I have a grid in my application with an unbound formula column that is a simple multiplication of two cells. This column has a summary in the groupby row. In my application, if the data is reloaded, the following error is produced:
An unhandled exception of type 'System.NullReferenceException' occurred in Infragistics4.Win.UltraWinGrid.v12.2.dll
Additional information: Object reference not set to an instance of an object.
If I remove the summary, the exception is not thrown. I am using version 12.2.20122.2018. I see quite a few posts similar to mine in nature, but most seem to indicate the issue should have been resolved in previous releases.
It is dependably replicated, so if you need a sample project I'm sure I can provide one.
Thanks for any assistance you can provide. It is fairly important that I summarize this column.
Hi,
That does sound like a known bug that was fixed. So my first recommendation would be that you get the latest service release. The build you are using is not the latest.
How to get the latest service release - Infragistics Community
I'm pretty sure that will fix it - there were a number of issues and complications in this area around that time and they were all fixed. But if that doesn't help, please post a small sample project and we will be happy to check it out.
Hmmm - I was hoping to have a workaround I could employ myself. I have not subscribed for the latest release and the company I work for would prefer to skip a year between versions. In understand that doesn't work well in events such as this, but this direction doesn't come from me.
Thanks for the reply. Back to the drawing board...
Well, the service release is free - you don't need a subscription.
You could try changing the FormulaRowSourceIndex property on the override to RowIndex or ListIndex and that might help. But if not, there's probably nothing you can do.
Oh I see! I apologize for not reading through the post you linked more thoroughly. Thank you very much!
I will try the service release and update you on the results :)
No dice. Same error as before.
