Attachment for phone call

I'm still out of town, and I won't be flying back until Friday, which will take most of the day, so chances of me making it in to the office before Tuesday (Monday is Labor Day) are slim to none.  We can continue to try and work out the problem over the forum until then, so, if you would post everything you can think of... exceptions, inner exceptions, behaviours, etc. we might be able to get it solved before I make it back into the office.

This is probably something that I need to discuss with you on the phone. It all started out with 2 grids and 2 bo's with a relationship between them. There were so many bizarre things that happened over the course of the past week that it's a little difficult for me to even reconstruct but the basic issue was trying to add a child record in a setting where the parent-child sync was probably not setup right. I will try to call you tomorrow.



Thanks

I was able to create a sample and run it without error by using the embedded navigator in the DevExpress GridControl.  Something is different about your project... there might be an event handler that you have attached to the grid that is throwing an exception, or there might be some other issue.

I apologize for the slow response, Daniel, Trent and I are both out of town this week. 

I am not sure what is causing your problem.  The row has already been added to the business object's internal DataTable when the ListChanged event is raised, so it should not be throwing an index out of range exception.  Without stepping through your application and checking the counts and the CurrentRowIndex within your business object, and determining what index the grid is attempting to access, I am not sure what where the error is coming from. 

I am going to attempt to test the issue on a DevExpress grid and reproduce the problem.

Please note that this issue is not resolved and that I have been unable to work since last Thursday.

OK, I've found the navigator that is embedded in the DevExp grid and have enabled it. When I click its add button I get a different error in:

Protected Overridable Sub OnListChanged(ByVal e As ListChangedEventArgs)

This exception occurrs 8 times before ResultDefs_SetDefaultValues() is reached.

yes it's system.guid

If you put this in the watch window, what is the value?

this.CurrentTable.Columns["ResultDefId"].DataType

Does it show {System.Guid}?
