We are doing an app in VB.NET 2005, current service pack level using Infragistics 7.1.x.
Every so often, a grid control will crash and return a red X within. The control turns white, gets a red inside border and a red X across the face.
The error is usually something to do with an object being invalid.
This has been a real annoying bug for us and we haven't been able to find the causation.
Thanks!
ding. I think you might be on target... there is a ton of threading going on. Many of the grids are presenting stats, so they are being retrieved in the background.
I will look into the marshalling issues.
Generally these kinds of errors happen when threading is involved, especially if it only happens occasionally. Are you doing any threading work, mainly an action that would somehow have an impact on the grid (i.e. getting data on a background thread)? You need to ensure that you marshall all these calls back to the UI thread.
