[CLOSED] Treepanel drag drop does not work in V3

[Fergus]

Hi,
The drag drop between nodes does not work anymore in V3. Not sure exactly when this happened.

You can see the problem here - https://examples3.ext.net/#/TreePane...Between_Trees/

It seems to work in Firefox but not in Chrome or the new Edge browser. Cannot seem to get a hold on the node.

Thanks
Fergus

Update:
I tried this on another computer and it worked fine in Chrome.

I wonder is this again to do with me using a touchscreen laptop.
Maybe somebody else has seen strange behaviour like this on touch screen laptops?

If so, is there a possible fix?

Thanks

I have reports from users that Drag/Drop is broken in our grid. We use a DropTarget.

We finally just realized that user has a touch enabled screen and this is the likely cause. I will be building a example this week if i can get time to meet with the customer.

I did file a separate ticket that touch screens cause screens not to load/work properly and you can have an issue if your Viewport as AutoScroll=true (http://forums.ext.net/showthread.php...ome-and-Win-10)

Hello!

Tried that example in Safari on ipad - drag&drop works. It looks like it requires a LongPress event - when you tap and hold more than 1 second.

I am working on a touch screen laptop which when you long press it brings up the context menu. You can then sometimes get a handle to drag and sometimes not.

But the main problem i am having is that i cannot even drag with my mouse. I notice that i can drag with a mouse with the new version of Ext.js V6. And the touch move works better as it starts to drag before the context menu shows.

I cannot drag at all with the current version of ext.net.

Is there any release date on the new Ext.net 4 (extjs 6) where sencha touch and extjs are combined?

Thanks

Please clarify what OS is on the laptop. I guess Windows 8 or 10?

Is there any release date on the new Ext.net 4 (extjs 6) where sencha touch and extjs are combined?

The first Ext.NET 4 release (probably, beta) might appear early in 2016.

same exact problem and likely the same bug for TreeGrid
