Sort a wpf datagrid programmatically

Question

Is there a way to sort a WPF DataGrid programmaticaly ( for example, like if i clicked on my first column).

Is there a way to simuate this click ? Or a best way ?

Answer 1

PerformSort method of the DataGrid is what actually executed on a column's header click. However this method is internal. So if you really want to simulate the click you need to use reflection:

public static void SortColumn(DataGrid dataGrid, int columnIndex)
{
    var performSortMethod = typeof(DataGrid)
                            .GetMethod("PerformSort",
                                       BindingFlags.Instance | BindingFlags.NonPublic);

    performSortMethod?.Invoke(dataGrid, new[] { dataGrid.Columns[columnIndex] });
}
