I want to prevent the user from closing the application if they are in
the middle of entering data. Is there a way to detect this?
7  3397 
There are a couple of events you could try to catch.
The "FormClosing" event for starters..

Thanks Bala but I know where to check but I don't know what to check.
How do I detect the state of the table?

Is this a new concept?
Does no one validate whether the user wants to save/cancel changes when
the form is closing?

Depends what your datasource is.
If it's a dataset you can call DataSet.GetChanges() to get any changes (e.g.
if there are no changes than the user hasn't modified any data).
This method obviously co-incides with the functionaliy of the
AcceptChanges() method of the dataset and row and table state (New,
Modified, Unchanged, Deleted etc).

Thanks Simon,
I am used to delphi where it is very event driven. BeforePost,
AfterPost, BeforeInsert....
Dataset.State = dsEdit..., tabpage.changing (so you can prevent it)...
Got spoiled.
C# is great though, so no need to start a delphi vs c# war. Just give
me a chance to adjust.

No worries, no need to start a Delphi-C# war, Eric Gunnarson worked on
creating both C# and Delphi so it's almost like we're family. :)
