[CLOSED] How to disallow grid drag drop if different groups are selected / disallow dropping in other group

[blueworld]

Hello.

I have a grid with a drag drop plugin that allows to reorder rows in order to change internal position values.
This works fine so far but currently I'm stuck at two additional requirements caused by grouping.

1. The user should not be able to drag rows if he has selected rows from different groups
If it is not possible to block the dragging, at least the user should not be able to drop them anywhere

2. The user should not be able to drop the record into a different group


I have these problems because the grid itself is a valid drop element, therefore I can drag drop them among different groups.

Any idea how I could solve that problem?

Hi @blueworld,

There should be some "beforedrag" (not sure about the name) which should allow to prevent dragging.

I would search Ext JS API docs for "beforedrag".

Maybe, you will need to override some method of the Ext.view.DragZone class.

Hi Daniil,

thank you.

If I take an easy example, drop a record from group A into Group B.
I know that I can get both records (the dragged one, and the one where I drop it before or after) as overModel and data.records[0]

Is there a property that determines the current group of a record, like (if overModel.group.name != data.records[0].group.name) ..... ?

There is the getRecordGroup method.

Hope this helps.
