There are several ways to sort data in C# but one of the easiest ways is using BindingSource sort capability.
Depending on what object (underlying list) is linked to the BindingSource as its DataSource and whether it has implemented IBindingList or IBindingListView interfaces or not, you can use this feature.
To find out whether a BindingSource with current DataSource supports sorting, use ‘SupportsSorting’ property:
if (bindingSource1.SupportsSorting)
{
bindingSource1.Sort = "Code, Name";
}
Similarly, you can benefit from BindingSource.Filter .
C# Tips 
This looks a very simple and concise way to sort the data source before binding it to any control.It is a way better approach as compared to the custom data source sorting as it requires some markup and events handling.I needed something like that
