Hi Soykan,
We develop that kind of ToolBar, part of our framework called Base_act.
It is done as CoolBar with Buttons New, Edit, Delete, Save, First, Previous, Search, Next, Last, Preview, Print, Send to XLS, Send to PDF.
It has no code in it, because in each form there are different rules to determine what button will be Enabled and what code will be executed. So our toolbar relies on forms properties such as FirstBtn, PrevBtn etc. and executes forms methods FirstData, PrevData etc. Every one of these methods takes carry to set the right values into corresponding properties.
For PrevData method we use code as:

SELECT TOP 2 * FROM myTable order by myId DESC WHERE myID < currentRecordID

In this case if we have 2 records in the result cursor PrevBtn remains Enabled other wise is becomes Disabled.
The code is similar for other methods.
