Funny...this is exactly my situation. See my post on Dynamic components from a couple days ago. Unfortunately, this statement won't work: c.Map(x => (string)x[temp]);
because the variable temp isn't evaluated in the loop; the statement is turned into an expression tree and evaluated later; at which time "temp" won't exist. I've been trying all sorts of things the past few days, and may be close to a solution involvoing manually building the expression tree. Should know more on Monday. Keep me posted if you figure something out! On Jun 20, 8:45 am, Paul Batum <[email protected]> wrote: > Hi Silvia, > > Can the column details be discovered at startup time?
