Custom Navigation Buttons…

While Access provides Navigation Buttons, they must always be at the bottom of the Form.  This does not work for my Form designs (Figure 1).  Using the code below you can put your Navigation buttons where you want them AND avoid the *No Current Record* message that happens when the underlying recordset contains no records.  You can also apply some *conditional formatting* making them enable/disabled based on certain criteria.

In Figure 1, I have a Main Form with a Tab Control with several Subforms.  While you can go back and forth and edit records new records are not added here.  Using code in the On_Current event of the Subform I disable the Add New button.  (To get the custom Record Count *Treatment 1 of 1* click here.)

Figure 1

However, if you open the Subform by itself, which can do from another selection on the Main Menu, you can Add New so the Add New button becomes enabled (Figure 2)….

Figure 2

Now for the code…

What are the IsLoaded lines?  They are not required for the Navigation Buttons to work.  If you are just looking for Navigation Buttons then you can safely delete those lines.  What it does do is control the scrolling of records when the Subform is opened with the Main Form but allow the scrolling of all records if opened as a separate Subform (Main Form).  So, if you want to use your Form as a Main Form AND a Subform then you will need those lines but, of course, modify to match your field names.
