It's hard to say without knowing specifics, but here's a DataGridTextColumnthat is centered:

在不知道具体情况的情况下很难说，但这里有一个DataGridTextColumn集中的：

<wpf:DataGridTextColumn Header="Name" Binding="{Binding Name}" IsReadOnly="True">
    <wpf:DataGridTextColumn.CellStyle>
        <Style>
            <Setter Property="FrameworkElement.HorizontalAlignment" Value="Center"/>
        </Style>
    </wpf:DataGridTextColumn.CellStyle>
</wpf:DataGridTextColumn>

Ok, I used the frameworkElement approach but there was a strange behavior when you try to highlight the row.

好的，我使用了 frameworkElement 方法，但是当您尝试突出显示行时出现了奇怪的行为。

I've put another example of WPF Datagrid alignment in this thread!

我在这个线程中放了另一个 WPF Datagrid 对齐的例子！

If you are using DataGridTextColumn you can use the following code snippet:

如果您使用的是 DataGridTextColumn，则可以使用以下代码片段：

<Style TargetType="DataGridCell">
     <Style.Setters>
            <Setter Property="TextBlock.TextAlignment" Value="Center" />
     </Style.Setters>
</Style>

+1 for Kent Boogaart. I ended up doing this, which makes the code slightly less cluttered (and enables me to use the alignment on several columns):

+1 为肯特·布加特。我最终这样做了，这使代码稍微不那么混乱（并使我能够在多列上使用对齐方式）：

<Resources>
      <Style x:Key="NameCellStyle" TargetType="DataGridCell">
                <Setter Property="HorizontalAlignment" Value="Center" />
      </Style>
</Resources>


<DataGrid.Columns>                           
   <DataGridTextColumn Header="Name" CellStyle="{StaticResource NameCellStyle}" Binding="{Binding Name}"/>                            
    // .. other columns        
</DataGrid.Columns>

My favorite solution is:

我最喜欢的解决方案是：

<DataGridTextColumn Header="My Column" Binding="{Binding MyDBValue}" Width="100" >
<DataGridTextColumn.CellStyle>
        <Style>
                <Setter Property="FrameworkElement.HorizontalAlignment" Value="Center"/>
        </Style>
</DataGridTextColumn.CellStyle>

Or in code behind:

或者在后面的代码中：

grid.CellStyle = newCellStyle();

public static Style newCellStyle()
{
    //And here is the C# code to achieve the above
    System.Windows.Style style = new Style(typeof(DataGridCell));
    style.Setters.Add(new System.Windows.Setter
    {
        Property = Control.HorizontalAlignmentProperty,
        Value = HorizontalAlignment.Center
    });
    return style;
}

I started with huttelihut's solution. Unfortunately, that didn't work for me just yet. I tweaked his answer and came up with this (solution is to align the text to the right):

我从 httelihut 的解决方案开始。不幸的是，这对我来说还行不通。我调整了他的答案并想出了这个（解决方案是将文本向右对齐）：

<Resources>
    <Style x:Key="RightAligned" TargetType="TextBlock">
        <Setter Property="HorizontalAlignment" Value="Right"/>
    </Style>
</Resources>

As you can see, I applied the style to a TextBlock, not the DataGridCell.

如您所见，我将样式应用于 TextBlock，而不是 DataGridCell。

And then I had to set the Elementstyle, not the Cellstyle.

然后我必须设置元素样式，而不是单元样式。

ElementStyle="{StaticResource RightAligned}"

I ended up having problems with the cell being shifted and looking funky using the accepted answer. I know it's late, but hopefully my findings will help someone. I use:

我最终遇到了问题，使用已接受的答案将单元格移动并看起来很时髦。我知道已经晚了，但希望我的发现会对某人有所帮助。我用：

<DataGridTextColumn.ElementStyle>
     <Style>
          <Setter Property="FrameworkElement.HorizontalAlignment" Value="Center"/>
     </Style>

rather than the CellStyle.

而不是 CellStyle。

Here's @MohammedAFadil's XAML answer, converted to C# code behind:

这是@MohammedAFadil 的 XAML 答案，转换为后面的 C# 代码：

var MyStyle = new Style(typeof(DataGridCell)) {
    Setters = {
        new Setter(TextBlock.TextAlignmentProperty, TextAlignment.Center)
    }
};

To apply the Style, set the CellStyleproperty of the DataGrid, e.g.

要应用Style，请设置 的CellStyle属性DataGrid，例如

var MyGrid = new DataGrid() {
    CellStyle = MyStyle
};

Thanks Danny Beckett for converting @MohammedAFadil's XAML answer, converted to C# code. All of my datagrids are set up dynamically, so I can change anything, whenever.

感谢 Danny Beckett 将 @MohammedAFadil 的 XAML 答案转换为 C# 代码。我所有的数据网格都是动态设置的，因此我可以随时更改任何内容。

To set up an empty datagrid, with nothing in it and then just bind it to data, just take your datagrid.columns

要设置一个空的数据网格，其中没有任何内容，然后将其绑定到数据，只需获取 datagrid.columns

        var centerTextSetter = new Style(typeof(DataGridCell))
        {
            Setters = { new Setter(TextBlock.TextAlignmentProperty, TextAlignment.Center) }
        };
        DgDbNames.Columns.Add(new DataGridTextColumn()
        {
            Header = "Db Name",
            Binding = new System.Windows.Data.Binding("DbName"),
            IsReadOnly = true,
            Width = new DataGridLength(0.2, DataGridLengthUnitType.Star),
            CellStyle = centerTextSetter
        });
