sorting dynamically created columns in a datagrid

[Korneel Vandamme]

problem:

i have a variable number of colums in my datagrid that i create in my
codebehind.
Once my datagrid is build, i woud like to have the possibility to sort the
datagrid, depending on when i click at my columnheader?

any suggestions/info will be very appreciated.

kind regards
