datagrid expression-urgent

[reiks]

My select query is a s follows
select qty from sales;

My datagrid as two template columns with textboxex in Item
template.I want to use second template column as a
compute column in my datagrid which
depends on column 'qty' values of my select statement

compute column's value should be as follows
if( qty > 10) qty+10 else
qty-10

How can give my 'DataBinder.eval(containder.dataitem))'
expression to my textbox in html?

How can I acheive this?

How complex evaluation expressions can be given for
datagrid columns either at design time or programatically?

plzzz help me out

thanks in advance,
vijaya

If you need to do something complex at bind time attach a
function to the ItemDataBound Event of the datagrid. You
will get an event for each item at which point to can
modify the databinding programmaticly
