How to increase number of selections displayed from system combo box?

I am populating the string array of a system combo box from my program. I have a lot of elements and would like to display more than the default amount of 7 selections when the drop down is clicked.

I know this can be done easially in MS Access but I don't see a obvious property I can set in the property nodes.

Thanks!

Hi,

At first glance with the property nodes of the system combo box control, I do not unfortunately think you can change the displayable items after clicking the down arrow to allow more than 7 to be displayed.  This however, is an excellent product suggestion and I highly suggest you request this feature for future versions of LabVIEW.  You can file a product suggestion through the link provided here.

@Nadim R
Thank you for your response. I will stop looking for the feature!

I posted the suggestion for improvement as you suggested.

This feature would be nice.  Someone asked me if I could increase the number of dropdown items of a combobox in my GUI just today!  (LV2011)

While you can't control this with the various drop downs in LV, you could either implement the list yourself (as a popup VI) or use an ActiveX/.NET combo box, which presumably will support this.

Also, if you want this to actually be in LV, I would suggest adding it to the idea exchange (search first to see if it isn't already there).

You can create an xctrl for that.

Define the height yourself.

See attached demo.

Cool, at least I know there's a workaround now.  When I have some free time I'm going to look into how easy it is to implement this although I'd rather have it be a property of the native control.

Thanks,
