Good afternoon,

I keep getting the following exception when calling the function UpdateDetailGrids while scrolling.

The exception is:  The paint index cannot be equal to -1 when the row is initialized.

I'm in the main thread of the application when I try to update the control so I don't think it's a thread related issue.

Do you have an idea of what the problem could be?

Interestingly the problem occurs only when I scroll.

Thanks in adance for your help!

Sebastien
