UniTreeView issue

Hi,

I use UnitoolBox for years now without issues. But, today, I have to replace a VB Treeview with a UniTreeView control. When I do that, the UniTreeView has only 4 events like Lost or GotFocus, and I haven't anymore events like Collapse, Expand or NodeCheck.

It seems that UniListView has similar issue.

Can somebody help me, please?

Yes you're correct that the UniTreeView does not have every event that is avialbable on the MS control, however we do have the majority of the events. Appologies for any frustration caused.

Hi,

Thanks for your answer.

I don't speak about one or two events missing. In my case, when I put this control on a form, I can use only events LostFocus, GotFocus, DragDrop and DragOver.

It seems that the issue come from VB5 (sorry, it's a very old release), because on VB6 it's running well

Thanks again

Ah right, yes you will have some problems in VB5, I would not be surprised at that. You should really be using VB6 at this point.

IIRC, VB5 listview and treeview already support Unicode (They need some tweaks here and there but they still do.). So you should be fine anyway.

Hello,

To be more precise, the TreeView version from MS Windows Common Controls 5.0 does support Unicode. What a blessing! The UniTreeView is almost unusable because in addition to compatibility problems, it is *unbelievably* slow.

We have benchmarked all the UniToolbox controls and found no major speed problems. Please take a look at the demo apps and you can see more details on how to use the controls successfully.

Hi,

Same issue here. UniTreeView is unbelievably slow. Any chance you could release an update to the existing controls fixing some of the bugs?
