How do I fire a method for a WPF setter that has the parent as a parameter?

Binding

Hi,

I tried to create a method that set the color of a DataGridCell calculating it.
I created a resource that use this method:

<UserControl.Resources>
    <ObjectDataProvider ObjectType="{x:Type l:D}"
              MethodName="CalculateBackColor" x:Key="CalculateBackColor">
        <ObjectDataProvider.MethodParameters>
            <system:Object/>
        </ObjectDataProvider.MethodParameters>
    </ObjectDataProvider>
</UserControl.Resources>

NB: I used an Object parameter because I tried to pass the cell itself or the DataGridCellInfo, but I don't know how. I used Object only for attempts. In a future, it will be

<ObjectDataProvider.MethodParameters>
    <DataGridCell/>
</ObjectDataProvider.MethodParameters>

I tried to bind this method to the background of the cell.

<DataGrid IsReadOnly="True" ItemsSource="{Binding}">
    <DataGrid.CellStyle>
        <Style TargetType="DataGridCell">
            <Setter Property="Me" Value="{Binding
                    Source={StaticResource ResourceKey=FromDRToColor},
                    Path=MethodParameters[0], BindsDirectlyToSource=True}" />
            <Setter Property="Background" Value="{Binding
                    Source={StaticResource ResourceKey=FromDRToColor}}"/>
        </Style>
    </DataGrid.CellStyle>
</DataGrid>

Naturally, Setter Property = "Me" doesn't run.
Even inserting Setter Property = "Content" instead of "Me", the function receives as a parameter a null (perhaps because even the content has not been set, or maybe because I was wrong syntax)
How do I have to do?
