wpf Datagrid Cell Formatting

Being completely novice to wpf, I am trying to get a datagrid cell formatted. I've found the following code and am playing with it, however, it does not do anything.

In this example, all I want to do is to format the columns that have a date in them. Could someone point me in the right direction???

My datagrid source is bound to a datatable in the code behind.

Please mindful that I may be using the wrong method to achieve my goal, so if you can advise what method to use(in case the AutoGeneratingColumn is wrong)...

Thanks in advance. 

private void DataGridBugLog_AutoGeneratingColumn(object sender, DataGridAutoGeneratingColumnEventArgs e)
{
    Style styleCenter = new Style(typeof(DataGridCell));
    style.Setters.Add(new Setter(HorizontalAlignmentProperty, HorizontalAlignment.Center));
    style.Setters.Add(new Setter(FontWeightProperty, "Bold"));
    style.Setters.Add(new Setter(ForegroundProperty, "Red"));

    if (e.PropertyType == typeof(System.DateTime))
    {
        (e.Column as DataGridTextColumn).Binding.StringFormat = "dd/MM/yyyy";
        (e.Column as DataGridTextColumn).CellStyle = styleCenter;
    }
}

Your style.Setters.Add should be styleCenter.Setters.Add.

Your "Bold" should be FontWeights.Bold, and also "Red" should be Brushes.Red, you can use string in the xaml side as it can convert string to the type, while from code-behind, you need set the type.

The code below works for me as expected (but I would extract the Style if need to be reused for other cells)

if (e.PropertyType == typeof(System.DateTime))
{
    Style styleCenter = new Style(typeof(DataGridCell));

    styleCenter.Setters.Add(new Setter(HorizontalAlignmentProperty, HorizontalAlignment.Center));
    styleCenter.Setters.Add(new Setter(FontWeightProperty, FontWeights.Bold));
    styleCenter.Setters.Add(new Setter(ForegroundProperty, Brushes.Red));

    (e.Column as DataGridTextColumn).Binding.StringFormat = "dd/MM/yyyy";
    (e.Column as DataGridTextColumn).CellStyle = styleCenter;
}
