That's interesting. If I don't call Refresh() on the ArrayCtrl, then the new information does not update.

This behavior is happening when we are getting a real-time update from a data acquisition system that uses PostCallback.
This is dispatched and processed on our UI thread. The callback simply loads the new value into the cell of intest with SetData(row,column,value).

The problem arose because this new data is not being shown.
Using ArrayCtrl.Refresh() made the new information show up
for the new information to be displayed.

That's a big hammer and takes a lot of time. The updates
are comming in at 0.12 seconds, which should not be a problem.

Do you have any idea why this is not updating based on this
additional information?

We are on Linux UPP 2007.1 release at this time.
