how to simulate dbnavigator??

[Richis]

I have to put all dbnavigator functions into buttons
ex:
button1 does the same like nbdelete, and button2 does the same as nb insert, and so on...
thax for advices...

For each buttons OnClick event, enter the specific code. For example, if you are using a table which is hooked upto a DBGrid via a Datasource, you do something along the lines of :-

Table1.Next; //Go Forward One Record
Table1.Prior; //Go Back back one record
Table1.First; //Go to the first record in the table
Table1.Last; //Go to the last record in the table

To delete a record, the table needs to be in edit mode, so you would need something like :-

Table1.Edit;
Table1.Delete;

There plenty on this simple sort of setup in the Delphi help.

No, I don't think it does - I've NEVER had to do an .edit before I did a .delete and I've been working in Delphi almost 10 years.

However, Richis, you will probably want to put some sort of confirmation in your delete code. Something like this:

If messageDlg('Delete this record?', 
               mtConfirmation, [mbYes, mbNo], 0) = mrYes then
  Table1.Delete;

if you use the Taction component
you assign the buttons to the actions.

then the buttons enable / disable acording to the table state ect and no code is required for append, delete save ect.
