Hi All, What will be possible reasons of above exception? In program once user added all data in add operation,my next operation will be view.once i click on the save button,after inserting all data i make operation as view which call view part of the program. but getting above mentioned exception at marked lines here is code
Any suggestion is highly appreciated Thanks Harshal
Harshal, While it's good to share all the information available, that is a really long code snippet. I'm not likely to read 17 screens of code (yes I counted) to deduce what line the error is being thrown on. Maybe you could start removing code to come up with a small example that illustrates the problem and point to the offending line directly?
