Re: [MS_AccessPros] list box defaults

 

Your are correct, these are unbound list boxes.

I changed the OnOpen event from

me.lstCorporations.defaultvalue = glngCorporationID

to

me.lstCorporations.value = glngCorporationID

I'm sure it is no surprise to you, but it now works.  If you don't mind taking the time please, I would like to understand the "why" of this.  In both cases I am referencing the same control (me.lstCorporations).  Setting the default value does not work, but does not throw an error.  Setting the Value works.  

On several other forms (similarly, subforms of the Nav form control) I have unbound combo boxes.  And for those combo boxes in the form OnOpen event, I am setting the combo value with:

cboCorporation.DefaultValue = glngCorporationID

and that is working with no problem.

Can you please explain why this works this way?  Unbound List boxes cannot have default values, and instead only have values;  but unbound combo boxes can have default values?

Are the list boxes bound?  If not, then setting the Default Value will do nothing.  Set the value of the controls instead.

My application is contained within a Navigation form.  It starts with a login form which collects some default values for corporations, locations and sites, as well as the UserID, and stores them as global variables. One of my Navigation tabs contains three cascading list boxes - lstCorporations, lstLocations and lstSites.  When that tab is clicked, I am wanting these list boxes to open with the default values from the login form already selected in the list boxes.

I tried setting the default values for each list box control to the values of the global variables, and I tried setting the default values in the form open event.  Neither seems to impact the list boxes.

How can I accomplish this?
