WinForms, Citrix, Infragistics and a BIG red X

[Patrick O'Gorman]

We have developed a Windows Forms MDI application that runs over Citrix ICA.
We use Infragistics for various UI controls.

Every once in a while when a user loads data into a grid they will get a big
red X in the area usually consumed by the grid and a JIT error box with no
real meaningful information (of course no data is visible). This has
happened 99.5% of the time over Citrix, although a few developers have seen
it once or twice on their dev PCs.

Any ideas/thoughts?

Thanks.

It means that there is a bug in the paint routine. You should report that to Infragistics, definitely there is a platform incompatibility, probably fixable...

I appreciate your reply. Is there anything else you can tell me about this?
It just seems odd that it only happens, well usually (with strong emphasis
on usually) happens over Citrix ICA.

Thanks again.

Are you using Multiple Threads? This is a probable cause of this issue.

If you are calling the data load and bind on a separate thread you should consider switching to using Control.Invoke at the form level.

VB

Me.Invoke(New EventHandler(AddressOf yourProcessName))

C#

this.Invoke(new EventHandler(yourProcessName));
