Good morning,

I have an issue with TreeList component (in MVC) when I add the Selectable checkbox column (as first column) : in this configuration the drag & drop doesn't work correctly. 

When I try to drag a row in another position the "after" behavior would never be applied. Only the "before" and "over" behaviors seems to work correctly. All the "after" are intended always as "before".
If I simply remove the Selectable checkbox column from the configuration, all start to works fine.

Could you kindly check or give me some tips on how to solve it?

Thanks and regards,

Hello Annamaria,

 

Thank you for writing to us.

To resolve this issue, you can try to nullify the script objects demonstrated in the following solution:

Feel free to give it a try and let me know how it goes.

Hello Heyup,

unfortunately that solution doesn't change the wrong behaviour of the TreeList.

It seems that there is something wrong in the javascript code because when you don't add the Selectable column the TreeList drag & drop works fine and as expected.

Thanks and regards,

Hello

In this case, could you open a new formal support ticket where you can send us a basic runnable version of your code so we can investigate this issue further?

Then, I will modify this sample to resolve the problem and send the working version back to you. Feel free to mention this forum URL in the new ticket.
