drag and drop does not work correctly

Hi, 

I have a problem with the drag and drop when i have a large data the event is not following the mouse correctly and the dragging is too long (the function "drag" is not called correctly) , also the drag and drop sometimes blocks,  i can't detect the event of the function "dragStart" but i can do the resize / Edit / delete / create .

I use the external drag and drop with the tree view , When the drag and drop is blocked in the schedule  i can't do the drag and drop from the tree view to the schedule.

the "allowDragAndDrop" is true.


Thank you in advance.

Lydia

Hi, 

thanks for your response,

the probleme is the data in the args of Drag is null therfore the drag and drop action is blocked. I would like konw if there is a way to correct it or return to normal drag and drop behavior

Hi Lydia, 
 
Thanks for your update. 
 
We have checked your shared script error at our end. But, we are unable to reproduce the issue at our end and it works fine. Based on your shared script errors, we suspect that some duplicate packages might be installed in your ‘@syncfusion’ folder of ‘node_modules’. Please follow the below steps to overcome the reported behaviour.  
 
1. Delete package.lock.json file from your application.   
2. Remove the @syncfusion package folder from the node_modules.   
3. Use same version for all components in package.json file.   
4. Then install the new packages.   
 
  
If you still facing the same problem, kindly share the below details it helps us to resolve your problem ASAP 
  
  1. Complete schedule and tree view rendering code.
  2. Whether you use the `eventDragArea` property in your scheduler code.
  3. Share a issue reproducing sample which would help us to proceed further.
 
Regards, 
Vinitha
