DataGrid row content vertical alignment

问题

I have a regular DataGrid from WPF 4.0 RTM, where I put data from a database. In order to make clean & light style of DataGrid I use a tall/high rows and by default DataGrid aligns row content in top vertical position, but I want to set a center vertical alignment.

I already tried to use this property

VerticalAlignment="Center"

in DataGrid options, but it doesn't help me.

Here is an example of XAML-code, describing my DataGrid without center vertical alignment:

<DataGrid x:Name="ContentDataGrid"
    Style="{StaticResource ContentDataGrid}"
    ItemsSource="{Binding}"
    RowEditEnding="ContentDataGrid_RowEditEnding">
<DataGrid.Columns>
    <DataGridTextColumn Header="UserID"
            Width="100"
            IsReadOnly="True"
            Binding="{Binding Path=userID}" />
    <DataGridTextColumn Header="UserName"
            Width="100"
            Binding="{Binding Path=userName}" />
    <DataGridTextColumn Header="UserAccessLevel"
            Width="100"
            Binding="{Binding Path=userAccessLevel}" />
    <DataGridTextColumn Header="UserPassword"
            Width="*"
            Binding="{Binding Path=userPassword}" />
</DataGrid.Columns>
</DataGrid>

Result of executing this code:

As you can see all row content has top vertical align.

What do I have to add in order to get center vertical alignment of each row content?

Complete solution of this issue at MSDN: Vertical alignment of DataGrid row content.

In brief, in style-file set:

<!--body content datagrid cell vertical centering-->
<Style x:Key="Body_Content_DataGrid_Centering"
        TargetType="{x:Type DataGridCell}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type DataGridCell}">
                <Grid Background="{TemplateBinding Background}">
                    <ContentPresenter VerticalAlignment="Center" />
                </Grid>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

In window file:

<DataGrid x:Name="ContentDataGrid"
        Style="{StaticResource ContentDataGrid}"
        CellStyle="{StaticResource Body_Content_DataGrid_Centering}"
        ItemsSource="{Binding}"
        RowEditEnding="ContentDataGrid_RowEditEnding">
    <DataGrid.Columns>
        <DataGridTextColumn Header="UserID"
                Width="100"
                IsReadOnly="True"
                Binding="{Binding Path=userID}" />
        <DataGridTextColumn Header="UserName"
                Width="100"
                Binding="{Binding Path=userName}" />
        <DataGridTextColumn Header="UserAccessLevel"
                Width="100"
                Binding="{Binding Path=userAccessLevel}" />
        <DataGridTextColumn Header="UserPassword"
                Width="*"
                Binding="{Binding Path=userPassword}" />
    </DataGrid.Columns>
</DataGrid>

This will give you a wanted result:

To set individual text alignments you can use:

<DataGridTextColumn.ElementStyle>
   <Style TargetType="TextBlock">
       <Setter Property="TextAlignment" Value="Center" />
   </Style>
</DataGridTextColumn.ElementStyle>

The following code will vertically align the content of a DataGridTextColumn cell:

<DataGridTextColumn.ElementStyle>
    <Style TargetType="TextBlock">
        <Setter Property="VerticalAlignment" Value="Center"></Setter>
    </Style>
</DataGridTextColumn.ElementStyle>

Edit: I've come back to this problem and found the solution below to work better, it will center the contents of all the cells in DataGridTextRows both horizontally and vertically.

<UserControl.Resources>    
    <ResourceDictionary>
        <Style TargetType="DataGridCell">
            <Setter Property="HorizontalAlignment" Value="Stretch"></Setter>
            <Setter Property="VerticalAlignment" Value="Stretch"></Setter>
            <Setter Property="VerticalContentAlignment" Value="Stretch"></Setter>
            <Setter Property="TextBlock.TextAlignment" Value="Center"></Setter>
            <Setter Property="TextBlock.VerticalAlignment" Value="Center"></Setter>
        </Style>    
    </ResourceDictionary>
</UserControl.Resources>

You could also do without overriding the ControlTemplate:

    <Style TargetType="{x:Type DataGridCell}">
    <Setter Property="VerticalAlignment" Value="Center" />
    </Style>

This one works for me

 <DataGrid.CellStyle>
   <Style TargetType="DataGridCell">              
     <Setter Property="TextBlock.TextAlignment" Value="Center"/>
     <Setter Property="Template">
       <Setter.Value>
         <ControlTemplate TargetType="{x:Type DataGridCell}">
           <Grid Background="{TemplateBinding Background}">
             <ContentPresenter VerticalAlignment="Center"/>
           </Grid>
         </ControlTemplate>
       </Setter.Value>
     </Setter>
   </Style>
</DataGrid.CellStyle>

回答6:

The attribute value VerticalAlignment="Center" will center the DataGrid within its parent element.

You probably want VerticalContentAlignment.

回答7:

Building on Jamier's answer, the following code did the trick for me when using auto-generated columns:

Style VerticalCenterStyle = new Style();

public MainWindow()
{
  // This call is required by the designer.
  InitializeComponent();

  VerticalCenterStyle.Setters.Add(new Setter(VerticalAlignmentProperty, VerticalAlignment.Center));
}

private void DataGrid_AutoGeneratingColumn(object sender, DataGridAutoGeneratingColumnEventArgs e)
{   
  if (e.Column is DataGridTextColumn) {
    ((DataGridTextColumn)e.Column).ElementStyle = VerticalCenterStyle;
  }
}

This is my simple solution and it just works perfectly

<DataGridTemplateColumn Header="Hello" Width="200">
    <DataGridTemplateColumn.CellTemplate>
        <DataTemplate>
            <TextBlock Text="World!" TextAlignment="Center" VerticalAlignment="Center"/>
        </DataTemplate>
    </DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>

I set the width to 200 so you can notice the difference.
