Align DataGrid Column Header to Center

Question

I need to align WPF DataGrid Column Header text to Center. I created a style and attached that using the HeaderStyle property as below

Answer 1

There is a response for doing it programmatically at AutoGeneratingColumn:

 private void dataGrid_AutoGeneratingColumn(object sender, DataGridAutoGeneratingColumnEventArgs e)
    {
                e.Column.HeaderStyle = new Style(typeof(DataGridColumnHeader));
                e.Column.HeaderStyle.Setters.Add(new Setter(HorizontalContentAlignmentProperty, HorizontalAlignment.Center));

    }

Tip, use attributes:

public class ColumnNameAttribute : Attribute
{
    public HorizontalAlignment Alignment { get; set;}
    public ColumnNameAttribute(HorizontalAlignment alignment){
        Alignment = alignment;
}

public class Example(){
    [ColumnName(HorizontalAlignment.Center)]
    public string Column {get; set;}
}

 private void dataGrid_AutoGeneratingColumn(object sender, DataGridAutoGeneratingColumnEventArgs e)
{
   var desc = e.PropertyDescriptor as PropertyDescriptor;
   var att = desc.Attributes[typeof(ColumnNameAttribute)] as ColumnNameAttribute;
   if(att != null){
           e.Column.HeaderStyle = new Style(typeof(DataGridColumnHeader));
           e.Column.HeaderStyle.Setters.Add(new Setter(HorizontalContentAlignmentProperty, att.Alignment));
    }

}
