Block drop in certain swim lanes

[Trevor]

Hi,

If i have the following swim lanes

Open

Started

Paused

Closed

How can I prevent certain operations while allowing others e.g

I can drag from open to Started

I can  drag from Started to Paused or closed

I want to prevent drag from Started, or Paused to Open.

Is this possible and if so could you please provide some guidance.

TIA

Trevor

Hi Trevor, 

 

Thank you for contacting Syncfusion support.   

   

Please confirm us whether you need to prevent drag operations between Kanban columns.   

 

-                      Between vertical columns ( eg . from Open to Started ) 

 

 

 

Or Kanban Swim-lanes  - drag and drop between highlighted horizontal lanes? ( eg . from Open to Started ) 

 

Based on your confirmation, we will provide you the appropriate solution. 

Regards,

Sorry, yes indeed it is between the vertical columns I wish to block certain drag/drops.

TIA
