Dataset State

[MarkusR]

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?

Re: Dataset State

There are a couple of events you could try to catch.
The "FormClosin g" event for starters..

Re: Dataset State

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?

Re: Dataset State

Is this a new concept?

Does no one validate whether the user wants to save/cancel changes when
the form is closing?

Re: Dataset State

Depends what your datasource is.
If it's a dataset you can call DataSet.GetChan ges() 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).

Re: Dataset State

Thanks Simon,

I am used to delphi where it is very event driven. BeforePost,
AfterPost, BeforeInsert... .
Dataset.State = dsEdit..., tabpage.changin g (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.

Re: Dataset State

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. :)

Re: Dataset State

I miss my numbered bookmarks as in Delphi. :(
