DataGridView, how to disable cell validation on closing form?

DataSource is an ArrayList.
Some of the columns have Format = N2.

The problem is that if I enter invalid data into an N2 formatted column
I cannot close the form by clicking on the form's Close (X) button,
FormClosing fires after cell validation.

I don't want to do my own cell formatting nor validation nor add my
Close button.

Is there any clever way of solving this problem without using Win API?

Thanks

I've not fully tested this potential solution, but the Form class has a
Closing event and assuming this event fires first before the validation of
your DataGridView you could then disable the DataGridView validation.
Alternatively, you could subclass your Form with an abstract FormBase class
which contained a FormClosing boolean property which could be set by the
forementioned Closing event. Then the validation event handlers could check
this boolean value before validating the data.

Hope that all makes sense...

Hi,
I'm not sure i understand Your question well.
If You have a filename in Your application and You wish to open it in the
default program Windows uses to open it in, use the Process.Start(string
fileName) method.
For example this:
Process.Start(@"c:\myfile.txt") ;
will open myfile.txt in notepad (assuming Your system maps notepad for the
extension of txt).

Please let me know if i misunderstood Your question.

Hope You find this useful.
