Hello All,

Please help.. 

In my project i have datagridview and i have created a cellValidate event of it and in it i have put the code of e.cancel = true for certain condition like formatting and decimal validation... 

now it gives error when i press MDI form's save button to save grid records... 

IT shows... exception "Operation did not succeed because the program cannot commit or quit a cell value change"

if i remove e.cancel = true or put e.cancel = false then exception is not occurred but it can saves wrong data in database....

Please help....

Thanks in advance... 


What I have tried:

i have tried e.cancel = false in cell validate event.. by using it , not throws exception but it can save false data to database without formatting...

That is by design: it's is exactly what the Validation event is there for.
If the data in the cell isn't valid, it shouldn't be saved - and that is exactly what the system is trying to do: prevent invalid data getting into your backing storage.
