I do similar computational updates of datagrid and it works fine, I never explicitly update the grid, just the data behind it and I rely on databinding to invalidate the grid. I tend to make sure that the fields I bind to are in plain view of the binding, so no getters or properties of properties.
If I were the OP I wouldn't sit very comfortably until I had figured out why I was getting the null reference errors. One possibility is that there is something in there which is causing the update to fail silently. Once I had established that the cause was not my code, then I might start to point a finger at the datagrid. Until then I would just concentrate on the first error. Which object is causing the null reference error? --- In [email protected], "Ralf Bokelberg" <[EMAIL PROTECTED]> wrote: > > It's hard to say what the problem really is, without seeing the code. > Are you able to isolate the problematic code into a mini project and > provide it as a download? > > Cheers > Ralf. > > On Tue, Feb 12, 2008 at 8:45 AM, andrii_olefirenko <[EMAIL PROTECTED]> wrote: > > > > > > > > > > > > > > You could try this > > > > dataGrid.dataProvider.refresh(); //where dataGrid is object of > > DataGrid class > > > > Regards, > > Andrii > > > > > > --- In [email protected], "mr_j_harris" <mr_j_harris@> wrote: > > > > > > > > > > > > I need to force a redraw of a datagrid. > > > > > > Adobe's or whoever's Cleverness is not working for me. > > > > > > I just want to have my computer redraw the DataGrid from 0,0 to the > > > bottom right corner.
