I am trying to create a style for my XamDataGrid so that I can determine what values to show in a tooltip based on the current cell that is being hovered over.

I am trying the below:

<Style x:Key="MyCVPStyle" TargetType="{x:Type igDP:CellValuePresenter}">
        <Setter Property="ToolTip">
            <Setter.Value>
                <StackPanel>
                    <ListView ItemsSource="{Binding RelativeSource={...}, Path=Field, Converter={StaticResource MyFieldConverter}}">
...

The DataContext of the style is set to the DataRecord. The problem I am having is that I do not know how to access the actual field of the cell value presenter.

I tried setting the source to:

{Binding RelativeSource={RelativeSource AncestorType={x:Type igDP:CellValuePresenter}}, Path=Field

but that fails with a binding error:

System.Windows.Data Error: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='Infragistics.Windows.DataPresenter.CellValuePresenter', AncestorLevel='1''. BindingExpression:Path=Field; DataItem=null; target element is 'ListView' (Name=''); target property is 'ItemsSource' (type 'IEnumerable')

How can I access/bind to the CellValuePresenter.Field so I can pass that value to my converter?

As a reference, I have other CellValuePresenter styles that work without issue where I access the Field. For example, here the second binding param is the Field, accessed by referencing Self:

<Setter Property="BorderThickness">
  <Setter.Value>
    <MultiBinding Converter="{StaticResource BorderThicknessConverter}">
      <MultiBinding.Bindings>
        <Binding Path="DataItem" />
        <Binding RelativeSource="{RelativeSource Self}" Path="Field" />
      </MultiBinding.Bindings>
    </MultiBinding>
  </Setter.Value>
</Setter>

    You could use the PlacementTarget property of ToolTip, which will be the CellValuePresenter, and set it as the DataContext that the ListView is binding to:

    <Setter Property="ToolTip">
    <Setter.Value>
        <ToolTip DataContext="{Binding RelativeSource={RelativeSource Self}, Path=PlacementTarget}">
            <StackPanel>
                <ListView ItemsSource="{Binding Path=Field, Converter={StaticResource MyFieldConverter}}"></ListView>
            </StackPanel>
        </ToolTip>
    </Setter.Value>
</Setter>
