View Full Version : How do I mark a grid's contents as invalid?

14 Dec 2009, 5:58 PM
I have grids within several different panels whose contents depend on an exchange currency which is selected by the user. The grid contents need to be determined on the server side because it is more complicated than just multiplying everything by a conversion rate(the conversion rate my be different depending on the date of the transaction). But I don't need to update all grids right away, in fact, that is what I am trying to avoid because it would be quite inefficient. When the exchange currency is changed, I want to somehow mark the grids as invalid and then load the data for a particular grid when the user has switched focus to the grid. Any suggestions?
