Set the subforms ControlSource in the tab controls change event.

Posted on 2014-03-31
Last Modified: 2014-04-01
I  have a main form with a tab control that contains 5 subforms.   This form takes a long time to load due to all the data contained in each of the subforms.  I've done some research on here and it seems a good solution might be to only load the first default tab, and then load the remaining tabs when each is clicked.  However, I'm not sure how to do this.

Any help will be much appreciated. Thanks!

Remove the SourceObject name from the hidden subforms.  When a tab gets focus, set the SourceObject for that subform.

Ok thanks.  It's been a while since I've done any VBA programming, so please bear with me.  Will I do this with case statements inside the On Change event of the tab control?

Yes.  I don't have any examples handy and I don't do this frequently enough to remember the property but it is a property of the tab control.

Select Case Me.yourtab.someproperty
    Case "Pg1"
        Me.sfrmPg1.ObjectSource = "somename"
    Case "Pg2"
        Me.sfrmPg2.ObjectSource = "somename2"

I don't understand what "sfrmPg1" is referencing.  I have a main form with one tab control that contains 5 pages.  Each of the 5 pages contains a subform.

Each subform control has a Name property.  Usually it is the same as the ObjectSource name but it doesn't have to be.  "sfrmPg1" is the Name property of the control whose ObjectSource you want to set.

That is what I thought.  Thanks for the clarification
