Making a Tabbed Form Faster

Forms with tabs can be slow sometimes, especially if there are a large number of controls on each tab. Here's how to make them faster.

Break up your form into multiple forms (one for each tab). You still can have tabs to move around...they just will work differently.

Say you have a form with three tabs (tab-a, tab-b, and tab-c). Create three forms (form-a, form-b, and form-c). All the forms will have the three tabs.

Form-a's tab-a will have controls on it, but tab-b and tab-c are empty.

Form-b's tab-b will have controls on it, but tab-a and tab-c are empty.

Form-c's tab-c will have controls on it, but tab-a and tab-b are empty.

On form-a, create a macro (EDIT | MACRO/EVENTS) that detects what tab is selected (@currenttab) and then launches the appropriate form. Use the EVENTS button in EDIT | MACRO/EVENTS to set the "On select tab" event to run your macro.

Do the same for form-b and form-c.

Top rated! I needed a solid database application development tool for mobile devices. I chose DroidDB for Android OS because it provided a way to get a strong product to market quickly. DroidDB is relational, gives me control over form layout, handles macros, and supports events. It works on all Android versions I have tried and is a great companion product to SYWARE’s VisualCE.
