How can I make the header of datagrid as hyperlink

hello,

Right now, i had disable the "create column automatically at run time", and create column myself to display specific datafield.
and now i want to sort my data once the user click on the column header.
the 1st step i think is to make the header of column as hyperlink so that i can get the name of the column and sort by it.
Thanks for teaching.
