<p>Just put instead </p>

<pre><code>&lt;Style TargetType="{x:DataGridCell}" &gt;
</code></pre>

<p>But beware that this will target ALL your cells (you're aiming at all the objects of type <code>DataGridCell</code> )
If you want to put a style according to the cell type, I'd recommend you to use a <code>DataTemplateSelector</code></p>

<p>A good example can be found in Christian Mosers' DataGrid tutorial:</p>

<p>If you try to set the <code>DataGrid.CellStyle</code> the DataContext will be the row, so if you want to change the colour based on one cell it might be easiest to do so in specific columns, especially since columns can have varying contents, like TextBlocks, ComboBoxes and CheckBoxes. Here is an example of setting all the cells light-green where the <code>Name</code> is <code>John</code>:</p>
<pre><code>&lt;DataGridTextColumn Binding=&quot;{Binding Name}&quot;&gt;
    &lt;DataGridTextColumn.ElementStyle&gt;
        &lt;Style TargetType=&quot;{x:Type TextBlock}&quot;&gt;
            &lt;Style.Triggers&gt;
                &lt;Trigger Property=&quot;Text&quot; Value=&quot;John&quot;&gt;
                    &lt;Setter Property=&quot;Background&quot; Value=&quot;LightGreen&quot;/&gt;
                &lt;/Trigger&gt;
            &lt;/Style.Triggers&gt;
        &lt;/Style&gt;
    &lt;/DataGridTextColumn.ElementStyle&gt;
&lt;/DataGridTextColumn&gt;
</code></pre>
<p><img src="https://i.stack.imgur.com/PBJcX.png" alt="A Screenshot" /></p>
<hr />
<p>You could also use a <a href="http://msdn.microsoft.com/en-us/library/system.windows.data.ivalueconverter.aspx" rel="noreferrer"><code>ValueConverter</code></a> to change the colour.</p>
<pre class="lang-cs prettyprint-override"><code>public class NameToBrushConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        string input = (string)value;
        switch (input)
        {
            case &quot;John&quot;:
                return Brushes.LightGreen;
            default:
                return DependencyProperty.UnsetValue;
        }
    }

    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        throw new NotSupportedException();
    }
}
</code></pre>
<p>Usage:</p>
<pre><code>&lt;Window.Resources&gt;
    &lt;local:NameToBrushConverter x:Key=&quot;NameToBrushConverter&quot;/&gt;
&lt;/Window.Resources&gt;
...
&lt;DataGridTextColumn Binding=&quot;{Binding Name}&quot;&gt;
    &lt;DataGridTextColumn.ElementStyle&gt;
        &lt;Style TargetType=&quot;{x:Type TextBlock}&quot;&gt;
            &lt;Setter Property=&quot;Background&quot; Value=&quot;{Binding Name, Converter={StaticResource NameToBrushConverter}}&quot;/&gt;
        &lt;/Style&gt;
    &lt;/DataGridTextColumn.ElementStyle&gt;
&lt;/DataGridTextColumn&gt;
</code></pre>
<hr />
<p>Yet another option is to directly bind the <code>Background</code> to a property which returns the respectively coloured brush. You will have to fire property change notifications in the setters of properties on which the colour is dependent.</p>
<p>e.g.</p>
<pre class="lang-cs prettyprint-override"><code>public string Name
{
    get { return _name; }
    set
    {
        if (_name != value)
        {
            _name = value;
            OnPropertyChanged(nameof(Name));
            OnPropertyChanged(nameof(NameBrush));
        }
    }
}

public Brush NameBrush
{
    get
    {
        switch (Name)
        {
            case &quot;John&quot;:
                return Brushes.LightGreen;
            default:
                break;
        }

        return Brushes.Transparent;
    }
}

<p>This may be of help to you. It isn't the stock WPF datagrid however.</p>

<p>I used DevExpress with a custom ColorFormatter behaviour. I couldn't find anything on the market that did this out of the box. This took me a few days to develop. My code attaached below, hopefully this helps someone out there.</p>

<p>Edit: I used POCO view models and MVVM however you could change this to not use POCO if you desire.</p>

<p>Based on the answer by 'Cassio Borghi'. With this method, there is no need to change the XAML at all.</p>

<pre><code>        DataGridTextColumn colNameStatus2 = new DataGridTextColumn();
        colNameStatus2.Header = "Status";
        colNameStatus2.MinWidth = 100;
        colNameStatus2.Binding = new Binding("Status");
        grdComputer_Servives.Columns.Add(colNameStatus2);

        Style style = new Style(typeof(TextBlock));
        Trigger running = new Trigger() { Property = TextBlock.TextProperty, Value = "Running" };
        Trigger stopped = new Trigger() { Property = TextBlock.TextProperty, Value = "Stopped" };

        stopped.Setters.Add(new Setter() { Property = TextBlock.BackgroundProperty, Value = Brushes.Blue });
        running.Setters.Add(new Setter() { Property = TextBlock.BackgroundProperty, Value = Brushes.Green });

        style.Triggers.Add(running);
        style.Triggers.Add(stopped);

        colNameStatus2.ElementStyle = style;

        foreach (var Service in computerResult)
        {
            var RowName = Service;  
            grdComputer_Servives.Items.Add(RowName);

<p>I have got a WPF datagrid and I want diffrent cell colours according to values. I have got below code on my xaml</p>

<pre><code>Style TargetType="DataGridCell"
</code></pre>

<p>but instead of selecting a cell only is selecting all row? What am I missing?</p>


Change DataGrid cell colour based on values

我有一个WPF数据网格，我想根据值不同的单元格颜色。我在我的xaml上有以下代码Style TargetType="DataGridCell"但是，不是只选择一个单元格，而是选择所有行？我遗漏了什么？
