WPF

string[] columnNames = (from dc in BudgetTable.Columns.Cast<DataColumn>()
                        select dc.ColumnName).ToArray();

// Go through each column
foreach (string item in columnNames)
{
    //Creating binding
    Binding binding = new Binding(item);
    string styleName = "";

    if (item == "Type")
    {
        binding.Mode = BindingMode.OneTime;
        styleName = "budgetGridCellStyle";
    }
    else
    {
        binding.Mode = BindingMode.TwoWay;
        binding.UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged;
        styleName = "dataGridCurrencyCellStyle";
    }

    var style = Application.Current.FindResource(styleName) as Style;

    // Bind the column
    var col = new DataGridTextColumn()
    {
        Header = item,
        Binding = binding,
        Visibility = Visibility.Visible,
        CellStyle = style
    };

    DataGridColumns.Add(col);
}

<Style x:Key="dataGridCurrencyCellStyle" 
        BasedOn="{StaticResource dataGridCellStyle}"
        TargetType="{x:Type DataGridCell}">

    <Setter Property="TextBlock.Text" Value="{Binding StringFormat={}{0:0.##}}"/>
    <Setter Property="IsEnabled" Value="{Binding AreFieldsEnabled}"/>

</Style>

1. The string format setting is not being applied no matter what I change it to. What's the right way to do this?
2. The IsEnabled causes a BindingExpression error. AreFieldsEnabled is a bool property on the VM. How do I reference that from this style?
