wpf Datagrid Cell Formatting

Question

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;
}
