The ValueChanged event fires sometimes when the drop-down button is clicked (but before a different date is selected). I'm not sure exactly how, but this leads to a dispose call on the form and then a null-reference error. I'm using version 8.2. Any ideas on this one?
Hello ,
I have tried to reproduce your issue with Infragistics 8.2 service release 2204, which is the last service release for this volume, and everything works properly for me. Here is the sample that I used. So please download the latest service release of 8.2 and verify if your issue still exists.
Thank you.
