplateCellID}" Header="ID"></DataGridTextColumn> 
      <DataGridTextColumn ElementStyle="{StaticResource CenterTextCell}" Width="1*" Binding="{Binding Path=CellWidth}" Header="Width"></DataGridTextColumn> 
      <DataGridTextColumn ElementStyle="{StaticResource CenterTextCell}" Width="1*" Binding="{Binding Path=CellHeight}" Header="Height"></DataGridTextColumn> 
      <DataGridTextColumn ElementStyle="{StaticResource CenterTextCell}" Width="1*" Binding="{Binding Path=CellTop}" Header="Top"></DataGridTextColumn> 
      <DataGridTextColumn ElementStyle="{StaticResource CenterTextCell}" Width="1*" Binding="{Binding Path=CellLeft}" Header="Left"></DataGridTextColumn> 
     </DataGrid.Columns> 
</DataGrid> 

请参阅意见，我想要的东西更容易理解。

Answer 1

将DataGridTextColumn替换为DataGridTemplateColumn。事情是这样的：

<DataGridTemplateColumn > 
    <DataGridTemplateColumn.CellTemplate> 
     <DataTemplate> 
      <Rectangle Width="10" Height="10" Fill="{Binding TemplateCellColour}" /> 
     </DataTemplate> 
    </DataGridTemplateColumn.CellTemplate> 
</DataGridTemplateColumn> 

是的，TemplateCellColour应该是一个Brush，这是正确的。
