    copied!<p>first of all, I'd advise you to update to .net 4.0 to be able to use the WPF dataGrid without resorting to installing the WPFToolkit.</p> <p>now as for your issue, you have to set a style to your datagrid, and inside the style, template or resource put this kind of code:</p> <pre><code> &lt;Style TargetType="{x:Type Button}" x:Key="{ComponentResourceKey ResourceId=DataGridSelectAllButtonStyle, TypeInTargetAssembly={x:Type DataGrid}}"&gt; &lt;EventSetter Event="PreviewMouseDown" Handler="SelectAllButtonPreviewMouseDownHandler" /&gt; &lt;EventSetter Event="PreviewMouseUp" Handler="SelectAllButtonPreviewMouseUpHandler" /&gt; &lt;Setter Property="ToolTip" Value="{Binding SelectAllButtonToolTip, RelativeSource={RelativeSource AncestorType=DataGrid}}" /&gt; &lt;Setter Property="Content" Value="{Binding SelectAllButtonContent, RelativeSource={RelativeSource AncestorType=DataGrid}}" /&gt; &lt;Setter Property="Focusable" Value="False" /&gt; &lt;Setter Property="Template"&gt; &lt;Setter.Value&gt; &lt;ControlTemplate TargetType="{x:Type Button}"&gt; &lt;Grid Background="Transparent" VerticalAlignment="Stretch" HorizontalAlignment="Stretch"&gt; &lt;Polygon Name="Arrow" HorizontalAlignment="Right" VerticalAlignment="Bottom" Margin="0,0,3,3" Points="0,9 9,9 9,0" Fill="Black" Opacity="0.15" Visibility="Collapsed"/&gt; &lt;ContentPresenter Name="ContentSite" /&gt; &lt;/Grid&gt; &lt;ControlTemplate.Triggers&gt; &lt;Trigger Property="Content" Value="{x:Null}"&gt; &lt;Setter TargetName="ContentSite" Property="Visibility" Value="Collapsed"/&gt; &lt;Setter TargetName="Arrow" Property="Visibility" Value="Visible"/&gt; &lt;/Trigger&gt; &lt;Trigger Property="IsMouseOver" Value="True"&gt; &lt;Setter TargetName="Arrow" Property="Opacity" Value="0.75"/&gt; &lt;/Trigger&gt; &lt;/ControlTemplate.Triggers&gt; &lt;/ControlTemplate&gt; &lt;/Setter.Value&gt; &lt;/Setter&gt; &lt;/Style&gt; </code></pre> <p>(this is a sample from some code of mine, that I put in MyDataGrid.Resources, MyDataGrid being a class derivated from DataGrid)</p> <p>edit: the important part is of course the <code>x:Key="{ComponentResourceKey ResourceId=DataGridSelectAllButtonStyle, TypeInTargetAssembly={x:Type DataGrid}}"</code> in the button's style declarator.</p>
