Hi Tim. I'm not worried about duplicating code, the calculations are already implemented in a different function, since the first two label function use them. I want to save the computing time of doing the calculations again...
And I do want to look at the datagrid and not the data (unless I'm missing something). The data is raw - meaning it is the data prior to the calculations. I want to have the data after the computations, and use it in the third labelFunction... I'll try and explain a bit more the situation (a bit simplified): The raw data in the DataGrid dataprovider is VOs with various members, Dates among them. The second column displays the startDate after calculations (made in the second column's labelFunction). The third column displays the endDate after calculations (made in the third column's labelFunction). The forth column should display a value based on the data of the second and third columns, but I need the values AFTER the calculations and not the raw data. That is why I need the data in the datagrid columns themselves (since they are the computed data) and not the raw data in the dataprovider... Hope that makes the situation clearer, hopefully will help you guys help me :) Thanks, Sefi On Fri, Aug 22, 2008 at 7:42 PM, Tim Hoff <[EMAIL PROTECTED]> wrote: > > You don't want to look at the grid, you want to look at the data.
