I have a three level grid, bound to object data sources. The grid is working.
If a user is simply browsing dta and opens a band, closes it, and repeates that action a couple of times (anywhere from 1-4 seems to do the trick), the following error, or similar ones are displayed. The only way to get past the problem is to open another band, and come back to the first one.
Hello Peter,
Did you manage to resolve this?

Apologies for the delay.
The issue is still ongoing. I cn preproduce it within the Visual Studio IDE - simply open and close a band as few as 2 times can trigger the first error reported ont he thread.
I've attached a screenshot of what a typical pagelooks like when a band is opened. the dispalyd one will crash the second time I attempt to open it (I can go and open other bands and come back to it and it will still crash)
i've attached the code for the form, however its part os a LARGE system.key points:
- I'm using object data sources (internally stored procedures retrieve data and populate objects)
- Most of the fields are nullable, particularly string, date and the percentage values
- there are a number of dropdown editors being used in each band. Each one consists of Key/description lists (using my own object type).
- I am using the server rowinitialise event to customise the formatting of one column according to the data present. Each row in each band can have unique formatting for this column.
