How to change row background color in DataGrid (WPF)?

I need to paint some row in DataGrid in some color.

I have created collection in main UI Thread:

ObservableCollection<SomeElement> col= new ObservableCollection<SomeElement> ();

Then I change it from other thread:

int someElementNumber = 1;
int someInputValue = 11;
col[someElementNumber].SomePropery = someInputValue;

I implemented INotifyPropertyChanged Interface on SomeElement so that my DataGrid update value in that row. But I want to check this value and depend on it print row in some background color:

if (someInputValue > 10) {
    //paint row in some color
}

Please give me advice how to do it. Thanks everybody for helping in advance!

I found answer by myself. If somebody interest:

1) Make Binding with DataTrigger on CheckProperty in XAML. That property is not necessary to be visible.

<Window.Resources>
    <Style TargetType="DataGridRow">
        <Style.Triggers>
            <DataTrigger Binding="{Binding CheckProperty}" Value="Success">
                <Setter Property="Background" Value="Green" />
            </DataTrigger>
            <DataTrigger Binding="{Binding CheckProperty}" Value="Error">
                <Setter Property="Background" Value="Red" />
            </DataTrigger>
        </Style.Triggers>
    </Style>
</Window.Resources>

2) In thread, that update Collection col set CheckProperty some value depend on some condition.

int someElementNumber = 1;
int someInputValue = 11;
col[someElementNumber].SomePropery = someInputValue;
if (someInputValue > 10) {
    col[someElementNumber].CheckProperty = "Success";
}
else {
    col[someElementNumber].CheckProperty = "Error";
}

CheckProperty has to Rise Property changed event!

When that property just have been updated, DataTrigger will be invoked and it print current row in some background color depend on condition.
