I've got a datagrid with one button in each row (xaml shown below). I'm trying to get rid of the blue highlighting functionality where it highlights the selected row, and the row with the mouse over it. I'm trying to seit it up so you just click on the button without getting the row selection and mouseover highlight functionality. I tried setting IsHitTestVisible to false, but then the button is not clickable. How can I do this?

The short answer is to use styles. The long answer is the following:
There are two style properties in the Silverlight 2.0 datagrid that should solve your problem. The first is CellStyle and the second is RowStyle. The CellStyle property is the one which will remove the light blue highlight around the currently selected cell. The RowStyle property is the one where you will be able to remove the light blue shade indicating the selected row. The CellStyle that I used is as follows:
<Style x:Key="CellStyle" TargetType="local:DataGridCell">
<Setter Property="Background" Value="Transparent" />
<Setter Property="HorizontalContentAlignment" Value="Stretch" />
<Setter Property="VerticalContentAlignment" Value="Stretch" />
<Setter Property="Cursor" Value="Arrow" />
<Setter Property="IsTabStop" Value="False" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="local:DataGridCell">
<Grid Name="Root" Background="Transparent">
<vsm:VisualStateManager.VisualStateGroups>
<vsm:VisualStateGroup x:Name="CurrentStates" >
<vsm:VisualStateGroup.Transitions>
<vsm:VisualTransition GeneratedDuration="0" />
</vsm:VisualStateGroup.Transitions>
<vsm:VisualState x:Name="Regular" />
<vsm:VisualState x:Name="Current" />
<!--<Storyboard>
<DoubleAnimation Storyboard.TargetName="FocusVisual" Storyboard.TargetProperty="Opacity" To="1" Duration="0" />
</Storyboard>
</vsm:VisualState>-->
</vsm:VisualStateGroup>
</vsm:VisualStateManager.VisualStateGroups>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<Rectangle Name="FocusVisual" Stroke="#FF6DBDD1" StrokeThickness="1" Fill="#66FFFFFF" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" IsHitTestVisible="false" Opacity="0" />
<ContentPresenter Content="{TemplateBinding Content}" ContentTemplate="{TemplateBinding ContentTemplate}" Cursor="{TemplateBinding Cursor}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" Margin="{TemplateBinding Padding}" />
<Rectangle Name="RightGridLine" Grid.Column="1" VerticalAlignment="Stretch" Width="1" />
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
If you will notice, I commented out the storyboard that changed the FocusVisual rectangle's opacity value. What this was doing was to set the FocusVisual rectangle to be shown on cell selection. (Please Note: You cannot remove the FocusVisual Element as the CellPresenter is expecting this element, and not finding the element will cause an error.)
The RowStyle I used is as follows:
<Style TargetType="local:DataGridRow" x:Key="MyCustomRow">
<Setter Property="IsTabStop" Value="False" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="local:DataGridRow">
<localprimitives:DataGridFrozenGrid x:Name="Root">
<localprimitives:DataGridFrozenGrid.Resources>
<Storyboard x:Key="DetailsVisibleTransition" >
<DoubleAnimation Storyboard.TargetName="DetailsPresenter" Storyboard.TargetProperty="ContentHeight" Duration="00:00:0.1" />
</Storyboard>
</localprimitives:DataGridFrozenGrid.Resources>
<vsm:VisualStateManager.VisualStateGroups>
<vsm:VisualStateGroup x:Name="CommonStates" >
<vsm:VisualState x:Name="Normal" />
<vsm:VisualState x:Name="Normal AlternatingRow">
<Storyboard>

<vsm:VisualState x:Name="MouseOver" />
<!--<Storyboard>

<vsm:VisualState x:Name="Normal Selected"/>

As you can see, I commented out some more visual states. You will want to comment out the MouseOver VisualState storyboard, the Normal Selected storyboard, the MouseOver Selected storyboard, and the Unfocused Selected storyboard.
(Please Note: I did not remove these visual states, I only commented out what they used to do.)
