How to avoid refreshing effect on a tree control while it's updating

[spaghetti_developer]

Hi Guys,

I'm populating a tree control with a lot of information and I would like to avoid that the information I'm updating are shown step by step to the user, I would prefer they will be shown when the updating procedure has finished to update the control. Is it possible to lock the control for updating and when the updating procedure is finished show the information? How can I do that?

Thank you in advance...

I agree, but PS: make sure you turn it to false after it's done (yes, I know that sounds obvious, but I was fault finding an app recently, and found that node was wired with an error cluster that had an erro upstream, so it didn't execute - very frustrating, yet highly hillarious )

Chris, that could be solved if you right click on the property node and select this option:

...but of course you need to have LabVIEW 2013 Alpha installed

These controls need a defer update method of their own IMHO.

I think there is a LVIE idea for this.

On a side note: if you are going to populate it with a lot of items (hundreds) it might be an idea to not fill it all in one go.

Add child items on demand instead, i.e. when a node is expanded (use the "Item Open" filter event to intercept). Otherwise population of the native tree control can be extremely slow and make the GUI abnormally unresponsive.

Thank you to everybody, it works very well.
