Datanase Edit confirmation

Hello!

I am having some problems confirming my data being processed. I want to confirm before i atempt to edit anything in the table, like "do you want to edit this Record?" if I dont want to, i want to just cancel it away, and exit the fiel.
I tried this way without any luck

procedure TForm1.DBNavigator1Click(Sender: TObject; Button: TNavigateBtn);
begin
 if button = nbEdit then
 if (MessageDlg('Redigere følgende post?', mtWarning, [mbYES,mbNO], 0) = mrYes) then datamodule2.DataSource1.edit else exit;
end;

You don't want to edit the DataSource, you want to edit the Table or Query that the Datasource points to, therefore:

if button = nbEdit then
if (MessageDlg('Redigere følgende post?', mtWarning, [mbYES,mbNO], 0) = mrYes) then datamodule2.Table1.edit
else exit;

or better still:

Case Button of
  nbEdit: if (MessageDlg('Redigere følgende post?', mtWarning, [mbYES,mbNO], 0) = mrYes) then datamodule2.Table1.edit;
End; {Case}

If you use a DBNAvigator, then you can place the code of jsweby in the BeforeAction-Event of you Navigator.

Right, I think there is some confusion with your use of the word Edit. Are you saying that the table is already in Edit mode, and you are asking for confirmation just before you save the record? If this is the case,then you need:

Case Button of
 nbPost: if (MessageDlg('Redigere følgende post?', mtWarning, [mbYES,mbNO], 0) = mrYes) then datamodule2.Table1.Post
  Else DataModule2.Table1.Cancel;
  nbCancel: DataModule2.Table1.Cancel;
End; {Case}

If what you asked for first time is correct, and the table is not yet in Edit mode, then you do not need to cancel anything because you are not editing or inserting.

Then you haven't put the table into edit mode! Is your user confirmation before an edit or before a post?

datasource is autoedit

jswebyCommented:
The AutoEdit property is just incase you start typing into a field without setting it into edit mode. This is generally poor programming, to allow this to happen.

You should make the user press a button (e.g. on the DBNavigator) that forces the data table into Edit mode, then you control whether to Post or Cancel these changes.

If you still want to do it your way then if the user says No, I don't want to makes these changes, simply call "Cancel".
