Try Catch Not working porperly...
-
Hi, In my website i have a report where i have implemented try-catch try { ... ... } catch(Exception) { return; } but even on appling try-catch on every event my report sometimes gives error like "INPUT STRING IS NOT IN CORRECT FORMAT". I have tried my best so that data type mismatch should not occur. This problem is significant with this report only. Help me.

I guess the exception is catched within the report, so that your try-catch-statement will not be executed.
It's not a bug, it's a feature! Check out my CodeProject article Permission-by-aspect. Me in Softwareland.

I cant understand what you mean by this. If i am handling the exception before any function or data conversion executes then how this error can come.
Is an exception thrown? If not, how is the error displayed, within the report?

Hi Abhijit, Even on entering special charatcers , report is working fine. I cant fnd this error on local and only once on server but my clients have reported it many times. I am not undertaking any data conversions. I have text boxes for dates and i have tested it several times they are working fine. Even I cant understand why this error is coming as on local and even on server i cant find this error except only 1 time with all types of input.

Then why you are not asking client for data and tested with those data. I think there may be some script problem.

On this page i have only two textboxes for input that are used for entering dates. And i have tested it with every type of incorrect input. It is not giving any error.
Did you tried with this < > cheers, Abhijit CodeProject MVP

trytocatchme if you can :jig: some one is eating the exception. If the exception is not re-thrown then there is nothing you can do.Yusuf Oh didn't you notice, analogous to square roots, they recently introduced rectangular, circular, and diamond roots to determine the size of the corresponding shapes when given the area.
