Drag and Drop cannot work properly on Mac OS x

Hello
My client wants to use web service built by Net Diagram(MindFusion.Diagramming for ASP.NET, version 4) on Mac OS x (10 . 6. 8 ), she cannot use safari or firefox to drag and drop function on mac,

In this web service Drag and drop means ‘Drag a predefined shape from ShapeListBox object to DiagramView object’

So I updated latest version of Java and opened java console to see is there any error come out, there is no message and no error on Java console when doing drag and drop.
The version of mac system is Mac OS x (10 . 6 . 8 )
Safari - Version 5.1 (6534.50)

Firefox version - Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv: 1.9.2.22) Gecko/20110902 Firefox/3.6.22

But it works on windows OS.
Could you give us any solution?
Many thanks

Hi,

It seems drag and drop to Java applets hasn't been working for some time on MacOS, both Safari and Firefox posts here:
https://bugzilla.mozilla.org/show_bug.cgi?id=588455

Our developer will try to debug that on Mac, but if the applet does not receive drag events as reported above, there won't be much we can do. For the time being you could let your client draw nodes directly with the mouse, or create them from the DoubleClicked script.

Hi,

We have debugged this on MacOS and apparently applets do not receive drag-and-drop events at all, neither external ones nor ones coming from inside the applet. Given that Apple will no longer develop its own version of Java, there probably won't be a fix for this until Oracle release their Mac version.

Meanwhile we have implemented a new "Canvas" mode in Netdiagram 4.1 (beta version at http://mindfusion.eu/Forum/YaBB.pl?board=netdg_disc;action=display;num=132030776...). Drag-and-drop from the ShapeListBox works fine in that mode, so you might check if it provides the features you are currently using.

There's still a lot of stuff missing though from our Canvas js library, such as expand/collapse, support for custom shapes, lane grid, etc. If Canvas mode won't work for you, we could think of some work-around in applet mode, where nodes are created by selecting in the listbox and (double)clicking on the diagram.

Dear Sir/Madam,

Thanks for giving me a valuable reply, I downloaded V4.1 then replaced all dll files in bin folder. Recompile the whole project. First I tried to make sure this is trial version 4.1 beta shown on the diagram and then I tried to use drag and drop function. the result is sad, It didn't work.
Is there any solution to trigger it?
Many thanks

Have you set the ClientSideMode property to Canvas? It still defaults to JavaApplet.

I think you must set ClientSideMode on the Overview and ShapeListBox controls too.

Hello

Thanks for replying,

I added this to others , it didn't work. it came out blank and grey on object.
it is the problem of using Net Diagram 4.1 beta ?
Our current environment is ASP.NET 2.0.

Many thanks

We released version 4.1 yesterday. To enable canvas mode, you must add mindfusion.diagramming.js to your project, and either add a ScriptManager to the page or directly load MicrosoftAjax.js:
http://www.mindfusion.eu/onlinehelp/netdiagram/index.htm?Setting_up_Canvas_Mode....

The Fractal Layout demo here uses Canvas mode, from what I can see it works fine both in Safari and Firefox on Mac:

I hope that helps,
Stoyan
